If you are waiting on hummingbirds in Oklahoma, the honest answer depends on which end of the state you are standing in — and the gap is wider than most people expect. The first hummingbirds of the Oklahoma year reach Lawton about a month before Tulsa sees one, and they are not even the same species.

The short answer: the first birds show up in southwest Oklahoma in the last week of March, and they are Black-chinned Hummingbird, not the Ruby-throated Hummingbird most of the state knows. Ruby-throated reaches everywhere else through April. Most of Oklahoma empties out by early October, though the southwest holds birds into late October. And out in the Panhandle, the state's common hummingbird barely turns up at all.

Oklahoma's Hummingbird Season at a Glance

Two charts, because Oklahoma's season is really two stories — the one almost everyone sees, and the one the statewide numbers bury.

Statewide reporting rates by week, from eBird checklist data (Cornell Lab of Ornithology), 2016–2025.

That chart tells you who is biggest, but it hides who is smallest. Ruby-throated's late-August peak flattens everything else into what looks like a flat line — even though two other birds have a real, tight, repeating season of their own. Here they are again at their own scale, so a bird you would never spot above still shows its actual shape below.

Rufous and Calliope Hummingbirds, statewide, shown April through November — January to March and December are empty for both. Same eBird data, 2016–2025.

January & February: The Quiet Stretch

Oklahoma is genuinely empty in these two months. There is no breeding species present anywhere in the state, and February in particular has no real signal at all. The one exception is around Lawton, where a scattering of January records shows up across the years — single birds, not a pattern, and thin enough that we would not build a plan around them. Anywhere else, a hummingbird at an Oklahoma feeder in midwinter would be a genuine rarity worth reporting.

What to do: nothing urgent, and that makes this the right stretch to strip feeders down and clean them properly rather than watch them. If you keep one up year-round, southwest Oklahoma is the one part of the state where that has occasionally paid off in January.

March: The Southwest Goes First

This is the most under-appreciated month in the Oklahoma hummingbird year. In the last week of March, Black-chinned Hummingbirds arrive around Lawton in real numbers — not a first-bird trickle, but a genuine arrival with dozens of checklists behind it. Nowhere else in the state has anything yet. Oklahoma City sees the very first trace at the end of the month; Tulsa, the southeast and the Panhandle are all still waiting.

The species matters as much as the timing. The bird arriving in southwest Oklahoma in March is not an early Ruby-throated — it is a different hummingbird with a different range, and it will remain the dominant bird in that part of the state right through the summer.

April: Ruby-throated Reaches the Rest of the State

Ruby-throated's real arrival, and it does not happen on the same week statewide. The southeast goes first, Oklahoma City follows mid-month, and Tulsa and the Panhandle bring up the rear in the last week or so. Around Lawton, Ruby-throated simply joins the Black-chinned that have already been there for a month.

"Arrival" here means the first week a region's reports climb clearly above the winter baseline and hold there — not a one-week blip. We checked the actual number of checklists behind each of these, not just the percentage, and required the pattern to hold for consecutive weeks before calling it real.

It's part of why Pop's Nectar includes calcium and electrolytes rather than sugar alone. Nesting females need a real source of calcium during egg-laying, and there isn't one in nectar alone — and in southern Oklahoma, nesting is already underway while the north is still waiting on its first arrivals.

May: The Spring Peak, Not the Summer One

May is busy everywhere, and it catches people out. Ruby-throated hits a strong spring high around Tulsa, and Black-chinned reaches its Panhandle peak for the year — the busiest Cimarron County gets until August. It looks like the top of the season.

It is not. Numbers dip through June before climbing to the real high in late August. If your feeder goes quiet in a few weeks, nothing has gone wrong.

June: The Nesting Lull

The quietest month of the active season, and the most misread. Fewer birds at the feeder in June usually means more birds sitting on nests nearby — activity drops because females are incubating, not because the birds have moved on. Every region holds its birds; they are simply less visible.

