Trochilus colubris. Lake Umbagog, Maine. 1896. Attacks a Kingbird. Aug.16. As I was leaving the Upton landing at 1 P.M. I saw a Hummingbird chasing a Kingbird over the open marshes 50 or 60 feet above the ground. Keeping above the big clumsy fellow it gave him a good dose of the medicine which he is so fond of administering to the Crows and Hawks darting down at and apparently striking his head and forcing him to dodge as well as to put forth his best speed. At length the Hummer ceased this evidently wanton persecution and, rising and falling in long, deep undulations, shot off for the nearest woods looking no bigger than a Bumble Bee against the white sky.
