Find This Bird
One easy way to find Cliff Swallows is to look for their gourd-shaped mud nests clustered under horizontal overhangs—many a highway overpass is swarming with Cliff Swallows in summer. To find these birds while they’re out foraging, head to a lake, river, or wetland and seek out foraging flocks of swallows. Scan the swallows carefully, focusing on finding a square-tailed bird with a pale, pumpkin-colored rump and dark upperparts. Scan the upper levels of a foraging flock, as Cliff Swallows often forage higher than other species.
