Blue-bellied RollerThe Blue-bellied Roller, Coracias cyanogaster, is a member of the roller family of birds which breeds across Africa in a narrow belt from Senegal to northeast Democratic Republic of the Congo (formerly Zaire). It is resident, apart from some local seasonal movements, in mature moist savannah dominated by Isoberlinia trees. This is a common bird of warm open country with some trees.

Widespread and common throughout its large range, the Blue-bellied Roller is evaluated as Least Concern on the IUCN Red List of Threatened Species.


Description

The Blue-bellied Roller is a large bird, nearly the size of a Jackdaw at 28-30 cm. It has a dark green back, white head, neck and breast, with the rest of the plumage mainly blue. Adults have 6cm tail streamers.

Males and females look alike, but the juvenile is a drabber version of the adult.

Blue-bellied Roller is striking in its strong direct flight, with the brilliant blues of the wings contrasting with the dark back and white head, and the tail streamers trailing behind.

The display of this bird is a lapwing-like display, with the twists and turns that give this species its English name.
