6. Conservation status, habitat selection, and indicator ­species Introduction In the previous two chapters I have demonstrated how species-rich tropical bird communities can be assessed and monitored effectively. However, the resulting wealth of data is very complex, and it is ­ob­viously not a simple task to apply this information in practical conservation. Here I will discuss some options on how the avifaunistic data gathered at Playa de Oro can be analyzed in order to obtain prac­ tical information permitting conservation-oriented interpretations. To facilitate the maintenance of biodiversity in human-influenced landscapes through the establishment of nature reserves, adaptive management of natural resources, and mitigating measures for environmentally adverse operations, basic information on the status and distribution of biological taxa and their habitats is required. However, especially in tropical countries, comprehensive inventories of various plant and animal groups are usually not feasible due to lack of funds and time (Pearson 1994, Kerr et al. 2000). It has been estimated that an all-taxa inventory of just one hectare of tropical humid forest might take 50-500 researcher years to accomplish (Lawton et al. 1998). Not surprisingly, contemporary conservation biologists and managers have therefore increasingly used indicator species (or species groups) as a shortcut to monitoring and solving conservation problems (Raven & Wilson 1992, Flather et al. 1997, Caro & O’Doherty 1999). Surrogate species are principally employed in two conservation contexts: first, to pinpoint areas of high conservation value (biodiversity indicators), and second, to identify environmental change (Pearson 1994). In the former case, the indicator concept is based on the assumption that the presence of certain proxy taxa also captures a broad range of other organisms or conservation targets (Pearson & Cassola 1992, Carroll & Pearson 1998, Crisp et al. 1998, Duelli & Obrist 1998, Rodrigues et al. 1998, Tardif & DesGranges 1998, Lawler et al. 2003); thus, they can help in siting and designing reserves (Terborgh & Winter 1983). The second group can be subdivided further into indicators of environmental contaminants, habitat quality, and pop­ulation trends (Landres et al. 1988, Landres 1992). Obviously, effective indicators of environ-

mental change need to be sufficiently sensitive to human-caused disturbance in order to provide an early warning of decaying environmental conditions (Cairns 1986, Munn 1988, Frost et al. 1992), and their population trends should mirror those of other species sensitive to the same anthropogenic impacts (Caro & O’Doherty 1999). A growing body of literature has questioned the effectiveness of indicator groups for conservation purposes, especially those of vertebrates (e.g., Landres et al. 1988, Prendergast et al. 1993, Dobson et al. 1997, Andelman & Fagan 2000). Thus, it seems worth­while to analyze the performance of tropical birds as indicators in different conservation contexts and on different geographical scales, which here include the global level, the regional context of the Ecuadorian Chocó, and the local perspective of Playa de Oro. Hence, I will focus on birds as indicators of habitat quality as well as of biodiversity patterns.

Methods Collection of habitat and bird data The methods used for the mapping of habitats, vege­ tation structure, and human impacts are described on p. 35, Methods. The bird survey methods included mist netting, transect mapping, and non-stan­ dardized observation hours (p. 65-71, Meth­ods). Endemic and threatened species For the determination of endemic species I used Stattersfield et al. (1998: 199-203, 210-215) and, in addition, Ridgely & Greenfield (2001b:  63-68). Differences in the assignment of endemic species between the two publications are due to the following factors: (1) divergent treatment of taxonomy at the species/subspecies level; (2) deviation in the criteria defining an endemic taxon: ‘50  000  km2 historic breeding range’ criterion (Stattersfield et al. 1998: 1926) versus ‘mostly restricted to only one biogeo­ graphic area’ (Ridgely & Greenfield 2001b: 62-63); and (3) differences in the definitions of the ‘centers of endemism’. For the threat status, I exclusively employed lists based on the official IUCN threat categories sensu 179

IUCN (2001) and Gärdenfors et al. (2001), in particular BirdLife International (2000, 2004b) for the global level and Granizo et al. (2002) for the national level. Flagship and umbrella species Flagship species are charismatic animals that attract public attention and support. Successful candidates are often chosen on the basis of their decreasing popu­lation size or threat status (Dietz et al. 1994). In addition, they are usually rather large in size to better promote the conservation of extensive areas of natural habitat (Caro & O’Doherty 1999). In contrast to flagships, which need only be attractive and popular but not ecologically significant, umbrella species have to be ecologically important but not necessarily attractive to the public (Caro & O’Doherty 1999). Naturally, they should be large (Wicox 1984) because of the positive correlation between body size and area requirement (Brown 1995). Furthermore, to provide an effective protective shield for local biodiversity, they must have large ranges in comparison with sympatric species. In this way, the ranges of viable populations of the target species can encompass the area necessary to ensure the survival of other species with similar habitat requirements (Berger 1997). Using Playa de Oro and the Ecuadorian Chocó as examples, I discuss how useful these surrogate species are in achieving certain conservation goals. Life zone assemblages In northwestern Ecuador, many forest-dependent bird species clearly have a narrow niche width as regards climatic conditions, altitudinal range, vegeta­ tion types, and other ecological factors (e.g., interspecific competition and pathogens). Here, I define as ‘life zone specialists’ those forest- and forest-edgeinhabiting avian taxa that in Esmeraldas Province, Ecuador, occupy only one to three different life zones sensu Holdridge (1967). Most of these species have a strong indicator function regarding certain forest types, and many of them would quickly be in trouble if their main habitat were cleared or if their life zones shifted due to climate change. Thus, they are of potential importance for biologists and managers in directing conservation efforts, as the composition and completeness of these habitat assemblages might function as a surrogate for the integrity and quality of the associated forest types.

