Tree swallow

Tachycineta bicolor


The male has mostly glossy blue-green upperparts, with the wings and tail being blackish. The underparts and the cheek patch are white, although the underwing coverts are grey-brown.


Spotted in a tree in a wetland at Flaming Geyser State Park.


The tree swallow eats mostly insects, with some molluscs, spiders, and fruit. In North America, flies make up about 40% of the diet, with beetles and ants supplementing it. Otherwise, the diet is about 90% flies. The seed and berry food is mainly from the genus Myrica, which is mainly taken in the all four of the Northern Hemisphere seasons except summer.