A quiet feeder in June is the moment to add a second one, not to take the first down. Once broods fledge in July the traffic roughly doubles overnight, and a single station becomes something for one bird to guard rather than something several can use. A second feeder placed out of sight of the first is the simplest fix there is. Shop AspenPerch® →

July: The Western Birds Start Moving

Numbers climb hard everywhere, and Black-chinned peaks for the year around Lawton in the last week of July. But the real event is out west: in the final week of the month, Rufous and Calliope Hummingbirds appear in the Panhandle, the leading edge of a genuine western migration that has nothing to do with Oklahoma's breeding season.

July is also when Oklahoma summers turn serious — the western half of the state sees thirty to forty days above 100°F in a typical year — and heat is what spoils nectar. Change it more often than feels necessary.

Keep pests off without pesticides — hummingbirds rely on small insects for protein, so spraying near a feeder can cost them a food source, not just protect one.

August: The Busiest Month in Oklahoma

The statewide peak, and it is not close — Ruby-throated reaches 31% of all Oklahoma checklists in the last week of August. The southeast runs highest of anywhere in the state, with roughly a third to a half of checklists carrying the species through late summer. Tulsa and Oklahoma City both peak in the same week.

Out in the Panhandle, August is a different event entirely. Rufous and Calliope both peak, moving through together in a tight three-week pulse alongside the resident Black-chinned. It is the one stretch of the year when the western half of the state has more hummingbird variety than the eastern half.

Seeing one bird chase everyone else off? That's usually a resident claiming both the feeder and a nearby swing as its own guarded territory — and Rufous Hummingbird, arriving now, is famous for it. A second feeder and a second swing, spaced out of sight of each other, gives the incoming migrant its own station to guard instead of fighting over one. Shop a second feeder →  |  Shop swings →

September: Peak Holds, Then They Leave

The first half of September is still very busy — the southeast is at its highest of the year in the opening week. Then the turn comes, and it comes fast. By the end of September most of Tulsa, Oklahoma City and the southeast have emptied out, and the Panhandle's Black-chinned have gone entirely. Around Lawton the Black-chinned leave through the month while Ruby-throated linger behind them.

The birds you see now are often not the ones that nested in your yard. Ruby-throated moving through Oklahoma in September are heading for a long flight, and everything they take on is fuel for it.

This is the month to be generous, not economical. Birds fueling for a long flight need feeders topped up more often — the large 2lb Nectarlyte® powder or the Nectarade® liquid concentrate keeps you from running out mid-surge. Shop Nectarlyte® 2lb →  |  Shop Nectarade® Concentrate →

October: Most of Oklahoma Empties Out, and It's the Planting Month

The Panhandle is already done — its season ended in September. Tulsa and the southeast hold a thin first week and then the last of them leave. Oklahoma City drops away through the first half of the month. The exception is the southwest: around Lawton, Ruby-throated do not leave until the second half of October, making it the last part of Oklahoma with birds in it, just as it was the first to get them.

What to do: do not pull your feeders the moment the regular birds leave. The second half of October is exactly when a late straggler or a western rarity turns up, and an empty hook is a missed one.

This is the planting month. Sow now and native wildflowers get the cold, moist period most varieties need to bloom reliably next spring. Shop the Perfect Little Sanctuary® blend →

November & December: Winter Watch

The Panhandle, Tulsa and the southeast are empty. Around Lawton, scattered late birds show up into November and December — thin, but consistent enough across the years to be worth a feeder. And around Oklahoma City, this is the window when the state's genuine western rarities have turned up.

That is the case for leaving one feeder going. Oklahoma's rarest hummingbirds — the ones that make a state records committee sit up — have mostly been found at ordinary backyard feeders in late autumn and winter, by people who simply had not taken theirs down yet.

The Year at a Glance

Frequently Asked Questions

When do hummingbirds come back to Oklahoma?

Around Lawton and the southwest, the last week of March — and the first ones back are Black-chinned, not Ruby-throated. The rest of the state follows through April: the southeast first, Oklahoma City in the middle of the month, then Tulsa and the Panhandle in the last week or so. If you want one date to plan around, get a feeder out in mid-March in the southwest and late March everywhere else.

When do hummingbirds leave Oklahoma?

