Broad-Tailed Hummingbird (Selaphorus platycercus) - Estes Park - Colorado
The shrill sound created by the wings of this broad-tailed hummingbird is silenced for a few moments as he perches in a tree. This tiny bird was keeping a sharp eye out for other males, running them out of his area whenever one got close. These birds take off and fly so fast that it's extremely hard to keep track of them. Luckily for me, this particular bird would return to this same branch after almost every flight, allowing me a few minutes to photograph him.
