Most bird predators rely on surprise to take their prey. They are less maneuverable and so can’t catch a bird that is aware of them. So birds that see a predator will gang up on it and harass it until it becomes so peeved it leaves the area. Small birds harass crows, which rob nests of eggs and nestlings, and crows often mob and chase owls and hawks.
But hummingbirds do it mainly because they’re mean little bastards.
Whether you go after your prey with wings, wheels, or lips, a hummer can’t be beat.

That’s because nobody has ever survived to tell the tale.

Ten-yard penalty for unnecessary roughing.
Truth must be different on this side of the world. I get a picture of Elle MacPherson, Kathy Ireland and Rachel Hunter.
Are you callin’ Ponder Stibbons twee?
Oh, it was necessary, alright. 
That twee bastard’s got it coming to him.
Hummingbirds? Damn! So, Colibri, does the hummingbird violate all known laws of physics and thus prove the existence of god?
