BANK SWALLOW

The Bank Swallow is an uncommon breeder in the CW Region. Bank Swallows usually nest in banks or cliffs - frequently near water. These areas are poorly sampled by the BCN Survey. Conclusions regarding this species population trend cannot be drawn from the limited amount of data that has been collected. Photo: © Eric Secker