Ideally ‘life zone assemblages’ would be deter­ mined through intensive sampling of all forest hab­ itats in a defined geographic area, e.g., the coastal lowlands of Ecuador between sea level and the 900 m contour line. Associations of bird species with certain life zones could then be tested statistically. However, such comprehensive bird data are not available for western Ecuador, and therefore I had to base the assignments on my own and other workers’ field experience as well as on published records on avian habitat requirements and distributions (e.g., Ridgely & Greenfield 2001b). Consequently, the life zone assemblages presented here should be regarded as preliminary at best. Furthermore, I determined these indicator groups only for five life zones, as I did not have sufficient field experience in other regions of the western Ecuadorian lowlands. Very important for the determination of life zone assemblages was the exchange of information with P. Mena V., who has also carried out intensive field work in northwestern Ecuador. Together we studied a total of 18 localities at an elevational range of c. 5 to 550 m in Esmeraldas Province between Apr. 1995 and May 2001 (Fig. 40). The survey effort was different at each locality. Playa de Oro was by far the most intensively studied site, with > 27 km of sampled transects – almost half the total transect length. Some of the localities at the periphery of the study area were sampled in only a single transect or a few transects of c.  1000 to 1500 m. Apart from transect mapping, the principal survey method, mist netting was used at Playa de Oro and San Miguel. The life zones considered were tropical dry forest, tropical humid forest, tropical wet forest, the ‘lowermost base of the Andean foothills’ (cf.  p. 26, Life zones), and premontane pluvial forest. In north­ western Ecuador, tropical dry forest includes decid­ uous and semi-deciduous forest types close to the coast, which were not present in the studied sites. Likewise, in the case of premontane pluvial forest, only the lowermost 100-200  m of an altitudinal range between c.  350 and 1800  m were sampled until May 2001. Therefore, the assignment of birds to these life zones was based mainly on published accounts. However, since Nov. 2004, the author and P.  Mena V. studied at least nine additional sites in Esmeraldas and several more in Imbabura, Pichincha, Cotopaxi, and Guayas, between about 40 and 3600 m above sea level, thus widening the base of knowledge on the species composition in additional

hab­itats and ‘life zones’ and confirming the general com­position of life zone assemblages presented ­here. Assessment of the conservation value of MNT1 and MNT2 To demonstrate how the conservation value of study sites can be assessed by analyzing the composition of their avian communities, I used the transect-mapping

data of MNT1 and MNT2 as an example (Appendices 12a and 12b; Table 52). In particular, I looked at the species’ habitat preferences as well as at the presence/absence of threatened and endemic bird taxa. Furthermore, I applied the ‘bird community index’ approach described by Bradford et al. (1998) and Canterbury et al. (2000), which analyzes the entire avian community as an indicator of forest condition at the local level. The principal assumption 181

of the method is that individual habitat assemblages of birds can indicate only the particular resource condition defining them, whereas ecological status and biotic integrity should be evaluated on the basis of multiple habitat assemblages. For example, largescale timber harvest often results in the loss of bird taxa requiring mature stands or continuous forest as well as in the invasion by species characteristic of earlier successional stages and forest edges. Thus, the forest bird community index BCIforest should contrast disturbance-sensitive forest taxa against disturbancetolerant species. I used the formula BCIforest = ln (∑ SF + l) – ln (∑ SOC + ∑ SFE + l) with SF representing forest-dependent species in the sample [not only mature forest taxa as in Canter­bury et al. (2000)], SOC open-country birds, and SFE forest-edge species. I calculated the BCIforest for MNT1 and MNT2, using the presence /absence data gathered in the transect-mapping study. I employed the general hab­ itat category of each species (Appendix 8). Non-core taxa (sensu Remsen 1994), habitat generalists, and species depending on open water, large rivers, and fast-flowing streams were omitted. Data analysis Multivariate analysis Ecological problems, like habitat selection by birds, naturally involve numerous environmental variables, gradients, and numerous species and individuals (Gauch 1982). Thus, community data are clearly mul­tivariate and should be analyzed with correspond­ ing methods, whereas univariate or bivariate sta­tistics would be appropriate if only one or two environ­ mental gradients existed (McCune & Grace 2002). Multivariate analyses provide a relatively objective and straightforward summary of complex in­for­ma­ tion and thus contribute to hypothesis generation by leading ecologists to the discovery of structure in the data (Gauch 1982). Here, I considered the standardized mist-netting and transect-mapping data gathered in the hab­itat mosaics at MNT1 and MNT2 (Appen­dices 12a and 12b). The data of both transects were pooled. In the case of mist netting, I omitted individuals that were recaptured within six hours to ensure that their ­habitat selection was not influenced by the locality at which they were previously released. Furthermore, to avoid uninterpretable noise in the data set, species

