Assessing Conservation Status of Resident and Migrant Birds on Hispaniola with Mist-Netting
Assessing conservation status of resident and migrant birds on Hispaniola with mist-netting John D. Lloyd, Christopher C. Rimmer and Kent P. McFarland Vermont Center for Ecostudies, Norwich, VT, United States ABSTRACT We analyzed temporal trends in mist-net capture rates of resident (n D 8) and overwintering Nearctic-Neotropical migrant (n D 3) bird species at two sites in montane broadleaf forest of the Sierra de Bahoruco, Dominican Republic, with the goal of providing quantitative information on population trends that could inform conservation assessments. We conducted sampling at least once annually during the winter months of January–March from 1997 to 2010. We found evidence of declines in capture rates for three resident species, including one species endemic to Hispaniola. Capture rate of Rufous-throated Solitaire (Myadestes genibarbis) declined by 3.9% per year (95% CL D 0%, 7.3%), Green-tailed Ground-Tanager (Microligea palustris) by 6.8% (95% CL D 3.9%, 8.8%), and Greater Antillean Bullfinch (Loxigilla violacea) by 4.9% (95% CL D 0.9%, 9.2%). Two rare and threatened endemics, Hispaniolan Highland-Tanager (Xenoligea montana) and Western Chat-Tanager (Calyptophilus tertius), showed statistically significant declines, but we have low confidence in these findings because trends were driven by exceptionally high capture rates in 1997 and varied between sites. Analyses that excluded data from 1997 revealed no trend in capture rate over the course of the study. We found no evidence of temporal trends in capture rates for any other residents or Nearctic-Neotropical migrants. We do not know the causes of the observed declines, nor can we conclude that these declines are not a purely Submitted 12 September 2015 local phenomenon. -

D. Ascanio Victor Emanuel Nature Tours The Dominican Republic April 14-21, 2012 Leaders: David Ascanio & Kate Wallace Photo composition. Bay-breasted Cuckoo. Photo: D. Ascanio This was our fifth consecutive Dominican Republic tour and what a way to celebrate it: with astonishing views of a pair of Hispaniolan Crossbill and a Bay-breasted Cuckoo scoped while perched on a open branch! The Hispaniola comprises two countries and two paleo-islands. Each of these paleo-islands (separated in the past by a sea channel) hosted unique endemic avifauna and, once joined together the gene exchange took place by birds dispersing into each of the other paleo-island. One would expect competition among species with similar niche, but instead many survived and gave to the Hispaniola an unique feature among the Antilles: it host two species of todies, a relictual population of a crossbill, two species of palm tanagers and an endemic family of birds: the Palmchat. This year we enjoyed mild rain that actually turned in or side as we experience early morning bird activity each moment it stopped raining no matter the time of the day. But, to bring back some of the memories of the trip a short paragraph follows for each day (extracted from my journal): 14 April 2012. Arrival to The Dominican Republic. -
Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

The Avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, Including Evidence for Long-Term Population Dynamics in Undisturbed Tropical Forest
Ben Freeman & Alexandra M. Class Freeman 30 Bull. B.O.C. 2014 134(1) The avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, including evidence for long-term population dynamics in undisturbed tropical forest Ben Freeman & Alexandra M. Class Freeman Received 27 July 2013 Summary.—We conducted ornithological feld work on Mt. Karimui and in the surrounding lowlands in 2011–12, a site frst surveyed for birds by J. Diamond in 1965. We report range extensions, elevational records and notes on poorly known species observed during our work. We also present a list with elevational distributions for the 271 species recorded in the Karimui region. Finally, we detail possible changes in species abundance and distribution that have occurred between Diamond’s feld work and our own. Most prominently, we suggest that Bicolored Mouse-warbler Crateroscelis nigrorufa might recently have colonised Mt. Karimui’s north-western ridge, a rare example of distributional change in an avian population inhabiting intact tropical forests. The island of New Guinea harbours a diverse, largely endemic avifauna (Beehler et al. 1986). However, ornithological studies are hampered by difculties of access, safety and cost. Consequently, many of its endemic birds remain poorly known, and feld workers continue to describe new taxa (Prat 2000, Beehler et al. 2007), report large range extensions (Freeman et al. 2013) and elucidate natural history (Dumbacher et al. 1992). Of necessity, avifaunal studies are usually based on short-term feld work. As a result, population dynamics are poorly known and limited to comparisons of diferent surveys or diferences noticeable over short timescales (Diamond 1971, Mack & Wright 1996). -

