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. -

[email protected] Abstract. Hummingbirds are one of the most diverse families of birds and the phylogenetic relationships within the group have recently begun to be studied with molecular data. Most of these studies have focused on the higher level classification within the family, and now it is necessary to study the relationships between and within genera using a similar approach. Here, we investigated the taxonomic status of the genus Hylocharis, a member of the Emeralds complex, whose relationships with other genera are unclear; we also investigated the existence of the Basilinna genus. We obtained sequences of mitochondrial (ND2: 537 bp) and nuclear genes (AK-5 intron: 535 bp, and c-mos: 572 bp) for 6 of the 8 currently recognized species and outgroups. -

Heather Levy FSU EAOS Honors Thesis Using a Call-Response Occupancy Survey with Brown-headed Nuthatches (Sitta pusilla) to Evaluate the Biological Species Concept Abstract The status of the endangered Bahama Nuthatch (Sitta insularis) as an independent species is being debated. The Bahama Nuthatch currently is listed as a subspecies of the Brown-headed Nuthatch (Sitta pusilla), even though the two differ in morphology, song, genetic characteristics, and range. According to the biological species concept, if two populations of the same species are unable to vocally recognize one another, then the two populations would not be able to interbreed, inferring two distinct species. Birds generally react more aggressively to vocalizations of conspecifics, or of the same species, than those of non-predatory heterospecifics, or of a different species, because two members of one species are in closer competition for mates, resources, and territories. In this study, I used a call-response occupancy survey at St. Marks National Wildlife Refuge to determine if using playback increased detection probabilities of Brown-headed Nuthatches. -

Introduction It well known that Anegada has globally important biodiversity. Indeed, biodiversity is the basis for most livelihoods; supporting fisheries and leading to the attractiveness that is such a draw to visitors. Over the last three years (2003-2006), a project was undertaken on Anegada with a wide range of activities focussing towards this Biodiversity Action Plan. From the outset it was known that the island hosts a globally important coral reef system, regionally significant populations of marine turtles, is of regional importance to birds and supports globally important endemic plants. The project arose following the encouragement of Anegada community members and subsequent extensive consultation between Dr. Godley (University of Exeter) and heads of BVI Conservation and Fisheries Department (CFD) and BVI National Parks Trust (NPT) who requested that funding be sourced for a project which: 1. Allowed the coastal biodiversity of Anegada to be assessed; 2. -

Field Guides Tour Report Thanksgiving in Jamaica 2019 Nov 24, 2019 to Nov 30, 2019 Cory Gregory & Dwane Swaby For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. Jamaica has such a long list of amazingly beautiful and colorful birds that it's hard to pick a favorite. Close to the top of the list however surely was this Jamaican Spindalis, a species only found in Jamaica. Photo by guide Cory Gregory. Sitting between South America and Cuba, the Caribbean nation of Jamaica was a fantastic place for us to enjoy the warm weather, the plethora of unique and fascinating birds, the relaxed lifestyle, and escaping the holiday hustle and bustle. With the birdy and historical Green Castle Estate as our home base, we made a variety of daytrips and had the luxury of returning back to the same place every night! Our day trips took us to a variety of birding hotspots and between them all, we saw a vast majority of the avifauna that this island nation has to offer. Even in driving from Montego Bay to Green Castle on our first day, we were surrounded with attention-grabbing species like Magnificent Frigatebirds gliding overhead, Zenaida Doves sitting on the wires, and even a small gathering of the rare West Indian Whistling-Ducks in Discovery Bay! Our first day at Green Castle was our first foray into the forests and we quickly connected with a fun collection of endemic species like the showy Streamertail, Jamaican Woodpecker, Sad Flycatcher, White-chinned Thrush, Jamaican Spindalis, Orangequit, and many others. -

Testing Sustainable Forestry Methods in Puerto Rico
Herpetology Notes, volume 8: 141-148 (2015) (published online on 10 April 2015) Testing sustainable forestry methods in Puerto Rico: Does the presence of the introduced timber tree Blue Mahoe, Talipariti elatum, affect the abundance of Anolis gundlachi? Norman Greenhawk Abstract. The island of Puerto Rico has one of the highest rates of regrowth of secondary forests largely due to abandonment of previously agricultural land. The study was aimed at determining the impact of the presence of Talipariti elatum, a timber species planted for forest enrichment, on the abundance of anoles at Las Casas de la Selva, a sustainable forestry project located in Patillas, Puerto Rico. The trees planted around 25 years ago are fast-growing and now dominate canopies where they were planted. Two areas, a control area of second-growth forest without T. elatum and an area within the T. elatum plantation, were surveyed over an 18 month period. The null hypothesis that anole abundance within the study areas is independent of the presence of T. elatum could not be rejected. The findings of this study may have implications when designing forest management practices where maintaining biodiversity is a goal. Keywords. Anolis gundlachi, Anolis stratulus, Puerto Rican herpetofauna, introduced species, forestry Introduction The secondary growth forest represents a significant resource base for the people of Puerto Rico, and, if At the time of Spanish colonization in 1508, nearly managed properly, an increase in suitable habitat one hundred percent of Puerto Rico was covered in for forest-dwelling herpetofauna. Depending on the forest (Wadsworth, 1950). As a result of forest clearing management methods used, human-altered agro- for agricultural and pastureland, ship building, and fuel forestry plantations have potential conservation wood, approximately one percent of the land surface value (Wunderle, 1999). -

Photo by Stephen J. Brenner NIGHTJAR DISTRIBUTION AND ABUNDANCE IN EASTERN NEBRASKA NONGAME BIRD PROGRAM 3 An important step in effectively conserving species of concern is defining their distributions and habitat associations. Eastern Whip-poor-will (Antrostomus vociferous; EWPW) and Chuck-will’s-widow (Antrostomus carolinensis; CWWI) are insectivorous birds whose breeding ranges cover much of eastern North America. Similar to other nightjars, both species are primarily active at night. EWPW and CWWI sing loudly between dusk and dark and consequently, are more often heard than seen. During the day, both species roost on or near the ground and each is cryptically-colored and are rarely detected by observers. Because of their behavior and life history, both species are infrequently and inconsistently detected by observers and by traditional avian monitoring programs such as the Breeding Bird Survey (BBS).