with less than three independent capture events had to be excluded. A total of 2545 captures of 87 species was considered. In the case of the transect-mapping data only near-belt records were taken into account because habitat characterization in the far belts was not detailed enough to permit meaningful testing for bird-habitat associations (p. 35f, Mapping of habitats, vegetation structure, and human impact). Again, species with less than three MTW records were omitted. In total, 2626 records of 114 species were valid. In both data sets bird abundances were logtransformed to reduce the influence of the most common species. Likewise, rare species, defined as those with relative abundances < 20% of the most frequently recorded birds, were down-weighted in relation to more abundant species in order to minimize an unduly high influence of eventual outliers, adding noise to the data sets. The nets (n = 136), which had a fixed position along the habitat gradients, were the sample units of the mist-netting study. They were, of course, not sta­ tisti­cally independent of each other. However, in­de­ pendence of sample units is not a prerequisite for the use of ordination techniques, such as correspondence analysis or canonical correspondence analysis (ter Braak & Smilauer 2002), as long as interpretations are of a descriptive nature. Gradients were measured from the center of each net. Thus the true position of captures had an error of up to ± 3.3 m relative to the environmental factor. In reality the error was greater, up to an estimated ± 9 m, because the dis­ tances between net-centers and environmental factors were measured on the maps and not in the field. In the transect-mapping study, sample units were the 25 x 25-m main belt plots (n = 94). These plots were obviously not statistically independent either. Gradients were measured from the centers of the plots. As a consequence, the true position of the birds had an error of up to ± 17.7 m (= half-diagonal of the plot) relative to the environmental factor. Due to the reasons mentioned above, the real error was probably greater, up to an estimated ± 24 m. For direct multivariate analyses I considered the following environmental variables: – Main habitat types (cf.  p. 45-54, Structural ­features of the main habitats of MNT1 and MNT2), i.e., open country (OC), young successional forest (ysF), and medium-age forest (magF), were used as binary ‘dummy’ variables, which are shown in some figures, but did not influence the ordination results.

– Distance to the nearest forest edge (D-F/OC) was measured as a linear gradient, with distances with­ in open country having negative signs and dis­ tances within forest positive signs. Forest birds that avoid open country as well as grassland and scrubland species that avoid forest or their edges should respond strongly to this variable. – Proximity to the nearest forest edge (P-F/OC) was expressed in positive metric scores, with sample units closer to the forest edge having higher positive values than those at greater distances, independently of the main habitat in which they were located. Forest-edge species that use the entire ecotone, in other words the outside as well as the inside portion of the forest border, are expected to respond positively to this variable. – Proximity to the river (P-R) was expressed in pos­ itive metric scores, with sample units closer to the river having higher values than those at greater distances. This environmental variable is important because human disturbance (including hunt­ ing pressure) decreases with increasing distance from navigable rivers. Furthermore, some bird taxa are more frequently encountered in river-edge vegetation than in any other habitat. – Proximity to the nearest water body (stream, artifi­ cial channel, etc.) within open country (P-waOC) was ex­pressed in positive metric scores. In single vari­able analyses (see below), I have used the ­distances to the water bodies instead (D-waOC). In extensively forested areas, like the Chocó ­re­gion, streams in open country are a surrogate habitat for river-edge species. Consequently, this variable might help to uncover corresponding habitat associations. – Proximity to nearest forest stream (P-strF) in pos­ itive metric scores. Some forest birds construct their nests above streams or in stream banks, and others forage preferably in their vicinity. These taxa may also show a close association with forest streams in survey data. – Proximity to nearest tree-fall gap within forest (P-tgF) in positive metric scores. Tree-fall gaps in­fluence the distribution pattern of certain forestdwelling birds (e.g., Schemske & Brokaw 1981) and were thus considered here. – The combined foliage density of the midstory and canopy (COV-M+C) was expressed in cover scores according to Table  4. Thus, values between zero and eight were theoretically possible. In some graphics I used the uncovered portion of the mid-

