NORTHERN ROUGH-WINGED SWALLOW
The Northern Rough-winged Swallow is a fairly common breeder in the CW Region. Breeding habitat usually includes riverbanks and culverts near water. Trends suggest a yearly decrease but have a high range of error. This species is also not very well monitored by the BCN Survey. Photo: © Eric Secker |
