roller

roller,

common name for brightly colored Old World birds noted for performing somersaults in flight. They include the rollers proper (subfamily Coraciinae) and ground rollers (subfamily Brachypteraciinae; sometimes considered a separate family, Brachypteraciidae) of the family Coraciidae, as well as the monotypic cuckoo roller (Leptostomus discolor) of another family, Leptostomatidae.

The rollers comprise approximately a dozen species of solitary, jaylike birds, widespread throughout the tropical and temperate areas of the Old World. They are stout-bodied and large-headed birds, ranging from 9 1-2 to 13 in. (24–33 cm) long, with long, straight beaks that end in hooked tips. Their colors run to greens, blues, and reddish or yellowish browns, with little distinction between sexes. Rollers are strong flyers and feed while on the wing, usually on insects and small birds but occasionally on fruit. They lay their three to six white eggs in tree or rock holes, to which they add bits of grass, straw, or feathers. The slightly smaller tropical broad-billed rollers (genus Eurystomas) do not actually tumble or roll in flight.

The five species of ground rollers are confined to the island of Madagascar. They differ from the true rollers in being ground feeders and thus show the expected adaptations of this way of life: longer and stouter legs; shorter, more rounded wings; and less bright but more cryptic coloration. Four species inhabit the forest floor, and one, the 18-in.-long (46-cm) Uratelornis chimaera, dwells in arid scrub. Ground rollers feed on insects and small animals and build their hole nests in the ground.

The cuckoo roller is also found on Madagascar, as well as on the nearby islands of Comoros and Mayotte. It is about 17 in. (43 cm) in length and somewhat resembles the cuckoo in its coloration and its crested head. It differs from all other rollers in the possession of an outer toe capable of being turned backwards and a bill overhung with large tufts of feathers. A creature of forest and brushland, it feeds on large insects and lizards and lays its eggs in a tree-hole nest.

Rollers are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Roller

(Coracias garrulus), a bird of the order Coraciiformes measuring about 34 cm long and weighing about 190 g. The stiff plumage is greenish azure; the top of the wings and the back are brown. The roller occurs in Europe, Southwest Asia, and northwestern Africa. In the USSR it is present as far east as the Altai and as far north as Estonia and the Tatar ASSR. The bird winters in the tropical and southern regions of Africa. It nests in hollows and, in the south, in holes dug out of cliffs; less commonly it nests in buildings. A clutch contains four to six white eggs, which are incubated for 18 or 19 days. The roller feeds on large insects, lizards, frogs, and, sometimes, rodents. In the autumn its diet includes grapes and berries.
