Eurystomus The Rollers are an Old World family of near passerine birds. They resemble crows in size and build, but are more closely related to the kingfishers and bee-eaters. They share the colourful appearance of those groups, blues and browns predominating. The two inner front toes are connected, but not the outer one. These are insect eaters, usually catching their prey in the air. They often perch prominently whilst hunting, like giant shrikes. The group gets its name from the aerial acrobatics some of these birds perform. These are birds of warm climates. They nest in an unlined tree-hole, and lay 2-4 eggs. The eleven species are: Genus Coracias Genus Eurystomus Reference - Kingfishers, Bee-eaters and Rollers by Fry, Fry and Harris, ISBN 0-7136-8028-8
