Roller

[roh-ler]

The rollers are an Old World family of near passerine birds, related to the kingfishers and bee-eaters. The group gets its name from the aerial acrobatics some of these birds perform during courtship or territorial flights.

Description

Rollers resemble crows in size and build, ranging from 25 to 27 centimetres in length. They share the colourful appearance of those groups, blues and browns predominating. The two inner front toes are connected, but not the outer one.

They are insect eaters, with Eurystomus species taking their prey on the wing, and those of the genus Coracias catching it on the ground. They often perch prominently whilst hunting, like giant shrikes.

These are birds of warm climates. They nest in an unlined tree-hole, and lay 2-4 eggs. The eggs hatch after 17-20 days, and the young remain in the nest for approximately another 30 days.

Species

The eleven species are:

FAMILY: CORACIIDAE
