Yesterday mid-morning my urban neighborhood experienced a marvelous feeding frenzy. Over about a one block area, 5 chimney swifts, 1 tree swallow, 2 rough-winged swallows and about 25 dragonflies were all feeding about 12-15 above the ground in a very animated frenzy. The dragonflies were already there when the bird flock arrived. The swifts and swallows were not pursuing the dragonflies at all but I could see captures being made of some small pale insect. I couldn't find any on the ground or get details. The event lasted about 20 minutes then the birds disappeared and the dragonflies went back to their slow patrols over the neighborhood. I believe the dragonflies were mostly green darners as that is who is typically at my pond about 1/2 block from this event.
