Infradiviso: Passerae

Passerae is a infradivision of birds that includes higher land birds, birds of prey, near-passerines and perching birds. This infradivision has more species of birds than the others, including the passerines, having more than half the world's birds.[1]

The name "Passerae" is derived from Passer domesticus, the scientific name of the eponymous species (the House Sparrow) and ultimately from the Latin term passer for Passer sparrows and similar small birds.

Anatomy

Many of the members have anisodactyl ("perching") feet and zygodactyl feet.[2] Trogons have heterodactyl, found in no other birds[3] while Bucerotiformes and Coraciiformes have syndactyl toes.[2] Mousebirds have pamprodactyl feet, also found in swifts - the outer toe is reversible.[2]

In Accipitriformes, Falconiformes and Psittaciformes, the bill is sharply hooked.[3]

Woodpeckers have sharp bills and very long tongues that are used to extract insects from underneath the bark; while their relatives, the barbets, have bills that are stout with a fringe of bristles at the base, are used to eat fruit.[3]

The bills of Passeriformes varies, from large and broad, as in broadbills[3]; decurved, as in some asities[3]; short, as in manakins; large and powerful, such as nuthatches[3]; long and thin, as in treecreepers; thick, as in estrildid finches[3], and so on.

Even the Fringillidae's bills are varied, the Hawfinch has a strong beak and cheek muscles that are capable of splitting hard tree seeds; the European Goldfinch has as cone-shaped bill which is ideal for eating most small seeds and the crossbills have bills adapted to split open spruce and pine cones.[3]
