New Jersey's hummingbird story is really two stories. One dependable breeder covers the entire state, spring through summer — and then, every fall, Cape May's reputation as one of the East Coast's great migrant funnels turns up something genuinely unexpected. Four rarities have been documented in New Jersey, and knowing the difference between "expected" and "call a bander" is most of what identification here comes down to.

The Hummingbird You're Most Likely to See

Ruby-throated Hummingbird

New Jersey's only breeding hummingbird — and not just for New Jersey. It's the only hummingbird that breeds anywhere in eastern North America, found statewide across the Coastal Plain, Piedmont, and Highlands from mid-April through September. Adult males show a brilliant, iridescent ruby-red gorget that can look flat black without the right light hitting it, paired with an emerald-green back. Females and immatures lack the red throat entirely, showing a plain whitish throat and a rounded, white-tipped tail instead.

Where you are matters for timing. The southern coast reaches reliable Ruby-throated activity about two to three weeks before northern and inland New Jersey catches up — Cape May and Atlantic County are reliably common by the last week of April, while Essex (NYC metro) and Sussex (northwest Highlands) don't get there until the second week of May. See the New Jersey hummingbird calendar for the full county breakdown.

Ruby-throated does not overwinter in New Jersey under normal conditions. Any hummingbird spotted in winter here is almost certainly one of the rarities below.

New Jersey's Fall Rarities: The Cape May Funnel

Cape May's reputation as a migrant funnel isn't just for songbirds and raptors — it's the reason New Jersey's rarity list leans so heavily toward its southern coast. Two species turn up with enough regularity that "rare" doesn't mean "never."

Rufous Hummingbird — the state's most frequent rare visitor

Fall, and sometimes into winter, almost entirely along the coast. Cornell Lab calls it "one of the feistiest hummingbirds in North America" — both sexes are aggressive year-round, not just during breeding season. Adult males are unmistakably coppery-orange with an iridescent orange-red gorget; females and immatures are green-backed with rufous-washed flanks and rufous patches in the tail, virtually inseparable in the field from female Allen's without a close look at the spread tail.

Allen's Hummingbird

The second most frequent rarity, and — like Rufous — concentrated almost entirely in Cape May and Atlantic counties, consistent with the funnel effect. Adult males show a coppery tail, eye patch, and belly against a bronze-green back, with a deep reddish-orange gorget. Females and immatures are extremely difficult to separate from female Rufous; per Cornell, the reliable field mark is tail shape — narrow outer tail feathers on Allen's, broad on Rufous — visible only when the tail is spread.

If You're Lucky: New Jersey's Genuine One-Offs

Beyond the two Cape May regulars, New Jersey has recorded two individual birds so far out of range that each one made state or national birding news. Neither is a species to expect — but both prove that a New Jersey feeder can occasionally produce something remarkable.

Calliope Hummingbird

New Jersey's most notable recent Calliope record didn't come from Cape May at all — a bird overwintered at a private feeder in Point Pleasant, Ocean County, from November 2020 through April 2021. Calliope is North America's smallest hummingbird, with adult males showing a distinctive gorget of magenta rays rather than a solid throat patch; females and immatures have a peachy wash across the underparts and fine green stippling on the throat, per Cornell Lab. A wintering Calliope this far from its normal Rocky Mountain range is a genuine event, not a pattern to expect again.

Broad-billed Hummingbird

New Jersey's only-ever accepted Broad-billed Hummingbird record was a single bird at Heislerville in Cumberland County in November 2022 — proof that truly rare birds can appear almost anywhere in the state, not just the Cape May corridor. Adult males are rich green with a shimmering blue throat and a red bill tipped in black, per Cornell Lab — a genuinely striking combination with nothing else in New Jersey to confuse it with. Females are golden-green above and gray below, with a white line behind the eye.

New Jersey Hummingbirds at a Glance

Frequently Asked Questions

Are there hummingbirds in New Jersey?

Yes — Ruby-throated Hummingbird breeds statewide from mid-April through September, and it's the only hummingbird that breeds anywhere in eastern North America. Four rarities have also been recorded: Rufous, Allen's, Calliope, and a single Broad-billed.

Do hummingbirds stay in New Jersey year-round?

No. Ruby-throated Hummingbirds, New Jersey's only breeding species, do not overwinter in the state under normal conditions. Any hummingbird spotted in winter is almost certainly a rare western vagrant, most often Rufous.

Where in New Jersey am I most likely to see a rare hummingbird?

The southern coast, especially Cape May and Atlantic counties, accounts for the large majority of Allen's and Rufous records, consistent with Cape May's reputation as a migrant funnel. Calliope is the exception — New Jersey's most notable recent record overwintered in Ocean County — and the state's only-ever Broad-billed Hummingbird turned up in Cumberland County, so truly rare birds can appear almost anywhere.

How do I tell Rufous and Allen's Hummingbirds apart?

Adult males are the easier case: Allen's shows a bronze-green back where Rufous is typically solid copper (though some male Rufous also show green backs). Females and immatures are extremely difficult to separate — the reliable field mark is the shape of the spread outer tail feathers, narrow on Allen's and broad on Rufous, which usually requires a photo or a bird in the hand to check.
