Anna’s Hummingbirds normally have a body temperature of around 107 degrees Fahrenheit—that’s a scorching temperature for a human. When outside temperatures fall, Anna’s and many other species of hummingbirds enter torpor. Their breathing and heart rate slow, and their body temperature can fall as low as 48 degrees Fahrenheit When the temperature warms, the hummingbirds can become active again in a few minutes.
In their thrilling courtship displays, males climb up to 130 feet into the air and then swoop to the ground with a curious burst of noise that they produce through their tail feathers.
Hummingbirds have tiny legs and can neither hop nor walk, though they can sort of scoot sideways while perched.
