Passerine

참새목

Definition

A member of the order Passeriformes, the largest order of birds, commonly known as perching birds or songbirds.

Detailed Explanation

Passerines account for roughly 6,500 of the world's 10,000+ bird species and dominate terrestrial avifaunas on every continent except Antarctica. Their hallmark adaptation — an anisodactyl foot with three toes forward and one back — enables a firm grip on branches. Passerine vocal learning is one of the few parallels to human language acquisition, making songbirds important neurobiological models for studying speech and vocal learning.
