About the American tree sparrow
- The American tree sparrow is a plump songbird with a rusty cap, a bicolored bill, and an eyeline on a gray face.
- From fall to spring they eat mostly seeds. During summer they eat amlost exclusively insects like beetles, moths and caterpillars.
- They will nest on or near the ground at the base of a shrub or only as high as four feet in a spruce or willow tree.
- Parent birds incubate eggs for ten to fourteen days. Young are able to leave the nest in about two weeks.
- Fun fact: Despite having "tree" in their name, American tree sparrows are ground birds. They forage on the ground, nest on the ground, and breed in scrubby or partly open areas.
- American tree sparrows migrate. Expand the "Migration animation" section below to learn more.
