With 38% of earth’s ice free land surface covered by crops and pastures, studying and understanding the potential conservation value of these lands is critical for the future of conservation strategies, particularly in biodiversity conservation hotspots such as Central America. My research focused on understanding the contribution of different agricultural land uses and a forest fragment to bird conservation in a Costa Rican landscape. The study region is located at the heart of the Volcanica Central Talamanca Biological Corridor (VCTBC), a national conservation strategy aiming at reconnecting the Volcanica Central and the Talamanca Mountain Ranges. Chapter 1 and Chapter 2 are based on seven years of bird capture data produced by long-term mist-netting stations operating in eight different land uses, seven agricultural and a forest fragment. Chapter 1 comprises lessons learned during seven years of mist-netting efforts in eight land uses following a management intensity gradient. Chapter 2 focuses on bird community stability, stability understood as no changes from year to year in mean species richness and abundance of either the total population, or of resident and migratory species over a seven year period. Chapter 3 is based on an experimental study focusing on the effect of bird species in the suppression of the Coffee Berry Borer (Hypothenemus hampei), one of the most detrimental coffee pests worldwide. Results from our research highlights the importance of including agricultural land uses in biodiversity conservation planning. Agroforestry systems particularly showed potential for bird conservation in agricultural landscapes while fostering stable bird communities that are closer in composition to our reference forest fragment. Additionally, our results also showed that our landscape is capable of supporting bird species providing important pest control services. Finally, despite the value of agricultural land uses our results also highlight that our forest fragment fosters unique bird communities when compared to agricultural lands. Conservation planning at the landscape level should considered the uniqueness of these habitats and integrate efforts to conserve forests and managed agricultural lands for biodiversity conservation, particularly in these human-dominated landscapes. iii iv Acknowledgements I thank my major advisors Kerri Vierling and Fabrice DeClerck for every meeting, every informal conversation, every word of advice and for all the time you have spent guiding me in the right direction.

  • Antbird Guilds in the Lowland Caribbean Rainforest of Southeast Nicaragua1
    The Condor 102:7X4-794 0 The Cooper Ornithological Society 2000 ANTBIRD GUILDS IN THE LOWLAND CARIBBEAN RAINFOREST OF SOUTHEAST NICARAGUA1 MARTIN L. CODY Department of OrganismicBiology, Ecology and Evolution, Universityof California, Los Angeles, CA 90095-1606, e-mail: [email protected] Abstract. Some 20 speciesof antbirdsoccur in lowland Caribbeanrainforest in southeast Nicaragua where they form five distinct guilds on the basis of habitat preferences,foraging ecology, and foraging behavior. Three guilds are habitat-based,in Edge, Forest, and Gaps within forest; two are behaviorally distinct, with species of army ant followers and those foraging within mixed-species flocks. The guilds each contain 3-6 antbird species. Within guilds, species are segregatedby body size differences between member species, and in several guilds are evenly spaced on a logarithmic scale of body mass. Among guilds, the factors by which adjacent body sizes differ vary between 1.25 and 1.75. Body size differ- ences may be related to differences in preferred prey sizes, but are influenced also by the density of the vegetation in which each speciescustomarily forages. Resumen.

  • Bird Responses to Shade Coffee Production
    Animal Conservation (2004) 7, 169–179 C 2004 The Zoological Society of London. Printed in the United Kingdom DOI:10.1017/S1367943004001258 Bird responses to shade coffee production Cesar´ Tejeda-Cruz and William J. Sutherland Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, UK (Received 2 June 2003; accepted 16 October 2003) Abstract It has been documented that certain types of shade coffee plantations have both biodiversity levels similar to natural forest and high concentrations of wintering migratory bird species. These findings have triggered a campaign to promote shade coffee as a means of protecting Neotropical migratory birds. Bird censuses conducted in the El Triunfo Biosphere reserve in southern Mexico have confirmed that shade coffee plantations may have bird diversity levels similar to, or higher than, natural forest. However, coffee and forest differed in species composition. Species with a high sensitivity to disturbance were significantly more diverse and abundant in primary ecosystems. Neotropical migratory birds, granivorous and omnivorous species were more abundant in disturbed habitats. Insectivorous bird species were less abundant only in shaded monoculture. Foraging generalists and species that prefer the upper foraging stratum were more abundant in disturbed habitats, while a decline in low and middle strata foragers was found there. Findings suggests that shade coffee may be beneficial for generalist species (including several migratory species), but poor for forest specialists. Although shade coffee plantations may play an important role in maintaining local biodiversity, and as buffer areas for forest patches, promotion of shade coffee may lead to the transformation of forest into shade coffee, with the consequent loss of forest species.

DOI: http://dx.doi.org/10.15446/abc. v25n1.77442 ABSTRACT Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of specimens. We present results for three expeditions conducted in Santander (municipalities of Cimitarra, El Carmen de Chucurí, and Santa Barbara), Colombia, during 2018 to collect bird voucher specimens, quantifying the costs of obtaining such material. After a sampling effort of 1290 mist net hours and occasional collection using an airgun, we collected 300 bird voucher specimens, representing 117 species from 30 families.

Yet, it was still too early to experience the real explosion of bird song, which usually happens after dawn. Then, after 05:30 AM, the chorus started when a vocal Great Kiskadee broke the morning silence, followed by the scratchy notes of two Hoffmann´s Woodpeckers, a nesting pair of Inca Doves, the ascending and monotonous song of the Yellow-bellied Elaenia, and the cacophony of an (apparently!) engaged pair of Rufous-naped Wrens. This was indeed a warm welcome to magical Costa Rica! To complement the first morning of birding, two boreal migrants, Baltimore Orioles and a Tennessee Warbler, joined the bird feast just outside the hotel area. Broad-billed Motmot . Photo: D.

  • Diversity, Abundance and Seasonality of Birds in a Caribbean Pine Plantation and Native Broad-Leaved Forest at Trinidad, West Indies
    Bird Conservation International (1998) 8:67-87. © BirdLife International 1998 Diversity, abundance and seasonality of birds in a Caribbean pine plantation and native broad-leaved forest at Trinidad, West Indies FLOYD E. HAYES and ISHMAELANGELO SAMAD Summary Monoculture plantations of exotic Caribbean pine Finns caribaen have been planted extensively in many tropical countries, but little is known about the bird communities inhabiting them. From October 1995 to September 1996, we compared bird populations in a 37-ha stand of mature Caribbean pine forest (planted in 1972) with an adjacent, similar-sized stand of native broad-leaved forest at Mount Saint Benedict, Trinidad, West Indies. Ten censuses, each including 10 fixed-radius point counts (25 m radius, 10 minutes duration), were conducted simultaneously during different months of the year in each habitat. Both species richness and species diversity were significantly lower in the pine forest, but the overall abundance of individual birds did not differ between the two forests. Seasonal variation in bird populations was more pronounced in the pine forest, where fewer birds (and presumably food resources) were present during the dry season. The pine forest bird community was dominated by forest edge specialists and the native forest by forest interior specialists at both the individual and species levels. At the individual level, nectarivores, aerial foragers and understorey foragers were proportionately more common in the pine forest; insectivores and canopy foragers were more common in the native forest. At the species level, more aerial foragers occurred in the pine forest and more understorey foragers in the native forest. The diversity of bird communities in pine plantations may be promoted by increasing habitat heterogeneity.
