How to Attract Hummingbirds in Maryland: A Backyard Sanctuary Guide

Here's some genuinely good news buried in Maryland's wildlife data: unlike many hummingbird populations across North America, Ruby-throated Hummingbird numbers in Maryland climbed steadily from 1966 all the way to 2014. In a world where a lot of bird conservation news trends the wrong direction, this is one story that's actually been heading up.

Whether you're gardening in Baltimore, Annapolis, the Eastern Shore, or Western Maryland, this guide will walk you through everything you need to turn your space into a Maryland hummingbird destination: who's around and when, how to size your setup to any space, feeder and nectar care, pest-safe cleaning, and the native plants and wildflower seed varieties that thrive in Maryland's climate.

The short version, if you're in a hurry:

To attract hummingbirds in Maryland, put up a leak-proof feeder filled with fresh, dye-free nectar by mid-April in Southern Maryland and late April elsewhere, keep it clean and refilled every 1–6 days depending on heat, skip the insecticide so hummingbirds can still hunt insects for protein, and plant native, nectar-rich flowers like cardinal flower, eastern red columbine, and coral honeysuckle so your yard offers real food alongside the feeder.

• Species you'll see: Ruby-throated breeds here; Rufous is a genuine, non-review fall-and-winter visitor; five more — Black-chinned, Calliope, Allen's, Anna's, and Mexican Violetear — are accepted rarities, two still recurring and three genuinely historic
• Best feeder type: leak-proof design with a comfort perch, like the AspenPerch® Hummingbird Feeder
• Best nectar: plain 4:1 water-to-sugar ratio, no red dye — or Pop's Nectar with added electrolytes and calcium
• Feeder timing: up by mid-April in Calvert County and Southern Maryland; late April everywhere else, since males start arriving and establishing territory around that time
• Nectar change frequency: every 1–2 days above 90°F, every 5–6 days below 70°F
• Pest control: no insecticide — use vinegar-water spray and HummGuard® nectar tips instead
• Top native plants: cardinal flower, eastern red columbine, coral honeysuckle, trumpet creeper, bee balm
• Best wildflower planting window: October through November, for spring bloom timed to spring migration

Which Hummingbirds You'll See in Maryland

Maryland's hummingbird scene is dominated by one dependable breeder. Ruby-throated Hummingbird is the state's only nesting species, present from April through September and responsible for nearly every hummingbird sighting most Marylanders will ever have — and a genuine bright spot in bird conservation, with the state's population climbing steadily from 1966 to 2014. Rufous Hummingbird is Maryland's other non-review species: an uncommon but increasingly regular fall-and-winter visitor, most reliably reported around Bethesda in Montgomery County, and famously territorial at a feeder.

Five more species are on Maryland's official checklist, each a formal review bird. Black-chinned Hummingbird has been documented in three separate recent years — 2020, 2021, and December 2025 — all clustered in Southern Maryland's Calvert County. Calliope Hummingbird, North America's smallest species, had seven accepted records as of 2018 and has continued to turn up since, mostly in the far-western mountains of Garrett County. The other three are true historic rarities: Allen's Hummingbird has one confirmed record, settled by DNA testing in 2008, plus one documented but unconfirmed 2011 sighting; Anna's Hummingbird has two accepted records, from 2006–07 and 2010; and Mexican Violetear has two records, both from a single two-week window in October 2011.

When Do Hummingbirds Arrive and Leave Maryland?

Ruby-throated Hummingbirds arrive across Maryland within a fairly consistent window each spring, with the first birds sometimes showing up as early as mid-April and most gone by mid-October — though a few linger through winter near the coast.

Arrival and Departure by Region

Arrival and departure windows by region, based on eBird checklist data (Cornell Lab of Ornithology), 2016–2025. See our Maryland hummingbird calendar for the full month-by-month breakdown.

Calvert County in Southern Maryland runs slightly ahead of the rest of the state, with birds arriving mid-April instead of late April elsewhere. On the departure end, Worcester County on the Atlantic coast empties out earliest, by late September, while Calvert holds on longest, into mid-October — the same county that also produces the state's most reliable Black-chinned Hummingbird records.

Attracting Hummingbirds No Matter Your Space

You don't need acres of land to invite wonder into your yard. Hummingbirds are famously adaptable — all they're really looking for is a dependable food source, a safe place to perch, and a little color.

