ABSTRACT
Grand Bahama's pine forests are home to a unique but largely unstudied avifauna. No recent comprehensive survey has been conducted in these forests and little is known about the abundance and distribution of the island's pineland birds. This lack of information hinders efforts to monitor avian population trends, identify and protect areas important for bird conservation, and manage existing protected areas. We addressed this information gap by conducting line-transect surveys throughout the pinelands of Grand Bahama during April 2007 with the objective of providing updated information on the abundance and distribution of its resident birds. Of the species that rely primarily or exclusively on pine forest for breeding habitat, Olive-capped Warblers (Setophaga pilyophila) and Pine Warblers (S. pinus) were nearly ubiquitous in distribution and had large estimated population sizes. The remaining pineland species for which we estimated abundance-Hairy Woodpecker (Picoides villosus), Loggerhead Kingbird (Tyrannus caudifasciatus), and Bahama Warbler (S. flavescens)-were far less abundant and had very patchy distributions. We encountered too few La Sagra's Flycatchers (Myiarchus sagrae), Cuban Pewees (Contopus caribaeus), and Brown-headed Nuthatches (Sitta pusi/la) to estimate abundance. The scarcity of Brown-headed Nuthatches stood in stark contrast to their relative abundance in the late 1960s, and follow-up surveys for this species are of critical importance. We recommend additional surveys in the future, both to refine the findings presented here and to begin to generate estimates of population trends. Our results also suggest that the priority for conservation and management efforts should be those forest stands that support populations of Bahama Warblers and Brown-headed Nuthatches.
