Vireo philadelphicus. Lake Umbagog, Maine. 1894. Among many small birds in a mixed flock in the birch Sept. 3 grove on the Point I recognized a Philadelphia Vireo. The last was very tame and I watched him some time at close range. He appeared to feeding chiefly on caterpillars, --smooth, greenish or brown ones. I saw him take and swallow one which was fully two inches long. It gave him considerable trouble and he was obliged to shake it and beat it violently with his bill before he could get it down. Sept. 9. It was a little foggy at daylight this morning, a fact which may account for the finding, by Will Sargent, in the middle of the Lake, to-day, of a Philadelphia Vireo floating dead, back up. It doubtless became bewildered while attempting to cross the Lake and flew about in circles until exhausted.
