Iowa's documented hummingbird list is short — five species, fewer than every one of its six neighboring states (Missouri's ten, Illinois's seven, and Minnesota, Nebraska, South Dakota, and Wisconsin all at eight). Only one, Ruby-throated Hummingbird, breeds here or shows up in real numbers. Rufous Hummingbird is a genuine, if easy-to-miss, fall regular. The other three are true rarities, each with exactly two accepted state records.

This page's job is identification and confidence — which hummingbirds you're actually looking at in Iowa, and how sure you can be about it.

All 5 documented Iowa hummingbird species, grouped by tier — statewide eBird data, 2016–2025, cross-checked against the Iowa Records Committee's own accepted-record history.

The Hummingbird You're Most Likely to See

Ruby-throated Hummingbird

Iowa's only breeding hummingbird, and it dominates the state's hummingbird activity almost completely — its statewide eBird frequency peaks near 32%, well over a hundred times higher than any other species. Iowa DNR puts it plainly: "In Iowa, we mainly see only the ruby-throated hummingbird." Present late April through fall migration, with nesting concentrated May through August.

Quick ID: Males flash a brilliant ruby-red throat in good light, but it reads as solid black most of the time — the forked black tail is the more reliable everyday mark. Females have a plain whitish throat and a more rounded, white-tipped tail.

Iowa's Regular Fall Visitor

Once Ruby-throated numbers taper off in late summer, Iowa gets one more genuine, if easy to overlook, species passing through.

Rufous Hummingbird

Genuinely more regular than its rare-visitor reputation suggests. The Iowa Records Committee (IRC) classifies Rufous as Casual — not Accidental like the state's true rarities — and formally removed it from the official Review List in 2024. The committee's own language: it "undoubtedly occurs in Iowa every fall and is chronically under-reported." That's a real, recurring seasonal pattern, not a one-off.

Quick ID: Males glow with a fiery orange-red throat and a coppery-orange body — one of the most recognizable hummingbirds in North America. Females and immatures are green above with rusty flanks and rufous patches at the base of the tail.

If You're Lucky: The True Rarities

Three more species have accepted Iowa records — and unlike Rufous, all three are genuinely one-off. Each has exactly two accepted records, and the Iowa Records Committee's own Accidental designation reflects that directly.

Anna's Hummingbird

Iowa's first record came in fall 2010 at a Saylorville feeder in Polk County — notably, 2010 was also the year Illinois, Michigan, Pennsylvania, South Carolina, and Newfoundland all recorded their own Anna's firsts, part of a broader pattern of eastward vagrancy that year. A second Polk County record followed in November 2015. Nothing since.

Quick ID: The only North American hummingbird with a fully colored crown as well as throat — males glow rose-pink from head to throat. Females show a central patch of rose-red spotting on an otherwise plain throat, with a stocky, broad-tailed build.

Broad-billed Hummingbird

Two accepted IRC records, coded Accidental on the committee's current Rare Bird Review List. A thin but real eBird detection in the 2016–2025 window is consistent with one of the two records falling inside that period, though the exact date and county weren't independently locatable from a primary source this pass.

Quick ID: Named for the field mark that settles it at a glance — a bright red bill tipped in black. Males show a shimmering sapphire-blue throat over an emerald-green body; females are duller, golden-green above and gray below, but carry that same diagnostic red-and-black bill.

Mexican Violetear

Also has two accepted Iowa records, both predating the 2016–2025 eBird window used elsewhere on this page — which is exactly why the species shows zero rows in that dataset despite being a real, committee-confirmed occurrence. Exact dates and counties weren't independently locatable from a primary source this pass; informal, non-citable leads point to 2005 and 2006, but that isn't strong enough to cite directly. 

Quick ID: A larger hummingbird than the rest of Iowa's list, glittering metallic green overall with a violet-blue patch across the breast and a violet ear patch — the field mark that gives the species its name. Sexes look nearly identical.

