[cayugabirds-l] swallowing insects

[Eben McLane]

Watched hundreds of assorted swallows feeding for a couple of hours  
this afternoon over nearby fields and lawns here in Scipio Center.  
They paused occasionally to rest on overhead wires before resuming the  
feeding frenzy. Some tiny winged insects were swarming; I didn't get a  
good look at them, but I assume ants. Migrating flycatchers also  
showed a good deal of interest at the woods edge (pee wees, phoebes, 2  
Great Cresteds and 1 Olive-sided). After two hours all the swallows  
flew south en masse. Any idea what insects were causing such a frenzy?
