Elegant Tern (Thalasseus elegans) Science Article 1
abstract
The Elegant Tern (Sterna elegans) is widely distributed on the Paci?c coast of the Americas from British Columbia to Chile (Anonymous 1998, Burness et al. 1999). Despite this broad range, breeding is currently restricted to ?ve breeding colonies, two in the northern Gulf of California, Mexico, and three in coastal southern California (Collins et al. 1991,Burness et al. 1999). In winter and during migration these terns occur from Nayarit, Mexico to central Chile. During migration they may occur offshore as well as along the coast(Ridgely & Gwynne 1989, Collins 2006).
