Hummingbirds have heart rates 10 times as fast as a small child. Hummingbirds have the most rapid wing beat of all birds and are among the fastest fliers of small birds.

Hummingbirds have a unique flight mechanism, capable of prolonged hovering like a helicopter and they can fly backward rapidly. Bats have lived in America since the age of the dinosaurs. A mother bat who is nursing her young does not have time to eat many insects at night. Long-nosed bats help the desert plants by eating insects that infect those plants and make them sick. Pallid bats are of no benefit to farmers and ranchers and would not be missed if they disappeared.
