Hummingbirds

Hummingbirds as you know are small birds that flap their wings very fast and can hover in place. They can move their wings 12 - 90 times per second depending on the species. They do this hovering while feeding on nectar in flowers as well as hummingbird feeders that people set up for them.
The smallest hummingbird is the bee humminbbird and it is only 2 inches long and weighs .06 ounce. Some hummingbirds can live more than 10 years but the more common North American species live about 3-5 years. Most North American hummingbirds nest as far north as southern Alaska but they spend their winter in Central America. Based on their body length they have the longest migration of any bird. Many make an 18-hour flight across the Gulf of Mexico with no place to land or feed.
