Swallow (I think) or Maybe Swift

Taking a picture of a flying bird, at dusk, and using the telephoto to try to bring it closer is a real challenge. I must have taken 3 dozen shots of different ones of the same flock and, as poor as it is, this is the best of the lot.
These birds are so quick and nimble in the air I can't see how they would ever miss a flying bug. And if they did they'd turn on a dime and get it on the rebound. They're small, about the size of a bat, but they occasionally set their wings and soar of a second or two. Bats can't do that.
