dellrose.........they do a lot of high pitched chittering.........yesterday when I was trying to get some in flight pics I noticed that directly above me and at a very high altitude there was a large flock of swallows (about twice the size of what shows in the pic). They stayed there for quite awhile. There must have been a large number of flying insects caught in a thermal and they were feeding on them, At least that's my theory.
