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. -
Costa Rica Photo Journey: July 2017
Tropical Birding Trip Report Costa Rica Photo Journey: July 2017 Costa Rica Photo Journey 16-25 July 2017 Tour Leader: Jay Packer Many thanks to Deepak Ramineedi for allowing us to include his photos in this trip report. This Yellow-throated Toucan at Laguna del Lagarto wasn’t bothered at all by the rain. Note: Except where noted otherwise, all photos in this trip report were taken by Jay Packer. www.tropicalbirding.com +1- 409-515-9110 [email protected] Page 1 Tropical Birding Trip Report Costa Rica Photo Journey: July 2017 Introduction This Costa Rican photo journey featured visits to five regions of this small Central American country. We covered the moist Caribbean slope, Caribbean lowlands, dry forests on the Pacific slope, a large tropical river, and cloud forests of the volcanic highlands. The clients on the tour were a young couple and their 8-month old son. Given the considerations of traveling with an infant, the pace of the tour was relaxed and much of the photography was done at feeders or from the car. Even so, the diversity of Costa Rica was impressive as we encountered almost 200 species, photographing most of the targets that we hoped to see. Photographic highlights of the trip included stunning shots of toucan species in the rain, great hummingbird multiflash photography, a nesting pair of Turquoise-browed Motmots, Spectacled Owl, King Vultures, Resplendent Quetzal, very cooperative Great Green and Scarlet Macaws, Costa Rican Pygmy-Owl, and more. 16 July 2017 We began the tour with a drive out of San Jose to the well known Casa de Cope, west of Guápiles. -

Temperature tolerance and trophic dynamics were studied for three species (L. angustifrons, L. microlepis and L. mariae). Subsequently, several individuals of these three species were shipped to Heart of the Hills Research Station (HOHRS) in Ingram, Texas in 1975 (Rutledge and Lyons 1976 [cited by Schofield (2011) but not accessed for this report]). Also in 1975, Nile perch (L. niloticus) were transferred from Lake Turkana, Kenya, to HOHRS. All fishes were held in indoor, closed-circulating systems (Rutledge and Lyons 1976).” “From 1978 to 1985, Lates spp. was released into various Texas reservoirs (Howells and Garrett 1992 [cited by Schofield (2011) but not accessed for this report]). Almost 70,000 Lates spp. larvae were stocked into Victor Braunig (Bexar Co.), Coleto Creek (Goliad Co.) and Fairfield (Freestone Co.) reservoirs between 1978 and 1984. -

Communally Nesting Migratory Birds Create Ecological Hot-Spots in Tropical Australia
RESEARCH ARTICLE Communally Nesting Migratory Birds Create Ecological Hot-Spots in Tropical Australia Daniel J. D. Natusch1,2*, Jessica A. Lyons2, Gregory Brown1, Richard Shine1 1 School of Life and Environmental Sciences, University of Sydney, Sydney, New South Wales, Australia, 2 Resource Evaluation and Development, Bamaga, Queensland, Australia * [email protected] Abstract Large numbers of metallic starlings (Aplonis metallica) migrate annually from New Guinea to the rainforests of tropical Australia, where they nest communally in single emergent trees a11111 (up to 1,000 birds). These aggregations create dense and species-rich faunal “hot-spots”, attracting a diverse assemblage of local consumers that utilise this seasonal resource. The starlings nested primarily in poison-dart trees (Antiaris toxicaria) near the rainforest-wood- land boundary. Surveys underneath these colonies revealed that bird-derived nutrients massively increased densities of soil invertebrates and mammals (primarily wild pigs) beneath trees, year-round. Flying invertebrates, nocturnal birds, reptiles, and amphibians OPEN ACCESS congregated beneath the trees when starlings were nesting (the wet-season).

Oromia is the largest National Regional State of Ethiopia. Here we present the first comprehensive checklist of its birds. A total of 804 bird species has been recorded, 601 of them confirmed (443) or assumed (158) to be breeding birds. At least 561 are all-year residents (and 31 more potentially so), at least 73 are Afrotropical migrants and visitors (and 44 more potentially so), and 184 are Palaearctic migrants and visitors (and eight more potentially so). Three species are endemic to Oromia, 18 to Ethiopia and 43 to the Horn of Africa. 170 Oromia bird species are biome restricted: 57 to the Afrotropical Highlands biome, 95 to the Somali-Masai biome, and 18 to the Sudan-Guinea Savanna biome. -

Side-striped Jackal/Greater Galago/Roan Antelope/Blotched Genet Trip Summary This was our first ever fully comprehensive tour to Malawi and was quite simply a fantastic experience in all respects. For starters, many of the accommodations are of excellent quality and are also situated in prime birding locations with a large number of the area’s major birding targets found in close proximity. The food is generally very good and the stores and lodges are for the most part stocked with decent beer and a fair selection of South African wine. However, it is the habitat diversity that is largely what makes Malawi so good from a birding point of view. Even though it is a small country, this good variety of habitat, and infrastructure that allows access to these key zones, insures that the list of specials is long and attractive. Our tour was extremely successful in locating the vast majority of the region’s most wanted birds and highlights included Red-winged Francolin, White-backed Night Heron, African Cuckoo-Hawk, Western Banded Snake -

Only females incubated and brooded, but both adults built the nests, fed the nestlings, and removed their faecal sacs. -
