Description

Allen’s gallinule, formerly known as the lesser gallinule, is a small waterbird with a compact head, short tail, and a short bill. While it may appear dark from a distance or in poor light, its plumage has green upperparts, violet underparts, and a white undertail. The head is black, and both the bill and legs are bright red. During the breeding season, males display a turquoise blue frontal shield, which is green in females. Apart from that, the sexes are similar, but the female is slightly smaller.

Although it is a weak flier, Allen’s gallinule holds the distinction of being the only species on the British and Irish bird list to have originated from the African tropics.
