Why it matters
The American Tree Sparrow, or *Spizelloides arborea*, is a hardy visitor that travels from the Arctic tundra to winter in more temperate regions. Its rounded wings and notched tail are functional adaptations for navigating the dense brush and open fields where these birds forage for seeds during the colder months.
