Those who arrived in daylight had time to explore the phenomenal gardens, despite a rain storm. Day 1 - January 30 Optional day-trip to Carara National Park Guides Vernon and Frank offered an optional day trip to Carara National Park before the tour officially began and all tour participants took advantage of this special opportunity. As such, we are including the sightings from this day trip in the overall tour report. We departed the Hotel at 05:40 for the drive to the National Park. En route we stopped along the road to view a beautiful Turquoise-browed Motmot. -
2016 Checklist of Florida'a Birds
Artwork by Ann Marie Tavares 2016 Checklist of Florida’s Birds Prepared by Dr. Greg Schrott and Andy Wraithmell The Florida Fish and Wildlife Conservation Commission Florida’s wild places are home to an incredible diversity of birds. Over 500 native bird species or naturally occurring strays have been recorded in the state in historic times, and about 330 native species commonly occur here (four have gone extinct). A further 14 nonnative species are considered to have established large, stable populations in Florida. More than 70 natural community types support this diversity, from the pine flatwoods of Apalachicola National Forest, to the scrub communities of the Lake Wales Ridge, and the vast sawgrass marshes and mangrove swamps of Everglades National Park. Our natural areas harbor many bird species seen nowhere else in the United States such as the Florida Scrub-Jay, Mangrove Cuckoo, and Snail Kite. In addition, Florida’s birdlife changes with the cycle of the seasons. A constant turnover of breeding, wintering and migratory species provides new birding experiences throughout the year. To help you keep track of the spectacular range of birdlife the state has to offer, the Florida Fish and Wildlife Conservation Commission (FWC) has published this checklist. The first edition of Checklist of Florida’s Birds was prepared by Dr. Henry M. Stevenson in 1986. During his lifetime, Dr. Stevenson made many contributions to the field of ornithology, culminating with his writing The Birdlife of Florida with Bruce H. Anderson (1994). This book offers the most comprehensive information published on the lives of Florida’s birds. -
Anti-Predator Behavior in Birds: Reactions to Raptor Calls
Anti-predator behavior in Birds: Reactions to Raptor Calls Robin Elahi Department of Biology, Northeastern University _____________________________________________________________________________________ ABSTRACT Birds display a number of defense mechanisms against their predators, including camouflage, mobbing, fleeing, and aggregational behavior. I studied the responses of 32 bird species to songbird and raptor calls to see if birds displayed anti-predator behavior in response to raptor calls in comparison with songbird calls. One focus of my study was avian defensive strategies, namely flocking and concealment, so observations took into consideration different conditions: whether the bird was solitary or in a group, and whether it was exposed or hidden in vegetation. A previous study showed that crows could distinguish between raptor calls of their predators and non-predators, so I examined if birds specifically recognized resident raptors, or if they had a general response to resident and non-resident raptor calls. I also attempted to correlate bird size with reaction, specifically to see if smaller birds flew away more often than larger birds due to a greater perceived threat. For each bird or group of birds. I played a songbird call, followed by a raptor call, and timed the raptor call to see how long the bird stayed till it flew away. Birds flew away 27% of the time in response to raptor calls, and only 3% of the time to songbird calls (X² = 16.11, df = 1, n = 26). Birds did not distinguish among resident and non-resident raptor calls, and had nearly equal flight frequencies (X² = 0.48, df =3, n=40). Trends showed that solitary and exposed birds tended to fly more often than birds in groups and hidden birds. -

This latest instalment includes a new Scytalopus tapaculo and a new subspecies of Three-striped Warbler, reviews of species limits in Grey-necked Wood Rails and Pearly Parakeets and comprehensive molecular studies of Buff-throated Woodcreepers, Sierra Finches, Red-crowned Ant Tanagers and Siskins.

The Evolution of Nest Construction in Swallows (Hirundinidae) Is Associated with the Decrease of Clutch Size
© Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at Linzer biol. Beitr. 38/1 711-716 21.7.2006 The evolution of nest construction in swallows (Hirundinidae) is associated with the decrease of clutch size P. HENEBERG A b s t r a c t : Variability of the nest construction in swallows (Hirundinidae) is more diverse than in other families of oscine birds. I compared the nest-building behaviour with pooled data of clutch size and overall hatching success for 20 species of swallows. The clutch size was significantly higher in temperate cavity-adopting swallow species than in species using other nesting modes including species breeding in evolutionarily advanced mud nests (P<0.05) except of the burrow-excavating Bank Swallow. Decrease of the clutch size during the evolution of nest construction is not compensated by the increase of the overall hatching success. K e y w o r d s : Hirundinidae, nest construction, clutch size, evolution Birds use distinct methods to avoid nest-predation: active nest defence, nest camouflage and concealment or sheltered nesting. While large and powerful species prefer active nest-defence, swallows and martins usually prefer construction of sheltered nests (LLOYD 2004). The nests of swallows vary from natural cavities in trees and rocks, to self-exca- vated burrows to mud retorts and cups attached to vertical faces. Much attention has been devoted to the importance of controlling for phylogeny in com- parative tests (HARVEY & PAGEL 1991), including molecular phylogenetic studies of swallows (WINKLER & SHELDON 1993). Interactions between the nest-construction va- riability and the clutch size, however, had been ignored. -
