THE ROLLERS
(Family Coraciidce)
This is a small, exclusively Old World group of often brilliantly colored birds, showing points of affinity with the Motmots and Kingfishers, especially agreeing with the latter in the greater or less union of the toes.
They are of moderate size, few exceeding twelve or fourteen inches in length, and have ten primary quills and twelve tail-feathers, while structurally they are distinguished by having the oil-gland nude, the bridge (desmognathous) form of palate, and functional caeca, the latter sometimes two inches long. They are comprised in two well-marked subfamilies, — the Leptosomatince and the Cora-ciince, or true Rollers.
