<\/a>The roseate tern is a\u00a0small bird (smaller than the common tern<\/a>) that flies very fast. The\u00a0reproductive adults have a black head, pinkish chest and orange legs. At the\u00a0beginning of the breeding season the beak is completely black, but after the\u00a0chicks are born the base becomes red. The reproductive period is between April\u00a0and July. The nests are located in areas protected by rocks or vegetation, but\u00a0the eggs (usually one or two) are laid directly on the ground. Their preferred\u00a0prey are small fish, especially mackerel<\/a>, garfish<\/a> and boar fish<\/a>. In the\u00a0Azores they\u00a0 commonly nest on all islands\u00a0(except Corvo where nesting is\u00a0sporadic). Nesting is most abundant in Flores, Graciosa and Santa Maria. In Europe it is a very rare species,\u00a0staying during Winter in the Caribbean and West Coast of Africa.\u00a0<\/span>This species is classified as “common breeding” in the Azores.
