The Tree Swallow (Iridoprocne bicolor) is a 5 to 6-1/4 inch swallow found from Alaska, through Canada to California. It is steely blue-black or green-black above and solid white below. This bird is tireless in its endless circular glides in its pursuit of insects.

As the Tree Swallow flies, it constantly calls with a series of twittering notes.

You'll find the Tree Swallow in open country preferably near water, marshes, mountain meadows, along lakes and streams. The nest is a feather-lined cup in a hole in a tree, building or nest box. There are usually from 4 to 6 white eggs, sometimes as many as 10.

This bird generally eats insects but will also take bayberries in winter.