Iowa Hummingbirds at a Glance

Ruby-throated Hummingbird's dominance here isn't a close call — its statewide eBird frequency peaks near 32%, and every other documented species stays well under 1% at its own peak. With a gap that wide, a bar chart wouldn't show anything the numbers below don't already say plainly, so this section skips straight to the table.

Frequently Asked Questions

How many hummingbird species have been recorded in Iowa?

Five. Ruby-throated Hummingbird is the state's only breeder, Rufous Hummingbird is a regular fall visitor, and Anna's, Broad-billed, and Mexican Violetear Hummingbird are each documented as genuine rarities with exactly two accepted records apiece.

What's the only hummingbird that breeds in Iowa?

Ruby-throated Hummingbird is Iowa's only breeding species, present from late April through fall migration, and overwhelmingly dominant — its statewide eBird frequency peaks near 32%, more than a hundred times higher than any other species.

Is Rufous Hummingbird a rare bird in Iowa?

Not really, despite how often it gets described that way. The Iowa Records Committee classifies it as Casual, not Accidental, and removed it from the official Review List in 2024 — the committee's own language is that it "undoubtedly occurs in Iowa every fall and is chronically under-reported." That's a real, if easy-to-miss, seasonal pattern, not a one-off rarity.

What genuine rarities has Iowa recorded?

Three: Anna's, Broad-billed, and Mexican Violetear Hummingbird, each with exactly two accepted Iowa Records Committee records and nothing recurring — a meaningfully different category from Rufous's regular fall presence.

How can I tell if a hummingbird in my Iowa yard isn't a Ruby-throated?

Start with the throat and the season. Ruby-throated males show a solid red throat in good light; an orange-red body and aggressive feeder behavior in late summer or fall points to Rufous instead. True rarities are almost always confirmed only with a photo or in-hand banding, since they're genuinely uncommon enough that a quick look isn't conclusive.

Why We Created This Guide

Pop's Birding has been helping hummingbird lovers for three generations. One of the questions our customers ask most often is "what hummingbirds actually show up in my state" — we built this guide to give a direct, sourced answer, not a generic one. Most general references either stop at Ruby-throated or lump every other Iowa hummingbird into one undifferentiated "rare visitor" bucket. That misses a real distinction worth knowing: Rufous Hummingbird is a genuine, recurring fall regular, not a one-off rarity, while Anna's, Broad-billed, and Mexican Violetear each have exactly two accepted records and nothing recurring — a status the Iowa Records Committee itself draws a clear line around.

How We Created This Guide

Source and scope. eBird checklist data for Iowa, 2016–2025, pulled statewide plus three representative counties — Linn (Cedar Rapids, east-central), Polk (Des Moines, the capital), and Woodbury (Sioux City, in the far west) — cross-checked against the Iowa Records Committee's (IRC) own current Checklist and Rare Bird Review List.

How we separate a real pattern from a single well-publicized bird. A species clearing a percentage point in eBird's raw data isn't automatically a real pattern — a single well-photographed rarity can draw enough birders to create a real-looking statistic around one bird. Here the more interesting finding ran the other way: Rufous Hummingbird's composite eBird signal is thin and scattered across several near-miss weeks, which could easily read as marginal — but the IRC's own current Review List classifies it as Casual, not Accidental, and explicitly states it occurs every fall. In this case the eBird data understates a real pattern rather than overstating a fake one; we followed the committee's own record, not the raw percentage.

What makes the dominance claim honest. Ruby-throated Hummingbird's lead over every other Iowa species isn't a chart-worthy comparison — its statewide eBird frequency clears the next-highest species by more than 30 percentage points at peak, verified directly against the underlying weekly data rather than assumed from general knowledge of the species. With a gap that wide, a bar chart wouldn't add anything the table above doesn't already say.

Where the sourcing runs thin, we say so. Broad-billed Hummingbird and Mexican Violetear both rest on the Iowa Records Committee's own official Accidental/2-record designation — solid evidence for the tier itself — but we could not independently locate the specific dates and counties behind those records from a primary source this pass. Rather than invent plausible-sounding detail, both species are described here by their confirmed record count only.
