Violet-green Swallow

I found it hard to get a decent Violet-green Swallow photograph. These photos finally show their greenish crowns and violet backs. Field marks for separating them from Tree Swallows include the white lines around the backs of their eyes. Violet-green Swallows also show much more white on the sides of their rumps. This Violet-green Swallow posed for me at Seabrook, Washington, on 13 April 2021. This species breeds across western North America, from Alaska to central Mexico (and winters into Central America. They breed in dead snags, often in abandoned woodpecker cavities. They are much less likely than Tree Swallows to next in bird boxes.
