Violet-green Swallow

Violet-green Swallow - Tachycineta thalassina 

The Violet-green Swallow is an aerial insectivore and according to Sibley, tends to feed more over land than other swallows, but you could have fooled me. The only time I have identified these swallows is over water. 

This Violet-green Swallow was on the roof next to our rental home on the lake in Nelson, BC.

Swallow species can be categorized by nesting behavior either as a cavity-nester or as a mud-nester. Violet-green Swallows, together with Tree and Northern Rough-winged Swallows, build their nests in holes and crevices of trees, cliffs, or banks. Barn, Cliff, and Cave Swallows build their nests from mud.
