While Anna's feeds, he chips this characteristic call during his meal.

This male Anna's Hummingbird (Calypte anna) "sings" while perched in a Juniper in Sedona, Arizona. This is a song which is very difficult to record and edit, since it is very low volume and tends to get lost in whatever background noise there is. The vocalization is highly modulated and sounds quite like distant human speech, quite unlike any other hummer I've heard. One must be right under the bird to catch his squeaky, scratchy, croaky sound.

The wingbeat of the Anna's is slower than most, which is logical, since they're one of the largest hummers normally north of Mexico. This one measures only 45 BPS!
