South Carolina Hummingbird Season: A Month-by-Month Calendar
South Carolina runs on a real geographic split most timing advice never mentions: Ruby-throated Hummingbird arrives across the whole state every April, but only along the coast — in Charleston and Beaufort — does it genuinely never leave at all. Inland, it's a real, honest migrant, gone by fall like almost everywhere else. Nine more species turn up as documented rarities, one of them (Black-chinned Hummingbird) with a real, recurring winter pattern of its own. Here's how the year actually unfolds, region by region.
The short answer: Ruby-throated arrives statewide in early April and builds to a statewide peak the first week of September. From there, the state splits in two: interior counties (Upstate and the Midlands) empty out by mid-to-late October, a clean, ordinary migrant pattern. Along the coast — Charleston, Beaufort, and largely Horry too — it never actually disappears, dipping to a low winter baseline instead of departing. Rufous Hummingbird is a real, annual winter visitor statewide, strongest November through March.

One thing to know before you start: almost every state's calendar follows a clean "arrives in spring, leaves in fall" shape. South Carolina's coast doesn't. In Charleston and Beaufort specifically, Ruby-throated Hummingbird has real, source-confirmed winter presence every single week of the year — not stragglers, not a rare exception, a genuine year-round population. The "leaves in October" language below applies to most of the state, but not there.
South Carolina's Hummingbird Season at a Glance
Before the region-by-region detail below, here's the whole season in one picture.
How often Ruby-throated Hummingbird shows up on eBird checklists, week by week, statewide, 2016–2025. The statewide shape never truly hits zero — a real signal from the coastal counties folded into the average, not a rounding artifact. Nine more species have been documented in South Carolina. Black-chinned Hummingbird has a real, if thin, recurring winter pattern of its own — see its own chart just below, shared with Rufous. Seven more are true rarities, most with only one to three total accepted records ever: Allen's, Broad-tailed, Broad-billed, Calliope, Buff-bellied, Anna's, and Blue-throated Mountain-gem (this last one on a lower-confidence "Provisional" status — written documentation only, no photo or specimen). Full details on each are in the Sources section below.
Rufous and Black-chinned are both real winter specialists here, and — genuinely unusually — close enough in scale to share one honest chart without either one crushing the other.
Rufous Hummingbird — a real, annual winter visitor, not on South Carolina's official review list at all, unlike every other western hummingbird here — and Black-chinned Hummingbird, technically a Rare-tier species by committee classification, but with genuine multi-year recurring evidence behind it (Christmas Bird Count records from two separate winters, Hilton Pond Center banding records). Both peak at the same 0.2% of checklists and track closely together, strongest November through March. Source: same eBird pull as above.
Regions covered in this guide
York (Rock Hill), Greenville, Richland (Columbia), Horry (Myrtle Beach), Charleston, and Beaufort — chosen to represent South Carolina's three real climate zones: Upstate, the Midlands, and the coast.

March: The Quiet Tail End
March is the closest South Carolina gets to a true off-season, though even here it's not quite empty. Ruby-throated sits at its statewide low, still weeks from its real arrival — but the coast tells a different story, where the population that never left continues at its usual quiet baseline. Rufous and Black-chinned are both fading out too, their winter presence tapering toward the lowest point of their year. By the final week of the month, the first real hint of the spring wave starts to show statewide.
| Region | Status |
|---|---|
| Upstate & Midlands (York, Greenville, Richland) | Still quiet — real arrival hasn't started |
| Coast (Horry, Charleston, Beaufort) | Winter baseline continues — the population never left |
April: The Whole State Arrives
April is when South Carolina's real spring wave lands. York and Richland show their sustained climb first, in the opening week; Greenville follows about a week behind. Along the coast, arriving birds don't start a season from zero — they join the population that's been there all along, which is why coastal numbers climb faster here than almost anywhere else in the state this month. By month's end, Rufous and Black-chinned have both faded out completely; whatever's visiting a feeder in late April is Ruby-throated.
| Region | Status |
|---|---|
| York | Real arrival, first week of April |
| Richland | Real arrival, first week of April |
| Greenville | Real arrival, second week of April |
| Coast (Horry, Charleston, Beaufort) | Arriving birds join the resident population — numbers climb fastest here all year |
What to do: have a feeder out statewide by the first week of April — the wave lands fast almost everywhere.