story and canopy (UNC-M+C), which was ob­ tained by subtracting the combined cover from the maximum value of eight. I selected this variable because it was identified as the structural feature with the highest potential to differentiate between the three main habitat types (Chapter 3). All potential environmental variables were tested for colinearity by inspecting weighted correlation matrices generated in CANOCO (ter Braak & Smilauer 2002). If two or several variables showed high correlation coefficients (> 0.75) and/or elevated ‘in­ flation factors’ (IF > 20), only one of them was used in the subsequent analyses. Finally, four variables were used for the mist-netting data and five for the MTW data. The importance of each of these vari­ ables was tested using CANOCO’s ‘forward selection tool’ and a Monte Carlo permutation test (Table 44). However, some omitted colinear variables, subjec­ tively judged to be important, were shown as supplementary (passive) variables in the ordination graphs. The following multivariate analyses were carried out: Detrended Correspondence Analysis (DCA). – A widely used indirect eigenanalysis-based ordination technique derived from Correspondence Analysis (CA; synonymous with Reciprocal Averaging, RA), that can be used if a strong gradient is expected (Hill & Gauch 1980). DCA performs detrending by di­ viding the first axis into segments and subsequently centering the second axis on zero in order to remove the ‘arch effect’, an artifact obtained in the CA and other ordination techniques (Gauch 1982, Pielou 1984, Digby & Kempton 1987). The first axis explains most of the variance of species data, and thus is the most worthwhile in interpretation. Analyses were carried out with the software package ­CANOCO (ter Braak & Smilauer 2002). Since bird species were the focus of interest, I used the scaling options ‘biplot scaling’ and ‘focus on species distance’. Output graphics were subsequently edited in CANODRAW (ter Braak & Smilauer 2002). Canonical Correspondence Analysis (CCA). – An ordination method for direct eigenanalysis-based gradient analysis that permits the interpretation of environmental correlations (ter Braak 1986, 1987; Jongman et al. 1987). The significance level of each environmental factor might be determined by Monte Carlo permutation tests (Table 44). The ordina­tion technique, like other correspondence analysis meth­ ods, assumes that species have unimodal distributions along environmental gradients (ter Braak & Prentice 183

Meaningful interpretation might be mostly obtained for the first two axes. here, i used ccas with single variables to demonstrate the effect of the most important environmental gradients. the software and scaling options employed were the same as for the dcas (see above). Detrended Canonical Correspondence Analysis (DCCA). – the detrended form of the cca was chosen to minimize the so-called ‘arch effect’, a mathematically intrinsic problem of the cca algorithm. since this arch effect was quite obvious, i decided to apply detrending by 2nd order polynomials, an option in canoco. the scaling options were the same as for the dcas (see above).

measured ecological distances. the method assumes that dissimilarity is monotonically related to ecological distance. calculations were carried out with the program pc-ord (Mccune & Mefford 1999). i used the recommended qualitative form of the sørensen similarity coefficient as distance measurement. the algorithm followed the methods developed by Kruskal (1964) and Mather (1976). the number of axes producing the lowest stress was determined through multiple runs with randomized data. that is, runs were started with random configuration and a total of 15 runs were carried out for each data set. this ‘dimensionality assessment’ resulted in a final configuration of more than 3 axes for the mistnetting sample and 2 axes in the transect-mapping data. determination of indicator species potential indicator species for the three main habitat types represented in the mosaic landscape of the río

Santiago drainage were determined on the basis of the mist-netting and transect-mapping data sets described in the previous chapters. The following meth­ ods were used: Two-way Indicator Species Analysis (TWINSPAN). – The most widely used program for classifying species and samples by phytosociologists and vegetation ecologists. The method is derived from Correspondence Analysis (CA) and is thus based on recip­ rocal averaging ordination (Hill 1979). The process of classification is hierarchical (Hill et al. 1975). First, samples are successively divided into categories. In a second step, species are divided into categories on the basis of the sample classification. The final result is an arranged data matrix, or ordered two-way table, of the occurrence of species and samples (Gauch 1982). Potential indicator species are those arranged near either end of the ordination axis by reciprocal averaging. They are assigned higher weights (positive or negative) than the other species, and recomputing further polarizes the ordination. Subsequently, the samples are divided into two clusters by breaking the ordination axis, usually near the middle. Species are then assessed in terms of their fidelity to each of the two clusters and classified in the group to which they show a high fidelity. This procedure is then repeated for each of the clusters; see Gauch (1982) and Legendre & Legendre (1998) for details. The ana­lyses were carried out using presence/absence as well as log-abundance data. Input parameters were set to default, with the exception of the maximum level of divisions, which was set to three because interpre­ tation of further divided clusters was judged to be meaningless. Indicator Value (IndVal). – A rather new approach, developed by Dufrêne & Legendre (1997), which assesses a species’s abundance in relation to its rela­tive frequency of occurrence in various groups of samples. Indicator species are the most characteristic taxa of each group (McGeoch & Chown 1998). ‘Asymmet­ rical indicators’ are rare species that are found only at one or a few sites in one habitat group and are present exclusively in that group. Their presence cannot be predicted for all sites representing appropriate habitat, but they nevertheless contribute to the habitat specificity. By contrast, ‘symmetrical indicators’ occupy all sites of their habitat group and are found only in that group. Their presence at all sites of the group can be predicted. The indicator value of each species is calculated as the product of its habitat specificity and fidelity; see Dufrêne & Legendre

