Eurasian Tree Sparrow
A chestnut-capped sparrow whose unusual North American foothold began with nineteenth-century introductions around St. Louis.

Artwork inspired by Paul Cornoyer
Eurasian tree sparrows resemble male house sparrows but have a complete chestnut crown, a small black cheek spot, and a neater black bib. In North America they remain strongly associated with the St. Louis region and adjoining Mississippi and Missouri river corridors.
Look in small flocks around brushy edges, grain facilities, feeders, older neighborhoods, and agricultural settlements. The bird is introduced rather than native, but its limited continental history makes a St. Louis sighting biogeographically remarkable rather than merely another backyard sparrow.

Separate Eurasian Tree Sparrow from look-alikes
- Face
- Confirm a round black spot centered on each white cheek.
- Crown
- Unlike a male house sparrow, the chestnut color covers the entire crown.
- Flock
- Scan mixed sparrows at seed, grain, or weedy edges around the St. Louis region.
- Record
- Photograph sightings outside the familiar core because range changes are useful.
Good to know
Its North American population traces to birds released in St. Louis in 1870, making local geography part of the identification story.
