Massachusetts Hummingbird Season: A Month-by-Month Calendar
Timing derived from eBird data, 2016–2025 (sourced July 2026)
Massachusetts has the shortest and most sharply defined hummingbird season of any state we've mapped. An arrival that goes from zero to everywhere in about three weeks, a quiet stretch in June that fools people every year, and a peak that catches almost everyone out.
Massachusetts's Hummingbird Season at a Glance
How often each species turns up on eBird checklists, week by week — statewide, 2016–2025.
The short answer: they return in the last week of April, peak in the final week of August, and are gone by early October — about five months. From November through March there are none at all.
| Question | Answer |
|---|---|
| When do they arrive? | Last week of April |
| When should feeders go up? | Last week of April, statewide |
| When do they nest? | May through July; usually one brood |
| When is the peak? | Final week of August |
| When do they leave? | Through September; gone by early October |
| How long do they stay? | About five months |

One state, one window
Unlike the bigger states in this series, Massachusetts doesn't need regional calendars. From the Berkshires to Nantucket is under 190 miles, and the arrival spread across that distance is a matter of days. Where the west does differ is in breeding density — the Berkshire highlands hold the state's highest concentration of nesting hummingbirds, and Cape Cod and the Islands are among the lowest.
January & February: The Season Is Closed
Empty — with one asterisk.
| Statewide | No hummingbirds in ten years of records. The season is genuinely closed. |
| The asterisk | A handful of western vagrants have survived New England winters at maintained feeders. One Rufous stayed in South Orleans from December through late March; another pair wintered in Orleans into March. |
What to do: Nothing, unless you already have a bird. If you do have a hummingbird at a Massachusetts feeder in January, you have something genuinely rare — keep the nectar from freezing, and get in touch with a local birding group.
March: Still Nothing
| Statewide | Zero. The birds that will nest here are still in Central America or working their way up the Gulf Coast. |
What to do: A good month to clean and check your feeders, and to get columbine in the ground if you're planting.
April: The Season Opens in the Last Week
The season opens in the last week.
| Weeks 1–2 | Nothing yet. |
| Week 3 | The very first reports appear — a trickle, and only just. |
| Week 4 | Hang your feeders. First arrivals proper. Mass Audubon's own advice is the last week of April, and this is why. |
Pop's tip: Males arrive first and spend a week or two claiming territory before the females follow. So a feeder that sits untouched through the first days of May isn't a failed feeder — it's an early one. Hummingbirds have exceptional spatial memory, and the feeder that's already there when they arrive is the one they'll come back to next year.
May: Zero to Everywhere in Three Weeks
| Week 1 | Reports jump fivefold in seven days. |
| Week 2 | Nearly double again. Females arriving now. |
| Week 3 | Spring high point. This is as visible as hummingbirds get until August. |
| Late May | Numbers start easing as birds settle onto territory. Nesting is underway. |
What to do: Keep it full — this is the month a new feeder gets found. And if you plant one thing, make it eastern red columbine: it blooms now, exactly when the birds land.
June: The Lull That Fools Everyone
| Statewide | Reports drop by about a third from the May high and sit flat all month. |
| Why | Females are sitting on nests. A hummingbird incubating two eggs leaves for only a few minutes at a time — she's still there, just not where you can see her. |
What to do: Don't take a quiet June feeder as the season ending. It's the middle of the breeding season, and the busiest stretch of the year is eight weeks away. Skip the insecticide too — nesting females need small insects and spiders for protein, and spider silk is what binds the nest together. If wasps are the problem, HummGuard™ nectar tips handle it without spray.
Why nesting females go looking for minerals. Most birds bank calcium in medullary bone and draw on it while laying — hummingbirds don't have that reserve, so an egg-laying female has to find calcium as she needs it, from a diet that's almost entirely sugar. It's why Pop's Nectar includes calcium and electrolytes rather than sugar alone; the research behind that includes field observations of nesting females eating wood ash, which is 50–75% calcium oxide.
