Four species breed in Idaho and a fifth winters here — a richer lineup than anywhere in the eastern United States, where a single species does all the work. Three more have turned up as genuine rarities over the years, bringing Idaho's full recorded list to eight, though those three are single-digit records, not birds to expect at a feeder. Which of the real regulars you get depends less on where you are north to south than on how high you are. This guide breaks down which hummingbird you're actually looking at, whether that's a summer breeder tied to a specific elevation band or the winter specialist that's still expanding its Idaho range in real time.

Species grouped by frequency of sightings, statewide eBird data. Three additional species — Costa's, Broad-billed, and Ruby-throated — have been documented in Idaho as one-off or single-digit rarities too infrequent to chart reliably.

The Hummingbirds You're Most Likely to See

All four of Idaho's breeders are elevation specialists first and foremost — which one shows up at your feeder has more to do with how high you live than what month it is.

Black-chinned Hummingbird

Idaho's most common hummingbird at lower elevations, and the one most Treasure Valley gardeners are watching. Idaho Fish and Game calls it the state's most common hummingbird in the valleys, and the data agrees — it's reported on nearly a quarter of Idaho checklists at its August peak, more than any other species.

Quick ID: Adult males have a velvety black throat edged with a thin band of violet-purple that only shows at the right angle. Females and young are green-backed with plain pale throats — and are genuinely difficult to separate from female Calliope or Rufous in the field. Habit helps: Black-chinned pump and fan their tails almost constantly while hovering.

Rufous Hummingbird

The famous one, and the reason Idaho's hummingbird year has two distinct waves. Rufous breed here, but far more of them simply pass through — and they don't take the same road twice. They travel north up the Pacific Coast in spring, then return south through the Rocky Mountains in late summer. Idaho sits squarely on that southbound mountain route, which is why August reports are more than double what they are in May.

They're also famously pugnacious. A single male will attempt to run every other hummingbird off a feeder, regardless of size.

Quick ID: Adult males are unmistakable coppery orange. Females and young are green-backed with rufous-washed flanks, rufous at the base of the tail, and a few red flecks at the throat. Note that female Rufous cannot be reliably separated from Allen's in the field — but Allen's has no accepted Idaho records, so in Idaho a rufous-flanked female is a Rufous.

Calliope Hummingbird

The smallest bird in North America — just over three inches long, weighing about as much as a ping-pong ball — and a genuine mountain specialist. Calliope are strongest in Idaho's northern and central mountains, in open forest, mountain meadows, and willow thickets. They're also the earliest of the four to arrive.

Small doesn't mean short-lived: the oldest Calliope Hummingbird on record, a female of at least eight years, was banded and later recaptured right here in Idaho.

Quick ID: Tiny even by hummingbird standards, with a short tail that doesn't reach past the wingtips at rest. Males show magenta streaks radiating down a white throat rather than a solid gorget — unlike anything else in Idaho. Females are best left to a bander.

Broad-tailed Hummingbird

The high-country species, and Idaho sits at the northern edge of its breeding range. Broad-tailed nest at elevations up to around 10,500 feet, and their Idaho distribution is sharply drawn: they are the most-reported hummingbird in eastern Idaho, present in the central mountains, and effectively absent from both the Treasure Valley and the Panhandle. If you're near Idaho Falls, Pocatello or Teton Valley, this is your bird — and if you're in Boise, you're unlikely to see one at all.

Quick ID: Males have a rose-magenta throat and, more usefully, produce a distinctive metallic trilling whistle with their wings in flight — you'll often hear a Broad-tailed before you see one. Females are green above with buffy, cinnamon-washed flanks.

Telling the Confusable Females Apart

Female Black-chinned, Calliope, and Rufous all show up in Idaho's lower valleys, and none of the three has a distinctive gorget to fall back on. This is the identification problem the guide doesn't have room for, so it's worth working through properly.

Start with rufous coloring. Any wash of rufous or copper on the flanks, or rufous patches in the tail, points straight to Rufous — Cornell's own species-comparison notes are explicit that Black-chinned and Calliope both lack this entirely, showing dull grayish-white or peachy underparts instead. If you see orange anywhere on the bird, it's not Black-chinned or Calliope.

No rufous? Then it's size and tail. Calliope is genuinely the smallest of the three, with a short tail and short wings that end up roughly level when the bird is perched — unlike every other species on this page, where the wingtips fall noticeably short of the tail tip. Black-chinned is larger, with a longer bill, and its wingtips reach the tip of the tail or just beyond it. Behavior helps too: Black-chinned pump and fan their tails almost constantly while hovering, a habit Calliope doesn't share as consistently.

In short: orange wash anywhere = Rufous. No orange, notably tiny with a stubby tail = Calliope. No orange, larger, tail-pumping = Black-chinned.

Hummingbirds in Idaho in Winter

None of the four breeders above stick around for winter. One entirely different species does — and its Idaho story is still being written.

Anna's Hummingbird — Idaho's Winter Bird

The most remarkable hummingbird story in Idaho, and one that's still unfolding. Anna's is a Pacific Coast species that has been expanding its winter range inland and northward for decades, helped along by urban landscaping and backyard feeders.

Idaho's first record was in 1976. It stayed rare through the 1990s, picked up in the early 2000s, and has climbed sharply over the past decade — overwhelmingly around Ada County, with smaller numbers in the Panhandle and the mountain valleys. Eastern Idaho is the exception: around Idaho Falls, wintering Anna's are still essentially unrecorded. The Intermountain Bird Observatory at Boise State now bands roughly two hundred each winter, from Boise to New Meadows to Hailey.