• Small patio or balcony: One feeder hung from a bracket or shepherd's hook, paired with a container of cardinal flower or coral honeysuckle, is plenty to get noticed. Hummingbirds are solitary feeders by nature, so a single feeder works great in tight spaces. See our guide to what hummingbird products work best on a small patio or balcony for more.
• Average backyard: Add a mix of feeders and native blooms along a fence line or garden bed, and give your visitors a swing or two nearby to rest and survey their territory between sips.
• Large yard with trees: Take advantage of the shade. Hummingbirds prefer feeders and plantings tucked out of harsh, direct afternoon sun, with a nearby branch to perch on and watch for rivals. Spiders are especially valuable in a hummingbird-friendly yard — their silk is essential material for nest construction, so avoid clearing away every web you find.

Choose a Saucer Type Feeder to Prevent Leaks

A feeder is only as good as what's in it — and how well it's kept. A leaky feeder does more than waste nectar: it can attract ants, bees, and other pests — turning your sanctuary into a mess that can deter hummingbirds.

Saucer-style feeders, like our AspenPerch® feeder, hold nectar in a shallow basin below the ports, so there's no sealed air pocket to cause problems; bottle-style, gravity-fed feeders tend to leak more, especially in hot weather, since the air trapped above the nectar expands with heat and pushes nectar out through the ports. Maryland DNR also recommends choosing feeders without yellow attachments, which can attract unwanted wasps.

Keeping your feeder filled is also important because hummingbirds need a dependable, fresh source they can count on every visit, not a gamble.

Keep Feeders Clean with Fresh Nectar

Clean your feeder every time you change the nectar, using warm water and a bottle brush — no soap residue, no bleach or harsh commercial cleansers. A little vinegar and water solution works great for breaking down sticky buildup or the beginnings of mold. Maryland's own wildlife officials recommend cleaning feeders at least twice a week during summer — mold and bacteria buildup can be deadly to hummingbirds, so don't stretch this out longer than necessary.

Skip the Red Dye

Your feeder's color does the attracting; dyed nectar offers no benefit and can be harmful to a hummingbird's health.

Only Fill Enough to Change Often

An 8 oz feeder rarely needs to be topped all the way off — overfilling just means more nectar sitting around long enough to spoil. A better approach is to fill only enough that your hummingbirds empty your feeder every couple of days.

How Often to Change Nectar in Maryland

Sugar water ferments faster the hotter it gets. Use this as your rule of thumb:

If the nectar ever looks cloudy before that window is up, change it early — cloudiness means it's already started to ferment.

Keeping Feeders Pest-Free Without Insecticide

Hummingbirds don't live on nectar alone — small insects make up a big part of their protein diet, especially for feeding chicks. That means insect spray is off the table around your feeding station; it removes a food source hummingbirds depend on and can be harmful to them directly. Maryland wildlife officials specifically warn that hummingbirds can accumulate pesticides in their bodies by eating treated insects and plants. Here's how to handle the two most common pest problems without it.

Ants

Ants are drawn to any spilled or leaking nectar, and once a trail forms, they'll march straight up the feeder pole or hanging hook to reach the source. A vinegar-water spray works well as a deterrent — mist it around (not directly on) the feeder ports, and wipe down the hook or pole where ants tend to travel. A leak-proof feeder design also does real work here: with nothing dripping down in the first place, there's less to draw them in to begin with.

Bees and Wasps

Bees and wasps are trickier than ants, since they're after the same nectar hummingbirds are drinking, not just what's spilled. A vinegar-water spray around the ports can help, but the more reliable fix is a feeder design that keeps them out entirely rather than just discouraging them.

Plant a Maryland Native Hummingbird Garden

Feeders are a wonderful supplement, but nothing beats real, native nectar. Native plants evolved right alongside Maryland's hummingbirds, so they bloom on the right schedule and produce exactly the nectar these birds are looking for.

Best native nectar plants for Maryland:

• Eastern red columbine — one of the earliest bloomers, timed almost exactly to Ruby-throated arrival
• Cardinal flower — brilliant red spikes in late summer, right when hummingbirds need fuel most for migration
• Coral honeysuckle and trumpet creeper — long-blooming tubular flowers built for hummingbird bills
• Bee balm — a reliable midsummer nectar source
• Jewelweed — a shade-tolerant native found along streamsides, also attractive to hummingbirds

Pop's tip: Maryland Department of Natural Resources notes hummingbirds are strongly attracted to red and orange coloring, so plant in groups of the same species or color for maximum visibility — a single scattered plant is much easier for a hummingbird to miss than a solid patch of the same bloom.

If You're Near the Border

Hummingbirds don't check a map before deciding where to feed, so if you're near a state line, your best guide might be a blend of both.

Near Delaware: Nearly identical Mid-Atlantic timing and native plant list. See our Delaware guide for more.

Near Pennsylvania: Shared timing and the full native five confirmed in both. See our Pennsylvania guide for more.

Near West Virginia: Western Maryland's mountain climate shares more with West Virginia's Appalachian pattern than the Chesapeake side does. See our West Virginia guide for more.

To make this easy, our Perfect Little Sanctuary® Wildflower Seed Blend is designed to bring nectar-rich color into your yard with minimal fuss.

When to Plant the Perfect Little Sanctuary® Blend in Maryland

Fall is the best planting window across Maryland — aim for October through November. This timing is based on the germination needs of the blend's own 12 varieties: 9 of the 12 either need or benefit from a cold, moist stratification period before they'll germinate well, including Purple Coneflower, Black-Eyed Susan, Perennial Lupine, and Lance-Leaved Coreopsis, and Maryland's winter cold does that work naturally. Early spring is a solid backup window if you miss fall.

Top Performers in Maryland

The Perfect Little Sanctuary® blend contains 12 varieties, and Maryland's confirmed native ranges point to a strong, mostly-native lineup:

• Purple Coneflower (Echinacea purpurea) — native and a long summer-to-fall bloomer
• Black-Eyed Susan (Rudbeckia hirta) — native, reliable and low-maintenance
• Lance-Leaved Coreopsis (Coreopsis lanceolata) — native, drought tolerant once established
• White Yarrow (Achillea millefolium) — native, extremely low-maintenance once established
• Perennial Lupine (Lupinus perennis) — confirmed native to Maryland in official USDA distribution records
• Painted Daisy (Chrysanthemum carinatum) — not a Maryland native, but a dependable, heat-tolerant annual bloomer that rounds out the bloom season

Pop's tip: You don't need to do anything special to favor these — just sow the blend as directed. The rest of the mix still adds seasonal color, but these varieties are the ones that will do the heaviest lifting in a Maryland yard.

Give Them a Place to Rest

Hummingbirds spend a surprising amount of their day perched, not flying — watching their territory, digesting, and simply resting between feedings. A Pop's Original Hummingbird Swing hung near your feeder gives them exactly that spot, and it turns your feeding station into a front-row seat for watching them up close. Hang it about 1 foot from your feeder, at the same height (Pop's rule of thumb) — see our guide on where to hang your swing for placement tips — and don't be surprised if a hummingbird claims it as their own personal lookout post.

Keep Your Sanctuary Safe from Predators

A feeding station draws more than hummingbirds, and knowing what's actually worth worrying about — and what isn't — makes for a safer yard. Cats and window strikes are the two best-documented threats to hummingbirds around any home. See our full Hummingbird Predators guide for the complete picture.

Summary: Key Takeaways for Attracting Hummingbirds in Maryland

Building a hummingbird-friendly yard doesn't take a green thumb or a big budget — just a little consistency and the right setup. Here's everything from this guide in one place:

• Ruby-throated Hummingbird is Maryland's only breeding species, and its population has grown steadily since 1966 — a genuine conservation bright spot
• Rufous Hummingbird is a real, non-review fall-and-winter visitor, most reliable around Bethesda; five more species — Black-chinned, Calliope, Allen's, Anna's, and Mexican Violetear — are accepted rarities
• Feeder timing: up by mid-April in Calvert County and Southern Maryland, late April elsewhere
• Any size space works — one feeder is plenty for a balcony; larger yards can support multiple feeders spaced apart, since hummingbirds are territorial
• Use a leak-proof feeder with a comfort perch, like the AspenPerch®, and fill it only as full as it'll be drunk in a few days
• Skip red dye in nectar; a plain 4:1 sugar-water ratio or Pop's Nectar (with electrolytes and calcium) both work
• Change nectar every 1–2 days above 90°F, up to every 5–6 days below 70°F, and clean feeders at least twice a week in summer
• Clean the feeder at every nectar change with warm water and vinegar — no soap or bleach
• Never use insecticide near feeders; hummingbirds rely on insects for protein and can accumulate pesticides from treated insects. Use vinegar-water spray and HummGuard® nectar tips for pest control instead
• Add a swing near the feeder to give hummingbirds a place to rest and be observed up close
• Cats and window strikes are the two best-documented threats to hummingbirds around any home
• Native, nectar-rich plants (eastern red columbine, cardinal flower, coral honeysuckle, bee balm) do more for hummingbirds long-term than feeders alone
• Sow wildflower seed in October–November for blooms timed to spring migration; Purple Coneflower, Black-Eyed Susan, Lance-Leaved Coreopsis, White Yarrow, and Perennial Lupine are the strongest Maryland performers in Pop's Perfect Little Sanctuary® blend

Get these basics in place, and the wonder takes care of itself.

Frequently Asked Questions

A few of the questions we hear most from fellow hummingbird lovers across Maryland:

When should I put my hummingbird feeder out in Maryland?

Mid-April is a safe target for Calvert County and Southern Maryland; late April works for the rest of the state, since males typically begin arriving and establishing territory around that time.

Do hummingbirds stay in Maryland year-round?

Almost never as a rule, but some individuals too old or unwell to migrate will overwinter locally, and Rufous Hummingbird is a genuine, non-review fall-and-winter visitor, most often reported around Bethesda. Ruby-throated Hummingbirds, Maryland's only breeding species, typically migrate south each fall.

Is it bad to leave my feeder up in fall?

Not at all — it's a myth that a feeder left up will delay migration. Hummingbirds migrate based on daylight and instinct, not food availability, and a full feeder just helps them refuel for the journey ahead, or gives a wintering Rufous a reason to stick around.

How often should I clean my hummingbird feeder in Maryland?

At least twice a week in summer, using warm water and a mild vinegar solution — Maryland wildlife officials specifically warn that mold and bacteria buildup in feeders can be deadly to hummingbirds.

What are the best plants to attract hummingbirds in Maryland?

Eastern red columbine, cardinal flower, and coral honeysuckle perform well across the entire state, with bee balm and jewelweed as strong supporting choices. Native, tubular, red or orange flowers are the general rule of thumb.

A Notable Maryland Connection

Every hummingbird band placed anywhere in the United States traces back to Maryland: the National Bird Banding Laboratory, operated by the U.S. Geological Survey, is located in Laurel, MD, and supplies the aluminum bands and tracking database used by every licensed bander nationwide, including all of Pop's Birding's own state guides mentioning banded hummingbirds. It's a federal research facility, not a visitor site, but it's a genuinely interesting behind-the-scenes fact for our Maryland birders.

Why We Built This Guide

Pop's Birding has been helping hummingbird lovers for three generations. One of the questions our customers ask most often is "How do I actually attract more hummingbirds to my yard?" — we built this guide to give a direct, practical answer, not a generic one. Most hummingbird content defaults to alarm about declining populations, but Maryland's own data tells a different story: Ruby-throated Hummingbird numbers here climbed steadily from 1966 all the way to 2014, a genuine conservation bright spot most guides never mention. We also found that Calvert County isn't just the earliest-arriving, latest-departing corner of the state — it's the same county producing Maryland's most reliable Black-chinned Hummingbird records, a real pattern generic statewide advice would miss entirely. We wanted a guide that gets Maryland's actual regional picture right, not one that treats the whole state as a single average.

How We Built This Guide

The regional arrival and departure windows on this page come from our own analysis of eBird checklist data (Cornell Lab of Ornithology) for Maryland statewide and four representative counties — Montgomery, Calvert, Worcester, and Garrett — 2016 through 2025. The accepted species list and each rarity's review status are checked against the Maryland/DC Records Committee's own official bird list rather than assumed, and the feeder-cleaning frequency, the yellow-feeder-part warning, and the pesticide-accumulation note all come directly from Maryland Department of Natural Resources guidance rather than generic national advice. Perennial Lupine's native status was checked against official USDA distribution records rather than carried over from a similar state's blend, and each neighboring-state comparison reflects that state's own real climate and plant overlap rather than an assumption that Maryland's list simply continues across the line.
