Types of Hummingbirds You'll Actually See in the US

Worldwide, there are 366 hummingbird species, overwhelmingly concentrated in Central and South America. That number is interesting but not especially useful if what you actually want to know is what's hovering at your feeder right now, because the realistic answer is much smaller: depending on where you live, you'll likely only ever regularly see somewhere between one and a handful of species in your own yard. This is a practical guide to those, not an exhaustive tour of every hummingbird on Earth.

How Many Species Actually Reach the US

According to the U.S. Fish and Wildlife Service, 15 hummingbird species regularly occur in the United States, with roughly 11 additional species showing up as rare vagrants, individuals blown off course or wandering north of their normal range. That's 26 species total ever realistically documented here, out of the 366 that exist across the Americas as a whole, a figure FWS itself presents as their current count rather than a permanently fixed number, since species boundaries do get revised over time as research continues. Only three US species are year-round residents rather than seasonal migrants, and Anna's Hummingbird, common along the West Coast, is one of them. Everywhere else, "how many types of hummingbirds will I see" really depends on which side of the country you're on and what time of year it is.

It's worth sitting with how lopsided that 366-to-15 ratio really is. The overwhelming majority of hummingbird diversity is a Central and South American story, not a North American one; places like Colombia and Ecuador host well over 100 species each in a single country, largely thanks to the sheer range of elevations and microclimates the Andes create. The US, by comparison, sits at the thin northern edge of hummingbird range generally, which is exactly why a US backyard's realistic species list is so much shorter than the global number suggests.

East of the Great Plains: Ruby-Throated Owns Summer, Not Necessarily Winter

Through spring and summer, the answer for most of the eastern half of the country really is simple: the Ruby-throated Hummingbird is the only species that regularly breeds there, and if you're seeing a hummingbird east of the Great Plains between April and September, it's almost certainly this one. Where the simple version breaks down is fall and winter, and this is the part most identification guides gloss over. Per eBird's own reporting, "from October to January, Rufous Hummingbird is the most common species by far in the East, outnumbering other species by up to ten to one." That's not a rare fluke sighting, it's become a well-documented, increasingly common pattern since the 1980s, with individual Rufous Hummingbirds now successfully wintering as far north as Massachusetts some years. Beyond Rufous specifically, eBird notes that Calliope, Black-chinned, and Allen's Hummingbirds now occur almost annually in the Northeast during the same fall-winter window, alongside rarer one-off visitors from further west. If you spot a hummingbird at an eastern feeder in November, the honest answer is that it's more likely a western species passing through or wintering over than a very late Ruby-throated.

West of the Rockies: A Regular Cast to Learn

West of the Rockies, more species overlap regularly, and it's worth learning a handful by name rather than treating "hummingbird" as one interchangeable bird. Anna's Hummingbird is the most likely to be a true year-round neighbor rather than a seasonal visitor. Black-chinned Hummingbirds are common across a wide swath of the West and Southwest. Rufous Hummingbirds pass through in large numbers on both legs of migration and are known for their combativeness, more on that below. Broad-tailed Hummingbirds are common in the central Rockies, often breeding at elevations above 10,000 feet. Calliope Hummingbirds, per Birds and Blooms, are "North America's smallest breeding bird and the smallest long-distance migrant," at about 3 inches long and roughly a tenth of an ounce, though notably not the smallest hummingbird species in the world; that title belongs to the Bee Hummingbird, found only in Cuba and never documented in the US. Costa's Hummingbirds round out the group as a desert specialist across the Sonoran region.

How to Actually Tell Them Apart

Four things do most of the work: gorget (throat patch) color, size, range, and season. Gorget color is the least reliable of the four on its own, since it's produced by structural iridescence rather than pigment, meaning the same throat patch can look brilliant red or nearly black depending on the angle of light, a mechanism covered in full in our hummingbird colors guide. Size is more consistent: a Calliope looks noticeably smaller than a Rufous or Anna's side by side. Range and season narrow things further than most people expect, since, as covered above, "what's normal here right now" changes a great deal between spring and winter in many parts of the country. Behavior can help too. Per Cornell's All About Birds, Rufous Hummingbirds are "one of the feistiest hummingbirds in North America," and during migration stopovers "may chase off resident Broad-tailed, Broad-billed, Violet-crowned, and Black-chinned hummingbirds" from a feeder, with "all ages and both sexes" showing this aggressive streak. A hummingbird that's aggressively monopolizing a feeder and chasing off every other species, not just other individuals of its own kind, is a reasonable clue you're looking at a Rufous.

Why Migration Season Muddies the Picture

Range maps make it look like species swap over cleanly on a fixed date, but the real picture, covered in more depth in our hummingbird migration guide, is messier and more interesting. Migration happens over weeks, not a single day, and different species pass through the same regions on overlapping but not identical schedules. That overlap window is exactly when a backyard birder is most likely to see something unexpected, a second or third species briefly sharing space with whichever bird is the usual local resident. If a feeder that's hosted only Ruby-throated Hummingbirds all summer suddenly attracts a visibly different-looking bird in late August or September, migration timing, not a sudden change in what lives nearby, is almost always the explanation.

Species vs. Sex: Two Different Questions

It's worth being clear about what this post does and doesn't answer. Figuring out which species you're looking at is a different question from figuring out whether a bird of a known species is male or female, which usually comes down to the presence, size, or color of the gorget and some tail-shape differences within that one species. Our male vs. female hummingbird guide covers that second question in depth; this post is about the first one, identifying the species itself before worrying about which sex you're looking at.

The Vagrants and Rarities

Beyond the 15 regularly-occurring species, roughly 11 more have been documented in the US as genuine rarities, individuals well outside their normal range, usually from Mexico or Central America. These sightings tend to draw serious birders from long distances but aren't something a casual feeder-watcher needs to worry about identifying. If a hummingbird at your feeder doesn't match any of the common species for your region and season, the far more likely explanation is a lighting or angle issue with a common species than a genuine rarity.

It's worth keeping a sense of proportion here. A genuine vagrant sighting is exciting precisely because it's rare enough to be reported and verified by other birders, often with photographs submitted to a regional rare-bird alert. For everyday identification purposes, working through the common, regionally-expected species first, and only reaching for a rarity as a last resort once size, season, and range have all been ruled out, will get you the right answer far more often than assuming every unfamiliar-looking bird is something exotic.
