Tree Swallow

Tachycineta bicolor


This swallow averages 13.5 cm (5 inches) long and weighs about 20 g. 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. The juvenile plumage is dull grey-brown above and may have hint of a gray breast band.


Tree Swallows nest in natural or artificial cavities near water and are often found in large flocks.

Are you sure these are Tree Swallows? I see a buff or white patch above the upper mandible of the one taking flight and their chins look ruffs in color, which would make them Cliff Swallows.
