Quick overview: 

The Southeast is where hummingbird migration gets genuinely more complicated than a single arrival date. Ruby-throated Hummingbirds begin arriving on the Gulf Coast as early as late January, with peak spring migration through March across most of the region. But unlike farther north, this region also hosts a true year-round resident — the Buff-bellied Hummingbird — along the Gulf Coast, and a small but reportedly growing number of Ruby-throateds now overwinter here rather than continuing to Mexico, based on winter sighting reports tracked through citizen-science platforms like Project FeederWatch and eBird. Keep at least one feeder up nearly year-round along the Gulf Coast; elsewhere in the Southeast, maintain it through October, since fall migration continues into early October across most of the region.

What Makes This Region Different

The Southeast breaks the simple "everyone arrives in spring, everyone leaves in fall" pattern that holds true farther north. Two things make this region genuinely distinct: it's home to Buff-bellied Hummingbirds, a species that doesn't migrate away from the Gulf Coast at all, and it's seeing an increase in winter Ruby-throated Hummingbird sightings, tracked through citizen-science reporting on eBird and eBird's regional rare-bird alerts — a pattern researchers and birders attribute to milder winters combined with the wide availability of backyard feeders. This region isn't just "warmer and earlier" — it's structurally different in who stays and who goes.

The Hummingbirds You'll See in This Region

Ruby-throated Hummingbird is the most widespread species across the Southeast, present from Virginia and Kentucky down through Georgia, Alabama, Mississippi, and inland Louisiana and Arkansas. Males show the classic iridescent red gorget; females and juveniles are green and white.

Buff-bellied Hummingbird is the Southeast's year-round resident specialty, found mostly along the Texas Gulf Coast and into coastal Louisiana. It's identifiable by its soft tan belly, bright green throat, and distinctive reddish bill — and unlike every other species in this guide, it doesn't have a "migration window" at all in the traditional sense.

Rufous Hummingbird shows up as a fall and winter visitor across much of the Southeast, particularly along the Gulf Coast, sometimes overlapping with overwintering Ruby-throateds at the same feeders.

Migration Timing by Sub-Region

*Texas is covered in more depth in its own dedicated state guide, given its size and species diversity.

Pop's tip: If you're anywhere along the Gulf Coast, don't put your feeder away for winter — between resident Buff-bellied Hummingbirds and a small but increasing number of overwintering Ruby-throateds, this is one of the few places in the country where a feeder genuinely earns its keep in January.

Where They're Coming From, and Where They're Headed

Most Ruby-throated Hummingbirds arriving in the Southeast have just completed one of two demanding journeys: a nonstop, roughly 500-mile crossing of the Gulf of Mexico, or an overland route through Mexico and Texas. Southeast-breeding birds have the shortest onward journey of any Ruby-throated population — many simply stop here rather than continuing north, which is part of why this region sees such early arrivals.

Fall migration follows the reverse path for most birds, fueled by hyperphagia — the intense pre-migration feeding phase where hummingbirds can nearly double their body weight in stored fat. But increasingly, some individuals simply don't make the full trip, staying through winter instead, particularly in milder Gulf Coast microclimates.

How We Know This

Species range, arrival, and departure timing referenced in this guide draw on data compiled by the Cornell Lab of Ornithology's All About Birds and eBird platforms, which aggregate millions of citizen-reported sightings to map real-time migration patterns. The mechanism behind migration timing itself — driven by day length and hormonal changes rather than food or temperature — is confirmed by researchers at the National Audubon Society. The Southeast's growing pattern of overwintering Ruby-throated Hummingbirds is documented by eBird, which has tracked wintering birds becoming regular on Southeastern Christmas Bird Counts, and corroborated by long-term Gulf Coast hummingbird banders who have documented consistent winter site fidelity over nearly three decades of research.

Should I Take My Feeder Down in Fall?

Across most of the Southeast, the standard rule applies: leaving a feeder up does not delay or prevent migration, since timing is driven by day length and hormones, not food availability. But this region has a genuine exception worth knowing: along the Gulf Coast specifically, keeping a feeder up through winter isn't just harmless — it's actively useful, supporting both resident Buff-bellied Hummingbirds and the small but growing number of Ruby-throateds that now overwinter rather than migrate fully south.

Practical recommendation: Gulf Coast residents should consider keeping a feeder up year-round. Everywhere else in the Southeast, maintain it through October, and don't be surprised by an unusually late visitor even into November.

How to Help Hummingbirds Through This Region

• Gulf Coast residents: keep a feeder up year-round rather than seasonally — you may be supporting resident birds, not just migrants
• Everyone else: maintain feeders through at least early October, since fall migration continues later here than in the Northeast
• Watch for winter surprises — an active feeder in December or January anywhere in the Southeast is worth reporting to a local birding platform like eBird, since these sightings help track the overwintering trend as it develops
• Add a comfortable perch or swing near your feeder — hummingbirds spend a large share of their time resting, not flying, and this is true year-round for resident Gulf Coast birds too
• Plant regionally-suited natives — Turk's cap, coral honeysuckle, and firebush all perform well across much of the Southeast and extend natural nectar availability beyond feeder season
• Skip insecticides near feeding areas — hummingbirds rely on small insects for protein, especially when feeding chicks during the region's long breeding season

Frequently Asked Questions

When should I put my hummingbird feeder out in the Southeast? Along the Gulf Coast, as early as late January, since some Buff-bellied Hummingbirds are present year-round and early migrants can arrive that soon. Elsewhere in the Southeast, early-to-mid March is a safe target.

Do all hummingbirds in the Southeast migrate? No. Buff-bellied Hummingbirds are year-round residents along the Gulf Coast, and a small but reportedly growing number of Ruby-throated Hummingbirds now overwinter in the region as well, based on winter sightings tracked through eBird and Project FeederWatch.

Should I keep my feeder up all winter in the Southeast? Along the Gulf Coast, yes — it's increasingly common to see active hummingbird activity there through winter. Elsewhere in the region, feeders are typically taken down after October, though occasional late sightings do occur.

Why are more hummingbirds overwintering in the Southeast now? Milder winters combined with the wide availability of backyard feeders appear to be driving this shift, based on winter sighting patterns tracked through eBird and Project FeederWatch, allowing some Ruby-throated Hummingbirds to survive without making the full migration to Mexico.

What's the best way to help hummingbirds in this region? Keep feeders up longer than you might elsewhere in the country — year-round on the Gulf Coast, through at least October everywhere else — and pair feeders with native, nectar-rich plants suited to your specific part of the Southeast.

Summary: Key Takeaways for Hummingbird Migration in the Southeast

• Buff-bellied Hummingbird is a genuine year-round Gulf Coast resident, unlike any species farther north
• Ruby-throated Hummingbirds arrive as early as late January on the Gulf Coast, with a small but growing number now overwintering rather than migrating fully to Mexico
• Fall departure runs through October across most of the region, later than in the Northeast
• Gulf Coast residents should consider keeping feeders up year-round; elsewhere, maintain through October
• Watch for and report unusual winter sightings, since overwintering patterns in this region are actively shifting
• Timing and species data referenced throughout draw on Cornell Lab of Ornithology (eBird, All About Birds), National Audubon Society research, and Project FeederWatch citizen-science reporting
