Hummingbirds are found only in the Western Hemisphere, with almost half the species living in the "equatorial belt" between 10 degrees north and south of the equator. While many species are found in Central America and South America, few make their homes in North America, either year-round or during migration season in the warmer months.
The hummingbird family is very large, with 366 species and 112 genera. Hummingbirds comprise the family Trochilidae, among the smallest of birds, with most species measuring in the 3"-5" range.
Many hummingbirds spend the winter in Central America or Mexico, and migrate north to their breeding grounds in the southern United States as early as February, and to areas further north, even into Canada, later in the spring. The first arrivals in spring are usually males.
Fewer than two dozen species venture into the United States and Canada, and only a few species remain year-round.
Large numbers and species of hummingbirds exist outside of North America. Read more about:
