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. -
Final Recovery Plan Southwestern Willow Flycatcher (Empidonax Traillii Extimus)
Final Recovery Plan Southwestern Willow Flycatcher (Empidonax traillii extimus) August 2002 Prepared By Southwestern Willow Flycatcher Recovery Team Technical Subgroup For Region 2 U.S. Fish and Wildlife Service Albuquerque, New Mexico 87103 Approved: Date: Disclaimer Recovery Plans delineate reasonable actions that are believed to be required to recover and/or protect listed species. Plans are published by the U.S. Fish and Wildlife Service, sometimes prepared with the assistance of recovery teams, contractors, State agencies, and others. Objectives will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery plans do not necessarily represent the views nor the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service. They represent the official position of the U.S. Fish and Wildlife Service only after they have been signed by the Regional Director or Director as approved. Approved Recovery plans are subject to modification as dictated by new findings, changes in species status, and the completion of recovery tasks. Some of the techniques outlined for recovery efforts in this plan are completely new regarding this subspecies. Therefore, the cost and time estimates are approximations.

In Michigan in the west. The species was known in earlier they are generally more southern than Alder records in Michigan as "Alder Flycatcher" and Flycatchers, but the two species overlap in their "Traill's Flycatcher" (Barrows 1912, Wood breeding range throughout the SLP and NLP. 1951), and the early records did not distinguish Willow Flycatchers live in a variety of habitats between two distinct species, Willow Flycatcher of upland brush and lowland swamps, in and Alder Flycatcher. Only about 80-90% of overgrown uplands, dry marsh with unplowed birds of the two species can be distinguished in brushy grassy fields, old pasture land and morphology, but their behavior is distinct. thickets, shrubs along the edges of streams, and Willow Flycatchers give two song themes in wet thickets of willow, alder and buckthorn.

Of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds
B BIO VIEW Curator Notes From the Brink of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds In terms of conservation efforts, the Rio Grande Zoo is a rare breed in its own right, using its expertise to preserve and breed species whose numbers have dwindled to almost nothing both in the wild and in captivity. Recently, we took charge of a little over one-tenth of the entire world’s population of Socorro doves which have been officially extinct in the wild since 1978 and are now represented by only 100 genetically pure captive individuals that have been carefully preserved in European institutions. Of these 100 unique birds, 13 of them are now here at RGZ, making us the only holding facility in North America for this species and the beginning of this continent’s population for them. After spending a month in quarantine, the birds arrived safe and sound on November 18 from the Edinburgh and Paignton Zoos in England. Other doves have been kept in private aviaries in California, but have been hybridized with the closely related mourning dove, so are not genetically pure. History and Background Socorro doves were once common on Socorro Island, the largest of the four islands making up the Revillagigedo Archipelago in the East- ern Pacific ocean about 430 miles due west of Manzanillo, Mexico and 290 miles south of the tip of Baja, California. Although the doves were first described by 19th century American naturalist Andrew Jackson Grayson, virtually nothing is known about their breeding behavior in the wild. -

We include here information for those interested in the 2021 Field Guides Colombia: Bogota, the Magdalena Valley & Santa Marta tour: ¾ a general introduction to the tour ¾ a description of the birding areas to be visited on the tour ¾ an abbreviated daily itinerary with some indication of the nature of each day’s birding outings These additional materials will be made available to those who register for the tour: ¾ an annotated list of the birds recorded on a previous year’s Field Guides trip to the area, with comments by guide(s) on notable species or sightings (may be downloaded from our web site) ¾ a detailed information bulletin with important logistical information and answers to questions regarding accommodations, air arrangements, clothing, currency, customs and immigration, documents, health precautions, and personal items ¾ a reference list ¾ a Field Guides checklist for preparing for and keeping track of the birds we see on the tour ¾ after the conclusion of the tour, a list of birds seen on the tour 1900+ species.