(1997) and Legendre & Legendre (1998) for details. The statistical significance of the indicator index is evaluated through a randomization procedure. In contrast to TWINSPAN, the indicator value for a given species is independent of the relative abundances of the other taxa. The analyses were carried out for the main habitat types using the default ­settings. In the case of mist netting, 2616 captures of 135  species were taken into account. The cor­ responding transect-mapping data embraced 2694 main-belt records of 155  species. I computed 499 randomizations for significance levels < 0.05 and < 0.01, and 999 randomizations for a probability of ≤ 0.001. Other statistical methods For the comparison of the life zone assemblages, I determined the number of shared species using Es­ timateS 6.0b (Colwell 2001). Furthermore, I com­ puted two qualitative (incidence-based) similarity indices, Jaccard and Sørensen I, according to the equations in Magurran (1988: 95), using the same software. Assumed correlations between the body size of the birds and their IUCN threat categories on global and national levels were assessed with the nonparametric Spearman’s rank test (Conover 1980, Fowler & Cohen 1986), using SPSS software (SPSS 2003). The test for species threatened at the national level was one-tailed, as a strong positive correla­tion between variables was anticipated. However, for globally threatened taxa a two-tailed test had to be carried out. I employed Microsoft Excel (Microsoft 2001) for the generation of graphics other than those based on ordination techniques. In all tests, differences were regarded as significant at a proba­ bility level of P < 0.05.

Results Endemic species Of the 336 bird species recorded in Playa de Oro until Nov. 2004, 13.1% (n = 44) are listed as endem­ ic taxa by Stattersfield et al. (1998) and/or Ridgely & Greenfield (2001b) (Table 45). According to Stattersfield et al. (1998), 24 species of Playa de Oro’s avifauna are endemic to the ‘Chocó Endemic Bird Area (EBA)’, and Ridgely & Greenfield (2001b) listed eight additional taxa as endemic to the ‘Chocó lowlands’. Stattersfield et al. (1998) regarded two species as endemic to the ‘Tumbesian EBA’, while Ridgely & Greenfield (2001b) cata­ 185

Transect-mapping (MTW) study e (number of birds recorded)

Standardized mist-netting and MTW surveys of transect MNT1: number of birds captured/recorded per species, type of record, and breeding/non-breeding status in the transect area. List of the 268 bird species recorded between Aug. 1995 and Mar. 1998 in the area of transects MNT1 (Fig.  5) and MNT2 (Fig. 8). All landbird species recorded during standardized and non-standardized surveys within 100 m of the transects were included. Lurocalis semitorquatus was present at both transects; however, the species was systematically overlooked and misidentified, and thus could not be included in the analysis (cf. Appendix 6, Nyctiphrynus rosenbergi). Most waterbirds, like frigatebirds, cormorants, ducks, herons, and gulls, followed the course of the Río Santiago on passage, and thus were not included because trees and shrubs obstructed the view of the river from any position on the transects. Only the heron Butorides striata was observed once at the backwater pond in the first section of MNT1, and the sandpiper Actitis macularius was sometimes heard from the start sections of both transects, which is why the latter two species were included. Species nesting within a radius of about 100 m from the transect during the study period were defined as breeding species of the transect area. By this definition the transect area of MNT1 was c. 15.6 ha. Larger species nesting outside the area were also counted as breeding species when their territories or home ranges obviously covered at least a part of the transect area. Abbreviations used: (a) species recorded: + = recorded in the transect area of MNT1; – = not recorded in the transect area of MNT1; exclusively recorded in the area of MNT2; (b)  type of record: for species exclusively recorded during non-standardized surveys; vi = visual observation; au = acoustical record; tr = tape recording; mn= mist-netted; (c) status (resident/seasonal status): br = breeding species in the transect area; breeding either confirmed or suspected; nbv = non-breeding visitor; used here for stragglers, foraging visitors, and short-distance migrants; NN-mi = Nearctic-Neotropical migrant; mi = migrant of other origin; i.e., intraNeotropical migrants and others; (d) mist-netting surveys (cf. Chapter 4): MNT1/I, MNT1/II, and MNT1/III = mist-netting surveys; MNT1/I-III = complete standardized mist-netting study; CAP1 = sum of first captures and recaptures mist-netted for the first time in the corresponding survey; CAP2 = sum of first captures and all types of recaptures; ∑Fc2 = sum of birds captured for the first time in the standardized study, excluding all types of recaptures; note: the total number of individuals captured might be slightly smaller than indicated by the sum of first captures, because not all species and individuals could be marked permanently; ∑CAP2 = sum of all captures, including recaptures; (e) MTW study (cf. Chapter 4): MNT1/1, MNT1/2, MNT1/3, and MNT1/4 = MTW surveys; ∑MNT1/1-4 = sum of all MTW surveys; note: the number of birds recorded includes repeated records of the same individuals and, therefore, can be considerably higher than the number of individuals present in the transect area.