Shop AspenPerch® →May: Ruby-throated Has the State to Itself
By May, arrival is complete and territories are settling in everywhere. This is genuinely a single-species month for South Carolina — both winter specialists have dropped to true zero statewide, not just rare, so whatever's at a feeder in May is Ruby-throated, full stop.
June: Nesting Season
June brings a real, small dip in the data before the climb resumes — the same pattern that shows up almost everywhere Ruby-throated breeds, as incubating and brooding females visit feeders less often. It's not a sign birds have left; nesting season simply looks quieter by nature. Rufous and Black-chinned remain completely absent.
| Region | Status |
|---|---|
| Statewide | Nesting season underway; a real dip, then steady climb toward the fall peak |
Why nesting season is the demanding one
There's a wrinkle specific to hummingbirds. Most female birds build up a temporary calcium store in their bones, called medullary bone, and draw on it to make eggshell. Hummingbirds have very little of it, so a laying female has less in reserve. Researchers have seen nesting females eating wood ash and other mineral-rich materials, which they think helps replace the calcium that goes into eggs. In one 1994 study, every bird seen eating ash was a female tending a nest.
It's part of why Pop's Nectar includes calcium and electrolytes rather than sugar alone. Nesting females need extra calcium during egg-laying, and plain sugar water has essentially none. Read more on the research behind it.

Like May, July belongs to Ruby-throated alone — the two winter specialists are still completely absent and won't return until fall. What July actually brings is heat, climbing steadily through the month, and with it the same pest pressure every Southeastern state deals with this time of year.
What to do: keep pests off without pesticides — AspenPerch®'s ant moat + HummGuard® keep ants, bees & wasps out without costing the birds their insect-protein source.
Shop HummGuard® →August: Fueling Up
Ruby-throated is deep into its pre-migration fueling now, climbing steadily toward September's real peak. The two winter specialists are still essentially absent this month — a single data point that shows up for each sits right at eBird's reporting floor, not a genuine early arrival, so don't expect real Rufous or Black-chinned activity before their real season gets underway in November.
What to do: keep everything full — birds are fueling for a long flight.
September: The Peak, Then the Turn
September opens at the year's real peak — 35% of checklists in the first week alone — then turns fast. By the last week of the month, statewide numbers have already dropped by nearly a quarter from where they started.
| Region | Status |
|---|---|
| Statewide | The year's real peak — 35% of checklists, first week of the month — then a fast decline begins everywhere |
October: The State Splits in Two
The decline that started in September keeps going fast — statewide numbers drop by nearly 90% across the month alone. But how that decline actually plays out depends entirely on where you are. Inland, it's a clean, ordinary departure. On the coast, it's not a departure at all, just a real dip toward the same low baseline the population holds all winter.
| Region | Status |
|---|---|
| York, Greenville, Richland | Leaving fast — most gone by late October |
| Coast (Horry, Charleston, Beaufort) | Numbers ease down toward the winter baseline — not a departure, a real dip |
What to do: sow wildflower seed while the ground is still warm.

By November, the split from October has settled into its winter shape — gone completely inland, present at a steady low baseline on the coast. Meanwhile, Rufous's real winter build gets underway statewide, still small in number but genuinely climbing week over week rather than the noise seen back in August.
| Region | Status |
|---|---|
| York, Greenville, Richland | Ruby-throated gone for the year |
| Coast (Horry, Charleston, Beaufort) | Ruby-throated continues at its low winter baseline |
| Statewide | Rufous's real build gets underway |
What to do: a wintering western visitor is territorial — a second feeder + swings spaced apart help if one bird claims the whole station.
