The American Tree Sparrow is a small bird commonly found in North America, particularly in the northern regions during winter. It has a distinctive appearance, featuring a rusty cap, a grayish-brown body, and a prominent black spot on its chest. These birds prefer open habitats like fields and shrubby areas, where they forage for seeds and insects. Typically, the American Tree Sparrow migrates south from its breeding grounds in Canada and Alaska to the United States during the colder months. They are often seen in flocks, foraging on the ground or in low shrubs, and are known for their cheerful, melodic songs.
