Hummingbirds can be found in North America, Central America, South America and many islands of the Caribbean Sea. Almost half the species live in the "equatorial belt" between 10 degrees north and south of the equator.
According to the International Ornithologists' Union (IOU), the hummingbird family has 366 species and 112 genera, mostly south of the United States. Hummingbirds comprise the family Trochilidae, among the smallest of birds, with most species measuring in the 3"-5" range. Tens of millions of these tiny birds inhabit the United States and Canada at least part of each year, bringing joy to so many nature lovers!
Fewer than two dozen species venture into the United States and Canada, and only a few species remain year-round in North America. Listed below are estimated hummingbird populations for several species as calculated by the American Bird Conservancy, using data from Partners in Flight (PIF) population & conservation data along with data from the Cornell Lab of Ornithology.The numbers do not reflect world-wide hummingbird populations.
