"Swallows usually show up in the spring time or when winter months are over in Alaska."
Tree SwallowCommon and widespread throughout most of North America, breeding as far north as Alaska and wintering to Panama. A medium-sized swallow, with gleaming white underparts. Adult males are bright iridescent blue-green above; females and immatures are duller brownish with limited or no iridescence. Always note compact shape, fairly broad wings, and slightly notched tail. Occurs in a variety of open habitats including grassy fields, lakes, and marshes. Often in flocks, sometimes mixed with other species of swallows. Breeds in cavities, including human-made nest boxes. Listen for cheery gurgling calls. Compare especially with Violet-green Swallow; note Tree Swallow does not show extensive white wrapping around the cheek or the sides of the rump. |
