Invasive House ( Rattus Rattus) and Brown Rats ( Rattus Norvegicus) Threaten the Viability of Red-Billed Tropicbird ( Phaethon Aethereus) in Abrolhos National Park, Brazil
Destruction of nests and predation by introduced species are among the main factors responsible for seabird declines. The red-billed tropicbird ( Phaethon aethereus) is a tropical, colonially nesting seabird whose distribution in Brazil is restricted to a small, isolated breeding colony located with...
