By 7.45 most of them had left the orchard. I saw a Least Flycatcher alight on a brancli of an apple tree near me, and when it saw a cankervvorm move, it would fly and snap it up from the leaf, I saw it take nine in this way before it flew away. In the swamp a Yellow Warbler came to the wil- lows, and, after foraging in the top for a time, alighted on one of the shoots that was infested with the gipsy moth, took fifteen of the larviB in less than five minutes, then flew out of sight. A Nashville Warbler also came and remained among the willows for about half an hour, and took forty-two gipsy moth larvse while in sight, but must have taken away many more, for he was not in sight all the time.
