Two tropicbirds, a red-tailed and a white-tailed incubating their eggs.

When it comes to breeding site, Red-Tailed and White-Tailed Tropicbirds prefers Aldabra... The two species nest mainly on islets in Passe Femme, south of Picard. The collected information in the past 7 years' monitoring program helps to investigate the factors that influence breeding success and why they might be different for each species.