Transect-mapping (MTW) study e (number of birds recorded) MNT2/1 MNT2/2 MNT2/3 MNT2/4 ∑MNT2/1-4

Standardized mist-netting and MTW surveys of transect MNT2: number of birds captured/recorded per species, type of record, and breeding/non-breeding status in the transect area. List of the 268 bird species recorded between Aug. 1995 and Mar. 1998 in the area of transects MNT1 (Fig. 5) and MNT2 (Fig. 8). See Appendix 12a for details on which species were excluded from the analysis and on the meaning of the abbreviations used. The only difference between the meaning of the abbreviations described in Appendix 12a and their meaning in the list presented below is that here all data refer to the conditions encountered in the transect area of MNT2 (c. 14.1 ha) and not MNT1.

MTW-study: detection threshold distance, abundance, population density, and biomass of the bird community in the transect area of MnT1. The detection threshold distances and effective detection areas are shown for all 268 bird species recorded between Aug. 1995 and Mar. 1998 within 100 m of the transects MnT1 and MnT2 (see Appendix  12a for details). For species recorded only in the transect area of MnT2, the values are stated in ‘[…]’ brackets. The population data are shown exclusively for the 162 species recorded in the MTW study of MnT1 between Feb. and nov. 1997. The results may not be representative for other areas of playa de Oro, even where similar habitat is present (e.g., continuous terra firme forest), and should be regarded as preliminary. Whenever i assumed that abundance, population density, and biomass density were considerably overestimated due to methodological biases or small sample size, the results are written in italics. Abbreviations used and explanations: (a) body mass: here, i used the mean values for unsexed samples (cf. Appendices 9 and 11); (b) average detection threshold distance (Ave. dTd): estimated mean perpendicular distance from the transect for which as many individuals of a certain species are detected beyond as are missed within; approximately the distance at which the loudest common sounds emitted by a bird species first become audible to an experienced observer under average environmental conditions (meteorological and topographical conditions, level of background noise, etc.); in general, the dTds stated here refer to the main habitat of each species, e.g., wet tropical forest in the case of forest species and semi-open country in the case of non-forest species; for species usually not detected by voice but visually (compare column ‘type of record’ in Appendix 6), i used a corresponding estimate of a ‘visual’ dTd, which was explicitly adapted to the environmental conditions of the transect areas of MnT1 and MnT2; i.e., the visual dTd for the Cathartidae was greater for MnT1 than for MnT2 (200 vs. 150 m, respectively), due to the fact that the landscape at the former transect was more open than at the latter, so that large soaring birds could be recorded there at a greater distance; (c) effective detection threshold distance (eff. dTd): the probability of detecting territories that are located at the periphery of the detection area of a transect increases with the number of MTW surveys carried out; therefore, the effective dTd increases accordingly; in the case of MnT1, the effective dTd was obtained by adding 30.5 % to the value of the average dTd (see p. 113 for details); the same percentage was used for species for which the calculation was founded on the number of displaying males, because their number was determined on the basis of four complete MTW surveys; thus, i assumed that the relationship between average dTd and effective dTd would be similar as in species establishing territories in pairs or family groups; for species that could not be analyzed in units of territories or displaying males, the effective dTd is identical to the average dTd and, for that reason, was not stated for them; (d) effective detection area (eff. dA): the area effectively surveyed for each species in the complete MTW-study, calculated as the product of twice the effective dTd (or the ‘average dTd’ for species that could not be analyzed in units of territories or displaying males) and the transect length (here 625 m); the product was divided by 10 000 in order to obtain the result in ‘hectares’; (e) number of territories (no. terr.): for species establishing and vocally advertising territories in pairs or family groups, the number of territories was determined by putting each record on a map; records obtained in different transect sections but during the same sample and observations of intra-specific territorial disputes, as well as the accumulation of records obtained during different MTW samples, facilitated the determination of the tentative limits between territories and their number; territories located at the ends of the transect were counted in 1/4-fractions of one territory (e.g., 0.25, 0.50, and 0.75 territories), depending on their relative size and position; likewise, territories much larger than the ‘effective detection area’ were also counted in 1/4-fractions of one territory; (f ) number of displaying males (no. displ. MM): for species of which the males establish and vocally advertise display territories (e.g., Lophotriccus pileatus) or leks (e.g., some pipridae) in order to attract females, i used the maximum number of displaying males recorded during single MTW samples at the lek sites or in display territories for the calculation of the population data; for these species all records of females, which in contrast to the males are basically silent, were ignored; for species of which individuals of both sexes vocalize frequently also apart from leks (e.g., hummingbirds), as well as for species that are usually silent, i used other methods (see below); (g) units per kilometer transect (Units/km trans.): number of territories or displaying males per kilometer transect; (h) units per km2 (Units/km2): number of territories or displaying males per square kilometer; calculated by multiplying the effective detection area’s fraction of one square kilometer by the number of territories or the number of displaying males recorded; (i) units per transect area (Units/trans. area): number of territories or

