The birds of this order, except the Cuckoo-roller, have the front three toes joined at the base. Their feet are noticeably small and their leg muscles are similar. Plumage development and arrangement follow a common pattern and most members are very colorful. The bills of these birds vary greatly. Some have long, curved bills while others are huge in proportion with a peculiar shape, and often have an elaborate casque. Their diet consists mostly of meat, fish and insects, though some will also eat fruit and berries. The length of these birds varies from 3 ½ inches (Todies) to 5 feet (Hornbills). Nests are made in holes, and eggs are white in color. The young are altricial, except for the Hoopoes.
