The American Tree Sparrow is a small, active sparrow known for its distinctive rusty cap and bicolored bill. It is a common winter visitor to open habitats across much of North America.
Where to spot
Breeds in the Arctic tundra and boreal forests of Alaska and Canada. Winters across most of the contiguous United States, particularly the northern and central parts, and southern Canada. Prefers open fields, shrubby areas, weedy margins, and gardens.
How to spot
Look for its rusty crown, a distinctive bicolored bill (dark upper mandible, yellow lower mandible), and a small, dark spot on its plain chest. They often feed on the ground, kicking with both feet to uncover seeds.
When to spot
Primarily a winter visitor to most of its observable range, arriving in late autumn and departing in early spring. During winter, it is active throughout the day, foraging in flocks.

Despite its name, the 'Tree' in American Tree Sparrow refers to its preference for perching in small trees and shrubs, rather than nesting in trees, as it actually nests on the ground.