MTW-study: within-habitat abundance, population density, and available area per territory of the bird community in the transect area of MNT1. In contrast to Appendix 18a, the population data presented here refer exclusively to those portions of the transect area that actually contained the appropriate habitat for each species, in order to gain a better impression of the abundance and population density the species may reach in comparable homogeneous habitat. For species that occupied rather broad ecological niches, and therefore were present in the entire transect area, the population data are the same as in the previous appendix. The detection threshold distances, within-habitat length, and effective detection areas within habitat are shown for all 268 bird species recorded between Aug. 1995 and Mar. 1998 within 100 m of the transects MNT1 and MNT2 (cf. Appendix 12a). For species recorded only in the transect area of MNT2, the values are stated in ‘[…]’ brackets. Population data are shown exclusively for the 162 species recorded in the MTW study of MNT1 between Feb. and Nov. 1997. It is likely that such high population densities as calculated here for some species may be reached only locally in ideal habitat. The results may not be representative for other areas of Playa de Oro, even where similar habitat is present (e.g., continuous terra firme forest). Furthermore, the total number of territories or individuals recorded was often small and, in some cases, the ‘within-habitat detection area’ was very small in relation to the expected territory size of the species. In other words, the results have to be regarded as preliminary and should be interpreted with caution. Whenever I assumed that the within-habitat abundance or population density were considerably overestimated due to methodological biases or small sample size, the results are written in italics. Abbreviations used and explanations: (a) average detection threshold distance (Ave. DTD): see Appendix 18a; (b) effective detection threshold distance (Eff. DTD): see Appendix 18a; (c) within-habitat transect length (WiHab TraLen): estimated length of the portion of the transect that actually contained appropriate habitat for the species; the total length of transect MNT1 was 625 m; (d) effective detection area within habitat (Eff. DA WiHab): the area effectively surveyed within the habitat of each species in the complete MTW study, calculated as the product of twice the effective DTD (or the ‘average DTD’ for species that could not be analyzed in units of territories or displaying males) and the within-habitat transect length; the product was divided by 10 000 in order to obtain the result in ‘hectares’; (e) number of territories (No. terr.): see Appendix 18a; (f ) number of displaying males (No. displ. MM): see Appendix 18a; (g) units per kilometer transect within habitat (Units/km WiHab): number of territories or displaying males per kilometer transect within the habitat of the species; (h) units per km2 within habitat (Units/km2 WiHab): number of territories or displaying males per square kilometer within the habitat of the species; (i) individuals per unit (Ind./unit): see Appendix 18a; (j) maximum number of individuals (Max. no. ind.): see Appendix 18a; (k) average number of individuals (Ave. no. ind.): see Appendix 18a; (l) number of individuals per km transect within habitat (No. ind./km WiHab): the number of individuals per kilometer transect within the habitat of the species, either the maximum or average number of individuals, depending on the species or bird group (cf. Appendix 18a); (m) number of individuals per km2 within habitat (No. ind./km2 WiHab): absolute population density within an area of one square kilometer within the habitat of the species; (n) available area per territory (Available area/terr.): in general, this area is the sum of the size of the home ranges, which include the territories, and the size of the unoccupied portion of the detection area within the habitat; for species that occupied 100% of the detection area within the habitat, this area is a reasonably good estimate for the mean territory size; for species that occupied less than 100% of the detection area within the habitat, the territory size may be considerably smaller than indicated here. See p. 110-115, Estimation of population densities on the basis of transect-mapping data, for further details on the methodology used for the calculation of the population data and p. 164-166, How real are the modeled community data based on transect mapping?, on identified biases.

Biomass p density [g/km2]

MTW-study: detection threshold distance, abundance, population density, and biomass of the bird community in the transect area of MnT2. The detection threshold distances and effective detection areas are shown for all 268 bird species recorded between Aug. 1995 and Mar. 1998 within 100 m of the transects MnT1 and MnT2 (see Appendix 12b for details). For species recorded only in the transect area of MnT1, the values are stated in ‘[…]’ brackets. The population data are shown exclusively for the 144 species recorded in the MTW study of MnT2 between Mar. and nov. 1997. The results may not be representative for other areas of playa de Oro, even where similar habitat is present (e.g., continuous terra firme forest), and should be regarded as preliminary. Whenever i assumed that abundance, population density, and biomass density were considerably overestimated due to methodological biases or small sample size, the results are written in italics. Abbreviations used and explanations: (a) body mass: see Appendix 18a; (b) average detection threshold distance (Ave. dTd): see Appendix 18a; (c) effective detection threshold distance (eff. dTd): the effective dTd for MnT2 was obtained by adding 30.9 % to the value of the average dTd; see p. 113 for details; (d) effective detection area (eff. dA): the area effectively surveyed for each species in the complete MTW study, calculated as the product of twice the effective dTd (or the ‘average dTd’ for species that could not be analyzed in units of territories or displaying males) and the transect length (here 550 m); the product was divided by 10 000 in order to obtain the result in ‘hectares’; (e) number of territories (no. terr.): see Appendix 18a; (f ) number of displaying males (no. displ. MM): see Appendix 18a; (g) units per kilometer transect (Units/km trans.): see Appendix 18a; (h) units per km2 (Units/ km2): see Appendix 18a; (i) units per transect area (Units/trans. area): the transect area of MnT2 was 14.1 ha and is shown in Figure 8; cf. Appendix 18a; (j) individuals per unit (ind./unit): see Appendix 18a; (k) maximum number of individuals (Max. no. ind.): see Appendix 18a; (l) average number of individuals (Ave. no. ind.): see Appendix 18a; (m) number of individuals per km transect (no. ind./km): see Appendix 18a; (n) number of individuals per km2 (no. ind./ km2): see Appendix 18a; (o) number of individuals per transect area (no. ind./trans. area): see Appendix 18a; (p) biomass density: see Appendix 18a. See p. 110115, estimation of population densities on the basis of transect-mapping data, for further details on the methodology used for the calculation of the population data and p. 164-166, How real area the modeled community data based on transect mapping?, on identified biases.