E-mail: [email protected] Abstract We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. We surveyed published studies on bird diets, and information on labels of museum specimens, compiling data on the contents of 5,221 stomachs. Eighteen samples (0.3%) presented evidence of predation on vertebrates. Our bibliographic survey also provided records of 203 passerine species preying upon vertebrates, mainly frogs and lizards. Our data suggest that vertebrate predation by passerines is relatively uncommon in the Neotropics and not characteristic of any family. On the other hand, although rare, the ability to prey on vertebrates seems to be widely distributed among Neotropical passerines, which may respond opportunistically to the stimulus of a potential food item. -
Wildlife Parasitology in Australia: Past, Present and Future
CSIRO PUBLISHING Australian Journal of Zoology, 2018, 66, 286–305 Review https://doi.org/10.1071/ZO19017 Wildlife parasitology in Australia: past, present and future David M. Spratt A,C and Ian Beveridge B AAustralian National Wildlife Collection, National Research Collections Australia, CSIRO, GPO Box 1700, Canberra, ACT 2601, Australia. BVeterinary Clinical Centre, Faculty of Veterinary and Agricultural Sciences, University of Melbourne, Werribee, Vic. 3030, Australia. CCorresponding author. Email: [email protected] Abstract. Wildlife parasitology is a highly diverse area of research encompassing many fields including taxonomy, ecology, pathology and epidemiology, and with participants from extremely disparate scientific fields. In addition, the organisms studied are highly dissimilar, ranging from platyhelminths, nematodes and acanthocephalans to insects, arachnids, crustaceans and protists. This review of the parasites of wildlife in Australia highlights the advances made to date, focussing on the work, interests and major findings of researchers over the years and identifies current significant gaps that exist in our understanding. The review is divided into three sections covering protist, helminth and arthropod parasites. The challenge to document the diversity of parasites in Australia continues at a traditional level but the advent of molecular methods has heightened the significance of this issue. Modern methods are providing an avenue for major advances in documenting and restructuring the phylogeny of protistan parasites in particular, while facilitating the recognition of species complexes in helminth taxa previously defined by traditional morphological methods. The life cycles, ecology and general biology of most parasites of wildlife in Australia are extremely poorly understood. While the phylogenetic origins of the Australian vertebrate fauna are complex, so too are the likely origins of their parasites, which do not necessarily mirror those of their hosts. -

Bird Abundances in Primary and Secondary Growths in Papua New Guinea: a Preliminary Assessment
Mongabay.com Open Access Journal - Tropical Conservation Science Vol.3 (4):373-388, 2010 Research Article Bird abundances in primary and secondary growths in Papua New Guinea: a preliminary assessment Kateřina Tvardíková1 1 Department of Zoology, Faculty of Biological Science, University of South Bohemia, Branišovská 31, CZ- 370 05 České Budějovice. Email: <[email protected] Abstract Papua New Guinea is the third largest remaining area of tropical forest after the Amazon and Congo basins. However, the growing intensity of large-scale slash-and-burn agriculture and logging call for conservation research to assess how local people´s traditional land-use practices result in conservation of local biodiversity, of which a species-rich and diverse component is the avian community. With this in mind, I conducted a preliminary survey of birds in small-scale secondary plots and in adjacent primary forest in Wanang Conservation Area in Papua New Guinea. I used mist-netting, point counts, and transect walks to compare the bird communities of 7-year-old secondary growth, and neighboring primary forest. The preliminary survey lasted 10 days and was conducted during the dry season (July) of 2008. I found no significant differences in summed bird abundances between forest types. However, species richness was higher in primary forest (98 species) than in secondary (78 species). The response of individual feeding guilds was also variable. Two habitats differed mainly in presence of canopy frugivores, which were more abundant (more than 80%) in primary than in secondary forests. A large difference (70%) was found also in understory and mid-story insectivores. Species occurring mainly in secondary forest were Hooded Butcherbird (Cracticus cassicus), Brown Oriole (Oriolus szalayi), and Helmeted Friarbird (Philemon buceroides). -
