Trochilus oolubris 
Lake Umbagog, Maine. Attacks a Kingbird. 
1896. As I was leaving the Upton landing at 1 P.M. I saw a 
Aug.16. Hummingbird chasing a Kingbird over the open marshes 50 or 60 
feet above the ground. Keeping above the big clumsy follow 
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.
