About These Birds
European Roller
The European roller gets its name from the spectacular rolling and tumbling aerial displays performed by males during courtship. It is the only roller species in Europe and one of the continent's most colorful birds. Declining across much of its western range due to agricultural intensification and habitat loss.
Scarlet Macaw
The scarlet macaw is one of the most iconic tropical birds with its dazzling tricolor plumage. These highly intelligent parrots form lifelong pair bonds and can live over 75 years in captivity. They play an important ecological role as seed dispersers in Neotropical rainforests.
