Or so it seems. Driving last week, it seemed to be raining bugs. I won't describe what it's like walking in the grass. Of course, natural selection has provided enemies of insects. Among these, perhaps the most effective are the swallows.
Swallows are superior flyers, and they take virtually all of their food on the wing.
Of these, the barn swallow is the most familiar. Barn swallows are the best known of swallows in the Red River Valley. They occur in virtually every farmyard, and they occasionally nest on city buildings, as well. It may well be that cliff swallows are actually more numerous, however. It's not unusual to find several thousand nests of cliff swallows on a good-sized bridge.
