Some interesting facts is a lt of times they are mistaken for insects and they can be the size of a penny! They can beat their wings up to 80 times a second and have an extremely fast heart rate. There are a total of 330 total species of hummingbirds and they live in a lot of different envirements, sometimes harsh. Some hummingbirds have even lived to be seventeen years old. There bones are hollow and light, just like most birds, and they are said to almost never fossilize. Recently, there was a 30 million year old fossil found, which shows how old these birds really are. prompt: Explain how hummingbirds are able to move their wings at a rate of 800 beats per minute,and what are they mistaken for?
