Found across most of non-arctic Canada, tree swallows in migration can be an impressive sight, flocking in the thousands and flying with great agility. Tree swallows tend to nest near bodies of water, and are particularly partial to dead trees, although they can also be found nesting in eaves, nest boxes, and on fence posts. The Head and shoulders of the male tree swallow change from an iridescent blue in spring to green in autumn.
