Royal Tern, summer plumage, Thalasseus maximus maximus
We had great views of the roosting Royal Terns on Havana Beach on the 29th March 2017. This bird was in winter plumage but some of the others had virtually finished their moult into summer plumage. This race is found around coastal US to W Indies, Guianas, Brazil and they winter south to Argentina. Another race occurs in Africa. There are a few colonies of this species in Cuba and so ringed birds could be from here or mainland North America.
