Altricial chicks of an unknown species of passerine.

Quail chick 02

California Quail - a precocial chick.

A bird that just hatched out of its egg [1].

A hatchling can either be precocial (covered in down, able to feed themselves and be able to move), altricial (naked, blind and helpless) or a mix of both (terns and gulls - are born with down, can move but rarely leave the nest)[2].
