Although some Bank Swallows arrive in April, most do not arrive until mid May. Most have departed Manitoba by late August. Large flocks of this species and other swallows in the late breeding season (August) should not be atlassed as these are clearly migrants.
Colonies distinctive enough to document even when abandoned. Typically, dozens of nest holes are present, although not all will be active. It is therefore usually possible to obtain confirmed breeding of this species.
Bank Swallow nest in colonies on high river banks, lake banks, road cuts, gravel pits, quarries and other sandy substrates. They will forage above wetlands and elsewhere where large insect emergences occur.