July: The Young Start Flying
| Statewide | Climbing steadily all month as fledglings join the adults at feeders. |
| Departures | Some adult males are already leaving. Their part of the season ends first. |
What to do: Add a second feeder if you're seeing chasing. Hummingbirds defend food they can see all of, so two placed out of sight of each other support far more birds than one — and you'll need the capacity next month.
August: Peak of the Year
The biggest month of the year, and it ends the season.
| All month | Climbing week on week to the year's high point in the final week of August. |
| Who's here | Mostly females and this year's young, fueling for the trip. Many adult males have already gone. |
| Why so early | Georgia and Alabama peak in September, Florida in October. New England birds start earlier because they have farther to travel. |
What to do: Be generous. This is the month that matters most, and it's also the month most people have stopped paying attention.
September: A Fast, Orderly Exit
| Week 1 | Still busy, just off the peak. |
| Weeks 2–4 | Falls away by roughly half each week. By month's end there's very little left. |
| Berkshires | A few days ahead of the coast, as in spring. |
What to do: Keep it up. The last birds through are usually that summer's young making the trip for the first time, and a feeder left standing does not delay anyone — hummingbirds migrate on day length, not food supply.
October: Effectively Over by Week One
| Week 1 | A final scattering of stragglers. |
| Rest of month | Essentially nothing. |
| Planting | Prime wildflower sowing window opens — aim for around the first frost. |
What to do: Leave one feeder up into early October for the last stragglers, then bring it in before hard freezes become common. Frozen nectar can injure a hummingbird's bill. And sow the Perfect Little Sanctuary® blend now — Massachusetts winters give most of the varieties exactly the cold, moist stratification they need.
November & December: Vagrant Season
Season over — and the most interesting months for a birder.
| Statewide | Ruby-throated are long gone. |
| Cape Cod & the Islands | Vagrant season. Black-chinned records cluster from late October to mid-December. Calliope records run late October through December. Rufous can appear any time from late July onward and occasionally stay all winter. |
Why November is when Massachusetts gets interesting
Every one of the state's six accepted hummingbird species except Ruby-throated is a western or southwestern bird that has no business being here. Almost all of them are found in late fall or early winter, and almost all on Cape Cod, Nantucket, or Martha's Vineyard.
They're found because somebody left a feeder up. The state's only Broad-billed Hummingbird spent from late August to early December 2008 in a Dennis garden. If something turns up at your feeder in November, photograph it and tell a local birding group — female and immature hummingbirds usually can't be named without a licensed bander measuring them in the hand. Our Massachusetts species guide covers all six and how to tell them apart.

Frequently Asked Questions
When do hummingbirds return to Massachusetts?
The last week of April. The very first reports appear in the third week, but the season opens properly in the fourth — which is why Mass Audubon recommends feeders go out then.
When do hummingbirds leave Massachusetts?
Numbers fall away through September, roughly halving each week after the first, and by early October there's very little left. A final scattering of stragglers passes through in the first week of October.
How long do hummingbirds stay in Massachusetts?
About five months — late April through September. It's the shortest and most sharply defined hummingbird season of any state we've mapped.
When do hummingbirds lay eggs in Massachusetts?
Nesting runs May through July. The female incubates two pea-sized eggs for around two weeks and feeds the young for another three. In New England's shorter season she'll usually manage one brood, occasionally two.
Why is my hummingbird feeder quiet in June?
Because females are sitting on nests. Reports drop by about a third from the May high and stay flat all month. A hummingbird incubating eggs leaves for only a few minutes at a time — she's still there, just not where you can see her.
How We Built This Calendar
The month-by-month pattern comes from ten years of citizen-science observation rather than general guidance. We pulled eBird bar chart data for Massachusetts covering 2016 through 2025 — more than 1.8 million submitted sighting lists — and read the seasonal shape directly off the reporting rates. Feeder timing and nesting biology are cross-checked against Mass Audubon, and rarity records against the Massachusetts Avian Records Committee.
We looked at whether Massachusetts needed separate regional calendars and concluded it doesn't. Across a state under 190 miles wide, the arrival difference between the Berkshires and the coast is a matter of days, not weeks — not enough to justify separate schedules.
Percentages describe how often a species appears on birdwatchers' submitted sighting lists — a measure of how likely you are to encounter one, not a population count.
