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. -
Aquatic Birds at the Taiamã Ecological Station: Seasonal Variation of Community Structure and the Importance of Protected Areas in the Pantanal
24 Aquatic Birds at the Taiamã Ecological Station: Seasonal Variation of Community Structure and the Importance of Protected Areas in the Pantanal Daniel Luis Zanella Kantek1, Roselaine Carvalho de Melo2, Selma Samiko Miyazaki1, Welvis Felipe Fernandes Castilheiro2 & Manoel dos Santos Filho2 Recebido em 30/03/2020 – Aceito em 20/06/2020 1 Instituto Chico Mendes de Conservação da Biodiversidade, Estação Ecológica deTaiamã, Cáceres/MT, Brasil. <[email protected], [email protected]>. 2 Departamento de Ciências Biológicas, Programa de Pós-Graduação em Ciências Ambientais, Universidade do Estado de Mato Grosso, Cáceres/MT, Brasil. <[email protected], [email protected], [email protected]>. ABSTRACT – As the largest floodplain in the world, the Pantanal plays an important role in maintaining biological diversity. Taiamã Ecological Station (TES) is a protected area located in the north Pantanal; it is considered a relevant area for bird conservation. The species composition of these areas must be studied and known for the development of specific management plans. Besides, waterfowl are important in assessing quality and are highly sensitive to environmental changes. Thus, we investigated the aquatic bird composition at the TES and surrounding area and evaluated the richness and abundance levels among sites and the river level during one year of sampling. We performed a total sample effort of six campaigns, with four sites sampled: two at the TES and two in the surroundings. We identified a total of 45 aquatic bird species, divided into nine orders, 20 families and 36 genera. The large number of individuals observed in February 2012 can be related to a natural phenomenon that occurs in Pantanal, called ‘dequada’, which is associated with the processes of decomposition of submerged plant biomass at the beginning of the flood. -

Wild Patagonia & Central Chile
WILD PATAGONIA & CENTRAL CHILE: PUMAS, PENGUINS, CONDORS & MORE! NOVEMBER 1–18, 2019 Pumas simply rock! This year we enjoyed 9 different cats! Observing the antics of lovely Amber here and her impressive family of four cubs was certainly the highlight in Torres del Paine National Park — Photo: Andrew Whittaker LEADERS: ANDREW WHITTAKER & FERNANDO DIAZ LIST COMPILED BY: ANDREW WHITTAKER VICTOR EMANUEL NATURE TOURS, INC. 2525 WALLINGWOOD DRIVE, SUITE 1003 AUSTIN, TEXAS 78746 WWW.VENTBIRD.COM Sensational, phenomenal, outstanding Chile—no superlatives can ever adequately describe the amazing wildlife spectacles we enjoyed on this year’s tour to this breathtaking and friendly country! Stupendous world-class scenery abounded with a non-stop array of exciting and easy birding, fantastic endemics, and super mega Patagonian specialties. Also, as I promised from day one, everyone fell in love with Chile’s incredible array of large and colorful tapaculos; we enjoyed stellar views of all of the country’s 8 known species. Always enigmatic and confiding, the cute Chucao Tapaculo is in the Top 5 — Photo: Andrew Whittaker However, the icing on the cake of our tour was not birds but our simply amazing Puma encounters. Yet again we had another series of truly fabulous moments, even beating our previous record of 8 Pumas on the last day when I encountered a further 2 young Pumas on our way out of the park, making it an incredible 9 different Pumas! Our Puma sightings take some beating, as they have stood for the last three years at 6, 7, and 8. For sure none of us will ever forget the magical 45 minutes spent observing Amber meeting up with her four 1- year-old cubs as they joyfully greeted her return. -
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.

In both observations, a male and female rapidly raised their tails to a horizontal position and slowly returned them to a vertical hanging position. During these displays, both individuals simultaneously emitted loud calls approximately every 5 seconds, forming a duet. The first display lasted 30 minutes while the second lasted approximately 45 minutes. This `raised tail' behavior has been reported for several species of trogons during courtship and when mobbing a predator. Because there were no predators present during both observations, the described `raised tail' behavior was most likely a courtship display. -

Biodivers Conserv (2011) 20:3077–3100 DOI 10.1007/s10531-011-0118-9 REVIEW PAPER Effects of agriculture expansion and intensification on the vertebrate and invertebrate diversity in the Pampas of Argentina Diego Medan • Juan Pablo Torretta • Karina Hodara • Elba B. de la Fuente • Norberto H. Montaldo Received: 23 July 2010 / Accepted: 15 July 2011 / Published online: 24 July 2011 Ó Springer Science+Business Media B.V. 2011 Abstract In this paper we summarize for the first time the effects of agriculture expansion and intensification on animal diversity in the Pampas of Argentina and discuss research needs for biodiversity conservation in the area. The Pampas experienced little human intervention until the last decades of the 19th century. Agriculture expanded quickly during the 20th century, transforming grasslands into cropland and pasture lands and converting the landscape into a mosaic of natural fragments, agricultural fields, and linear habitats. In the 1980s, agriculture intensification and replacement of cattle grazing- cropping systems by continuous cropping promoted a renewed homogenisation of the most productive areas. Birds and carnivores were more strongly affected than rodents and insects, but responses varied within groups: (a) the geographic ranges and/or abundances of many native species were reduced, including those of carnivores, herbivores, and specialist species (grassland-adapted birds and rodents, and probably specialized pollinators), sometimes leading to regional extinction (birds and large carnivores), (b) other native species were unaffected (birds) or benefited (bird, rodent and possibly generalist pollinator and crop-associated insect species), (c) novel species were introduced, thus increasing species richness of most groups (26% of non-rodent mammals, 11.1% of rodents, 6.2% of birds, 0.8% of pollinators). -

Most favor open habitats, typically near water. Different species readily associate together, which can help with ID—compare size, shape, and behavior of an unfamiliar species with other species you know (see below); voice can also be useful. 2 1 5 3 3 3 4 4 7 6 6 Andean Avocet Recurvirostra andina 45–48cm N Andes.