MTW-study: within-habitat abundance, population density, and available area per territory of the bird community in the transect area of MnT2. in contrast to Appendix 19A the population data presented here refer exclusively to those portions of the transect area that actually contained the appropriate habitat for the species, in order to gain a better impression of the abundance and population density the species may reach in comparable homogeneous habitat. For species that occupied rather broad ecological niches, and therefore were present in the entire transect area, the population data are the same as in the previous appendix. The detection threshold distances, within-habitat length, and effective detection areas within habitat are shown for all 268 bird species recorded between Aug. 1995 and Mar. 1998 within 100 m of the transects MnT1 and MnT2 (see Appendix 12b for details). For species recorded only in the transect area of MnT1, the values are stated in ‘[…]’ brackets. population data are shown exclusively for the 144 species recorded in the MTW study of MnT2 between Mar. and nov. 1997. it is likely that such high population densities as calculated here for some species may be reached only locally in ideal habitat. The results may not be representative for other areas of playa de Oro, even where similar habitat is present (e.g., continuous terra firme forest). Furthermore, the total number of territories or individuals recorded was often small and, in some cases, the ‘within-habitat detection area’ was very small in relation to the expected territory size of the species. in other words, the results have to be regarded as preliminary and should be interpreted with caution. Whenever i assumed that the withinhabitat abundance or population density were considerably overestimated due to methodological biases or small sample size, the results are written in italics. Abbreviations used and explanations: (a) average detection threshold distance (Ave. dTd): see Appendix 18a; (b) effective detection threshold distance (eff. dTd): see Appendix 18a; (c) within-habitat transect length (WiHab TraLen): estimated length of the portion of the transect that actually contained appropriate habitat for the species; the total length of transect MnT2 was 550 m; (d) effective detection area within habitat (eff. dA WiHab): see Appendix 18b; (e) number of territories (no. terr.): see Appendix 18a; (f ) number of displaying males (no. displ. MM): see Appendix 18a; (g) units per kilometer transect within habitat (Units/km WiHab): see Appendix 18b; (h) units per km2 within habitat (Units/km2 WiHab): see Appendix 18b; (i) individuals per unit (ind./unit): see Appendix 18a; (j) maximum number of individuals (Max. no. ind.): see Appendix 18a; (k) average number of individuals (Ave. no. ind.): see Appendix 18a; (l) number of individuals per km transect within habitat (no. ind./km WiHab): see Appendix 18b; (m) number of individuals per km2 within habitat (no. ind./ km2 WiHab): see Appendix 18b; (n) available area per territory (Available area/terr.): see Appendix 18b. See p. 110-115, estimation of population densities on the basis of transect-mapping data, for further details on the methodology used for the calculation of the population data and p. 164-166, How real are the modeled community data based on transect mapping?, on identified biases.

Schriftleitung / Editor Karl-L. Schuchmann Zoologisches Forschungsmuseum Alexander Koenig (ZFMK) Ornithologie Adenauerallee 160 D-53113 Bonn, Germany Email: [email protected] Die Reihe Bonner zoologische Monographien (BZM) erscheint seit 1971 in regelmäßiger Folge. Publiziert werden Originalbeiträge in englischer Sprache. Die BZM nehmen vor allem solche ­Arbeiten auf, die zu umfangreich sind, um in der Zeitschrift Bonn ­zoologiCAL BULLETIN zu ­erscheinen. Schwerpunkte der BZM sind: Systematik, Taxonomie, Biogeographie, Anatomie und Evolutionsbiologie. ­Alle eingereichten Manuskripte werden begutachtet. Autoren werden gebeten, sich vor Manuskriptvorlage mit dem Schriftleiter in Verbindung zu setzen. Erwerb der BZM: Bibliothek, Zoologisches Forschungsmuseum Alexander Koenig (ZFMK), Adenauer­allee 160, D-53113 Bonn, Germany, Kontakt: d.steinebach. [email protected]. The peer-reviewed series Bonner Zoologische Monographien (BZM) has existed since 1971. The BZM consist of original zoology papers too long for inclusion in our institute’s journal Bonn ­zoologiCAL BULLETIN. Preferred manuscript topics are: systematics, taxonomy, biogeography, ­anatomy, and evolutionary biology. Manuscripts must be in American English. Authors are requested to contact the ­editor prior to manuscript submittal.
