293. Tree Swallow

Despite the fact that Tree Swallows  (Tachycineta bicolor) are not uncommon on southern Vancouver Island we only have a single record of this species at Leaning Oaks, a pair of birds on migration in April.  It is very likely we have overlooked "fly over" Tree Swallows.   Like the much commoner Violet-green Swallow, Tree Swallows are cavity nesters, using woodpecker holes,  rotted cavities in trees and nest boxed to raise their families.  Here on southern Vancouver Island they are more closely associated with water than Violet-green Swallows, which uses a wider variety of habitats.
