Population Estimates, Conservation Concerns, and Management of Tropicbirds in the Western Atlantic

摘要

Two species of trpicbirds (Phaethontidae) live in the Western North Atlantic. The White- tailed Tropicbrid of the region is an endemic race, Phaethon lepturns catesbyi, with approximately 5000 pairs. This is half the estimate made less than two decades ago. The Red-billed Tropicbird, P, aethereus, has Approximately 2000 pairs regionally and fewer than 8000 pairs globally. Neither species has been considered To be of conservation concern. We suggest that the Atlantic populations of Phaethon lepturus and the global Population of Phaethon aethereus be considered for appropriate conservation status listings reflecting their Rare and declining populations.
