_ more than half the world's bird species. The precise meaning of the word passerine is "sparrowlike," and a common, though possibly misleading, alternative is "perching birds" (many non-passerines perch).

Legs vary according to life-style, for instance, whether the bird forages on the ground or perches in foliage. Bill shapes vary with the food eaten - most commonly insects, fruit, or seeds. The shape of body, wings, and tail help too, and song can often be decisive in identifying a passerine species.
