Passerine refers to which group of birds?

• A. A seabird.
• B. A large waterbird.
• C. A member of the order Passeriformes, which includes perching birds and songbirds.
• D. A bird of prey.

Answer: (C)

Passerine refers to the order Passeriformes, the group known as perching birds or songbirds. This classification is about evolutionary relationships, not habitat or lifestyle, and perching feet (three toes forward, one back) are a common functional feature that reflects how many of them settle on branches. Many passerines are famous for their vocalizations, which is why they’re often called songbirds, though not all sing-richly. They include a vast diversity—from sparrows and finches to thrushes and crows—making them the largest bird group. The other descriptions describe birds by where they live or what they eat, not by their taxonomic grouping, so they don’t define this term.
