The White-necked Jacobin is a small bright bird from the hummingbird family. It lives in the tropical forests of Central and South America and can hover in the air thanks to very fast wing beats.
The White-necked Jacobin differs from other hummingbirds by the bright white neck of the males and its large size for a hummingbird. It is important for nature as a pollinator of many tropical plants.
Hovers in the air in front of a flower and extracts nectar with a long tongue.
