The ruby-throated hummingbird is a migratory bird, spending the winters in Central America before traveling north to spend the summer in places like Michigan to breed. These birds are only about 3 inches long on average and weigh only 3.6 grams. While both the males and females of this species are a bright, emerald green color on their backs, the males also are covered with iridescent ruby red feathers on their throats.
The ruby-throated hummingbird is an important pollinator that feeds on over 30 species of plant and is especially attracted to red, tubular flowers. They pollinate columbine, beebalm, and many other native plant species by transferring grains of pollen from flower to flower on their wings and beaks.