Shop a second swing →December: Building Toward the Real Peak
December is genuinely a build month, not the peak itself, however it might look on the way up. Rufous climbs steadily across the month, and Black-chinned's own winter pattern builds right alongside it — both still short of where they'll actually crest, which doesn't happen until January.
| Region | Status |
|---|---|
| York, Greenville, Richland | No Ruby-throated at all |
| Coast (Horry, Charleston, Beaufort) | Ruby-throated present all winter, real and confirmed |
| Statewide | Rufous and Black-chinned both building, neither at its real peak yet |
January: The Real Peak
January, not December, is when South Carolina's two winter specialists actually crest. Rufous peaks in the second week of the month; Black-chinned follows right behind it in the third — both cresting at right around 0.2% of checklists before beginning their own slow decline toward spring. Along the coast, Ruby-throated continues exactly as it has all winter, unaffected by either of the other two species' timing.
What to do: keep nectar fresh through cold snaps — a real bird is counting on it, whether that's a coastal Ruby-throated or a wintering Rufous or Black-chinned. Our winter hummingbird feeder care guide covers heated feeders and the two-feeder swap.
February: The Closing Chapter
By February, both winter specialists are past their peak and declining again — Black-chinned faster than Rufous, already down to a bare trace by month's end. This is functionally the closing chapter of the winter story, with March's true quiet stretch just ahead.
Frequently Asked Questions
When do hummingbirds arrive in South Carolina?
Early April almost everywhere — York and Richland lead by the first week, Greenville about a week behind. Along the coast, "arrival" means new birds joining a population that's already there.
When do hummingbirds leave South Carolina?
Most of the state is quiet by late October. The real exception is the coast — Charleston, Beaufort, and largely Horry — where Ruby-throated Hummingbird never actually leaves, dipping to a low winter baseline instead.
Are there hummingbirds in South Carolina in the winter?
Yes, in two different ways. Along the immediate coast, it's the same Ruby-throated Hummingbird that never left. Statewide, Rufous Hummingbird is a genuine, annual winter visitor — real enough that South Carolina's own bird records committee doesn't require documentation for it, unlike every other western hummingbird species that shows up here.
Why do hummingbirds stay all winter in Charleston and Beaufort but not the rest of the state?
It's a real, documented pattern, not a fluke — Audubon Christmas Bird Count data shows a broad, recurring, multi-year, multi-county presence along the coast (48 Ruby-throated across 7 counts in one recent year alone), while inland counties show a genuine, sustained multi-week absence every winter. The likely explanation is coastal habitat and climate — milder temperatures and more consistent winter nectar sources near the immediate coast — though the exact mechanism isn't something eBird data alone can confirm.
Should I keep a feeder up through a South Carolina winter?
Yes, almost anywhere in the state — genuinely essential if you're near the coast, and a good idea at low odds everywhere else, since Rufous shows up statewide. Keep nectar fresh through cold snaps rather than assuming an empty-looking feeder in January means nothing's coming.
Why We Built This Calendar
Pop's Birding has been helping hummingbird lovers for three generations. One of the questions our customers ask most often is "When do hummingbirds arrive and leave my state?" — we built this calendar to give a direct, sourced answer, not a generic one. Most timing advice online gives a single date for an entire state, which is exactly wrong for South Carolina: a coastal county and an Upstate county don't share a season, and averaging them together would hide the state's single most interesting finding entirely. We wanted a calendar that tells you the truth for where you actually live, not an average that's wrong for a third of the state.
How We Built This Calendar
We checked every rare species against the South Carolina Bird Records Committee's review list, not eBird frequency alone. Rufous isn't on the list at all, which marks it as a regular visitor, while Black-chinned and seven others need documentation for every report, which marks them as true rarities even when their eBird numbers look bigger. The real finding: South Carolina's Ruby-throated population is two stories, not one. Six of the nine counties tracked show an ordinary migrant pattern, arriving in April and gone by fall. Three coastal counties never show a real absence, which Audubon's Christmas Bird Count records confirm across multiple winters. A single statewide average hides that completely.
