Ruby-Throated Hummingbird
This variety is the most commonly seen one in the Midwest. It is easily attracted to backyard feeders. The male, with its emerald green back, is quite territorial and will aggressively defend its food supply. This makes for some entertaining hummingbird battles. They are 3.5" long, weigh 1/8 ounce, and beat their wings from 40 to 80 times per second. |
