In British Columbia, purple martins (Progne subicolis) have increased from a few pairs nesting on southern Vancouver Island in the 1980s, to more than 140 pairs on Vancouver Island and the lower mainland in 1998. The increase is attributed to a volunteer-run nest box program initiated in the 1980s and carried on today. Threats to the species’ recovery include volunteer “burnout,” small numbers, and the decaying condition of pilings on which nest boxes are placed.
