The hummingbirds of Pennsylvania
Ruby-throated Hummingbird
Archilochus colubris
Summer nester in Pennsylvania.
How to recognize it: Emerald back; adult male's throat flashes ruby red and looks black in shade; forked dark tail on males.
The only hummingbird that nests regularly east of the Great Plains. Many cross the Gulf of Mexico nonstop in spring, a flight of about 500 miles.
When to put out hummingbird feeders in Pennsylvania
Scouts reach Pennsylvania around April 25, a little earlier in the south of the state and later at elevation. Males travel ahead of females by a week or more and arrive before many native flowers open, so a feeder hung two weeks early, by April 11, gets used. Across 135 Pennsylvania cities in the NOAA 1991–2020 normals, the typical last spring freeze falls around April 30, after the first hummingbirds arrive. Expect a few frosty nights with birds already here; bring feeders in if they freeze and rehang them at first light.
When to take hummingbird feeders down in Pennsylvania
Leaving feeders up does not keep hummingbirds from migrating; day length triggers departure. Adults leave first, then juveniles, and late stragglers from farther north pass through after your own birds have gone. In Pennsylvania most have left by October 5. Keep at least one feeder clean and filled until October 19, two weeks after the last bird you see.
Native flowers for hummingbirds in Pennsylvania
Feeders bring hummingbirds in; flowers and the insects on them keep them nesting nearby. These natives grow in Pennsylvania (USDA 5a–7b):
- Cardinal flower (Lobelia cardinalis): Late-summer red spikes for moist soil.
- Trumpet honeysuckle (Lonicera sempervirens): Native red tubular flowers timed to hummingbird arrival.
- Trumpet creeper (Campsis radicans): Large orange trumpets through midsummer.
- Wild bergamot (Monarda fistulosa): Tubular flowers for hummingbirds and seed heads for finches.
- Fireweed (Chamaenerion angustifolium): Tall magenta spikes are a key northern hummingbird flower.
Nectar and cleaning
- Mix 1 cup plain white sugar into 4 cups water; boiling is optional if you use clean water and change it on schedule.
- No red dye, honey, brown sugar or sweeteners. A red feeder is enough to attract them.
- Change nectar every 2 days above 80°F, every 4–5 days in cooler weather; cloudy nectar has fermented.
- Scrub ports with a bottle brush at each change; soak monthly in 1 part vinegar to 4 parts water.
- Use an ant moat and keep feeders out of full afternoon sun to slow spoilage.
Frequently asked
What hummingbirds live in Pennsylvania?
Pennsylvania has one regular hummingbird, the Ruby-throated Hummingbird (summer nester).
When should I put out hummingbird feeders in Pennsylvania?
Hang feeders by about April 11. The first hummingbirds usually reach Pennsylvania around April 25, and early birds find little in bloom.
When should I take hummingbird feeders down in Pennsylvania?
Most leave by about October 5. Keep feeders up until October 19, two weeks after the last one you see; a feeder does not stop birds from migrating.
Can hummingbirds handle a late frost in Pennsylvania?
The typical last spring freeze across Pennsylvania cities is around April 30. Hummingbirds survive cold nights by dropping into torpor, but nectar feeders matter most when flowers are frosted. Bring a feeder in overnight if it freezes solid and rehang it at dawn.
What is the right sugar water ratio?
One part plain white sugar to four parts water, no red dye, no honey. Change it every two days when highs are above 80°F and every four to five days in cooler weather.

Hummingbird feeders and ant moats
Feeders and add-ons that suit the nectar schedule above.
Hanging Basin Feeder and Water Bowl
A single open basin that hangs from a hook and does two jobs: a seed tray through the growing season, a shallow water bowl the rest of the year. Seed or water goes straight in — no reservoir, no perches, nothing to assemble beyond the hanging chains.Three chains run from the rim to one S-hook, so the basin hangs level under a bracket, a shepherd's hook or a low branch. Put it where you can watch it from a window, and where a cat can't launch from a fence.The rim is low and the floor is open, so birds can land anywhere around the edge instead of fighting over a perch. It also means the bowl needs wiping out every few days: hulls and droppings land in the water, and a rinse with hot water and a brush keeps it clean.The basin has a wood-grain finish and hangs from black metal chains.
Round Suet Ball Cage
A small round wire cage made to hold one suet or fat ball. The hinged cage opens for refilling and closes with a simple wire latch. A short chain and hook are included for hanging. Available in gold-colored or black finish. This is a suet holder, not a hummingbird feeder.
Five-Port Hummingbird Feeder
A compact red hummingbird feeder with a clear 8-ounce reservoir, five flower-shaped feeding ports, and five curved perches. The set includes a separate ant-moat cup and an S-hook for hanging. The wide base separates for routine washing. Use plain white sugar nectar at a 1:4 sugar-to-water ratio; never add dye.
Hummingbird Ant Moat Hooks, 4-Pack
Four red metal S-hooks, each with a built-in water cup. Hang the hook from your bracket, hang the feeder below it, and fill the cup with water. Ants walking down toward the nectar hit the water and stop.Specs Material: metal with red coating Pack: 4 moat hooks + 4 small cleaning brushes Fits most hanging feeders with a wire or loop hanger Use Plain water only. Never add oil or insecticide to the cup. Top up every few days in hot weather; a dry moat does nothing.
