Tree Swallow

Description:

The bill is tiny. The adult Tree Swallow has iridescent blue-green upperparts, white underparts, and a very slightly forked tail. The female usually has duller colours than the male, often more greenish than the more bluish male. (wikipedia)

Habitat:

Found in marshes and open fields. Tree Swallows nest in natural or artificial cavities near water and are often found in large flocks. They readily use nest boxes, including those built for bluebirds. The nest consists of multiple layers of grasses and thin twigs, and is lined with large feathers from other species. (wikipedia)

Notes:

Mostly eat insects, supplemented with fruit. Excellent fliers. Was in a nesting box with nest (also pictured) **Caught by BRI wildlife research biologists, as part of migratory bird banding and study. **