And they're staying. Researchers have documented individual birds returning to the same yard in successive winters, and in 2020 they confirmed Idaho's first successful Anna's nest — in a southeast Boise garden, on a Rose of Sharon. Their published conclusion is that Anna's "may now be a sparse year-round resident in parts of Idaho." Our Idaho hummingbird calendar tracks the winter season month by month.

Quick ID: Males have an iridescent rose-pink crown and throat — the only North American hummingbird with the pink extending over the head. Females are grey-green with a few red flecks at the throat, chunkier and less pointed than the other four. In Idaho the calendar settles it: any hummingbird between November and March is an Anna's.

If You're Lucky: Idaho's Rare Visitors

Beyond the five regulars, Idaho's official state list includes a small number of genuine vagrants — extreme rarities, not birds to expect at a feeder.

Costa's Hummingbird

One bird banded at Meridian in 2004 stayed until January — Idaho's only confirmed record of this desert Southwest species. Adult males are unmistakable if one ever turns up again: a deep violet-purple crown and throat that extends into elongated points down the sides of the neck, a pattern no other Idaho species shares. Females are plain green above and whitish below, closer in look to a female Black-chinned than to anything with color.

Broad-billed Hummingbird

One bird banded at Caldwell in 2004 — the only other genuine desert Southwest specialty on Idaho's list. This one needs no tail-feather forensics: a bright red bill tipped in black, paired with a shimmering blue throat and rich green body, has nothing else on Idaho's list to be confused with. Females are duller, golden-green above and gray below, but keep the same telltale red-and-black bill.

Ruby-throated Hummingbird

About four records exist of this eastern species reaching Idaho — a genuine surprise this far from its normal range east of the Rockies. Adult males show a brilliant iridescent ruby-red gorget, easily confused with Idaho's other red-throated species (Anna's, Broad-tailed) at a glance, but Ruby-throated's gorget stays confined to the throat rather than spreading up over the crown like Anna's, and it lacks Broad-tailed's audible wing trill in flight.

Frequently Asked Questions

How many species of hummingbirds are in Idaho?

Four species breed in Idaho — Black-chinned, Rufous, Calliope, and Broad-tailed — and a fifth, Anna's, is an expanding winter resident. Beyond those five, the state list includes rare vagrants: Costa's, Broad-billed, and Ruby-throated.

Are there hummingbirds in Idaho in winter?

Yes — Anna's Hummingbird has been wintering in Idaho in growing numbers since the 1970s, concentrated around Ada County, with Idaho's first confirmed successful nest recorded in 2020. Between November and March, any hummingbird seen in Idaho is almost certainly an Anna's.

What determines which hummingbird I'll see in Idaho?

Elevation, more than latitude. Black-chinned dominates lower valleys like the Treasure Valley, Broad-tailed holds the high country of eastern Idaho, and Calliope favors northern and central mountain meadows — the four breeders sort out largely by how high you live, not how far north or south.

How do I tell female Black-chinned, Calliope, and Rufous apart?

Check for rufous or copper coloring first — any orange wash on the flanks or in the tail means Rufous, since Black-chinned and Calliope both lack it entirely. If there's no orange, size settles it: Calliope is Idaho's smallest hummingbird with a short tail and wingtips that reach about level with the tail when perched, while Black-chinned is larger with wingtips falling short of the tail and a habit of pumping and fanning its tail almost constantly while hovering.

Why We Created This

Pop's Birding has been helping hummingbird lovers for three generations — and Idaho is home, so this one matters to us more than most. One of the questions our customers ask most often is "What hummingbirds are actually in Idaho?" — we built this guide to give a direct, sourced answer, not a generic one. Most hummingbird content treats a state as one uniform zone, but Idaho genuinely isn't one: which bird shows up at your feeder has far more to do with your elevation than your latitude, and a Boise backyard and a Sawtooth mountain meadow can have almost entirely different hummingbirds despite sitting in the same state. On top of that, Idaho has a real, still-unfolding natural history story most guides don't know exists — Anna's Hummingbird establishing itself as a wintering species here in real time, something that simply wasn't true a generation ago. We wanted a guide that actually captures both of those things, not a rewrite of a generic "hummingbirds in your state" template with Idaho's name swapped in.

How We Created This

Every number on this page comes from eBird checklist data (Cornell Lab of Ornithology), pulled statewide and from four representative Idaho counties — Ada (Boise), Blaine (Sun Valley), Bonneville (Idaho Falls), and Kootenai (Coeur d'Alene) — chosen specifically to cover Idaho's real elevation and geographic range: lower-valley Treasure Valley, central mountain resort country, high-elevation eastern Idaho, and the Panhandle.

We don't take every reported sighting at face value. Before any species went into a percentage claim, we checked its statewide peak against the same noise-floor standard used across this whole project: Ruby-throated sits at just 0.03% of checklists at its Idaho peak — a real, documented species, but statistically indistinguishable from a handful of individually twitched birds, not a population pattern. Costa's and Broad-billed don't even clear a statewide reporting threshold at all — both are single confirmed Idaho records, banded at specific sites in 2004, and we say so explicitly rather than either omitting them or implying they're more regular than two birds, twenty years ago, actually support.

The species grid above shows all eight species documented in Idaho, tiered by how common each one actually is rather than filtered down to only the statistically strongest — four real breeders in "Most Common," Anna's standing alone in its own "Winter Specialty" category, and the three genuine vagrants grouped as "Rare Visitors." That tiering comes directly from each species' actual peak frequency data, or for the three rarities, their genuinely single-digit record count — not an assumption carried over from any other state's guide. Idaho's own numbers, not Texas's or any other state's, decided that shape.

The elevation-based sorting described throughout this guide, and the framing of Anna's as a still-developing range expansion rather than a settled fact, are original analysis built from Idaho's own data and Idaho Fish and Game's and the Intermountain Bird Observatory's published findings — not a rewrite of a generic multi-state hummingbird overview.