Faster than most people expect. The southeast and the Tulsa area both lose most of their birds by late September, and Oklahoma City follows in early October. The exception is the southwest — around Lawton, Ruby-throated hang on into the second half of October, making it the last part of the state with birds. The Panhandle is the earliest to empty, with its Black-chinned gone by the end of September.

How long do hummingbirds stay in Oklahoma?

It depends where you are, and the spread is about two months. Around Lawton the season runs from late March to late October — roughly seven months, the longest in the state. In the Panhandle it is late April to late September, closer to five. Most of the rest of Oklahoma gets about six months, from early or mid-April into early October.

When should I put my hummingbird feeder out in Oklahoma?

Mid-March in the southwest, late March everywhere else. Being a week or two early costs nothing; being a week late costs you the first arrivals. A feeder that is already out when the first bird passes through is what makes a yard a stop on the route rather than somewhere it flies over.

When should I stop feeding hummingbirds in Oklahoma?

Later than most people do. Leaving a feeder up does not hold birds back from migrating — that is driven by daylight, not by whether your feeder is full — and late birds moving through still need the fuel. Keep at least one going into November. If you are willing to leave one up through the winter, that is how most of Oklahoma's genuine rarities have been found.

Why are the hummingbirds different in the Oklahoma Panhandle?

Because the Panhandle has more in common with the Rocky Mountain foothills than with eastern Oklahoma, in every way that matters to a hummingbird. Ruby-throated is an eastern bird that follows trees and moisture, and out at Black Mesa there is little of either — annual rainfall is about 17 inches, against roughly 56 in the southeast corner. What you get instead is Black-chinned as the everyday bird, and a real western migration passing through in late summer.

Why We Built This Calendar

Pop's Birding has been helping hummingbird lovers for three generations, and one of the questions our customers ask most often is simply "when do they come back?" For Oklahoma, almost every answer online gives a single date for the whole state. That is exactly wrong for a place shaped like this one. The first hummingbirds of the Oklahoma year reach Lawton a full month before Tulsa sees one, and they are a different species. A single statewide date would be misleading for most of the people reading it, so we built a calendar that tells you the truth for where you actually live.

How We Built This Calendar

The timing here comes from eBird checklist data (Cornell Lab of Ornithology) for 2016 through 2025, pulled in August 2026. Rather than average the whole state, we followed five counties chosen for real climate and landscape differences rather than population: Cimarron in the Panhandle, Tulsa in the northeast, Oklahoma in the center, Comanche around Lawton, and McCurtain in the far southeast. The Oklahoma Climatological Survey puts annual rainfall at about 17 inches in the western Panhandle against about 56 inches in the far southeast, and the Environmental Protection Agency maps twelve distinct ecoregions inside the state — so a five-county spread is the minimum honest way to describe it.

For arrivals and departures we did not simply take the first week a species appeared. A single checklist can put a bird on the map without meaning the season has started, so we counted a week only when reporting cleared a real threshold, was backed by a meaningful number of checklists, and held for consecutive weeks. That distinction did real work here: it removed a scattering of thin winter records around Lawton that would otherwise have made southwest Oklahoma look like it had hummingbirds year-round, and it caught a single-week October reading that would have put Ruby-throated's southwestern peak in the wrong month entirely.

The finding that surprised us was that Lawton has the longest hummingbird season in Oklahoma and neither end of it belongs to the same bird. Black-chinned arrives there in late March, weeks ahead of anywhere else, and then Ruby-throated holds on into late October after the Black-chinned have gone. Most states have one species defining both ends of the season; southwest Oklahoma has a handoff. That also settles what looks like a contradiction in the published advice — the Oklahoma Department of Wildlife Conservation says hummingbirds begin arriving in mid-March and early April, while the checklist data says late April for much of the state. Both are right. They are describing different species.

We built two charts rather than one because a shared scale cannot hold this state. Ruby-throated peaks near a third of all checklists; Oklahoma's western migrants peak below half a percent, which on one chart is a flat line. On its own chart, at its own scale, that group turns out to have a tight, repeating late-summer window — which is the actual answer to "what is that hummingbird at my feeder in August that doesn't look right." What is original here is the county-level comparison and the finding that came out of it. This is not a restatement of eBird's own bar charts, and it is not a national average with Oklahoma written at the top.
