Anna’s Hummingbird Facts

Anna's Hummingbirds are stunning forest birds of the far American West. They are well known for their mating display, in which males soar more than a hundred feat into the air then dive down making a screech with it's tail feather a few feet away from it's desired mate. Their normal body temperature is a sweltering 107 degrees Fahrenheit. When the temperature falls outside, Anna's Hummingbirds enter torpor, meaning their breathing and heart rate slows and their body temperature can fall by as much as 50 percent. They are also extremely protective of their feeding territory and will ferociously defend it. Native American legends say hummingbirds do several things, including poke holes in the sky making stars.
