Tree Swallow, male (Iridoprocene bicolor)

This is the male of the newer pair of Tree Swallows, the pair who claimed the second nest box we put up this spring. Box #1 was originally claimed by a pair of Tree Swallows, but hijacked by Bluebirds nine days later. So the Bluebirds are still using Box #1 and the newer pair of Tree Swallows, Box #2.
