Word of the Week: Passerine

Today’s word is:

passerine

PronouncedPASS-er-in

Sciency Definition: A member of the order Passeriformes, the largest group of the class Aves.

Or I could have saidPerching bird.

What’s it do?  Members of the order Passeriformes are the perching birds, which include more than half of the living species of birds. They each possess feet adapted for perching or clinging. “Song birds” are all passerines but not all passerines are song birds; song birds just have the best use of the muscles used for creating vocalizations (the syrinx). Some song birds, instead of singing, create an incredible range of sounds including clicks, croaks, and mimics of sounds they hear in their environments.

Example sentence: Despite being categorized as passerines, crows and ravens do not use their syrinx muscles to produce songs.

Baby scrub jays might be passerines, but they have a song only a mother could love!
