The hummingbirds of New Jersey

Ruby-throated Hummingbird

Ruby-throated Hummingbird

Archilochus colubris

Summer nester in New Jersey.

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 New Jersey

Scouts reach New Jersey around April 20, 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 6, gets used. Across 73 New Jersey cities in the NOAA 1991–2020 normals, the typical last spring freeze falls around April 17, so most birds arrive after the frosts are over.

When to take hummingbird feeders down in New Jersey

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 New Jersey 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 New Jersey

Feeders bring hummingbirds in; flowers and the insects on them keep them nesting nearby. These natives grow in New Jersey (USDA 6a–7b):

  • Trumpet honeysuckle (Lonicera sempervirens): Native red tubular flowers timed to hummingbird arrival.
  • Trumpet creeper (Campsis radicans): Large orange trumpets through midsummer.
  • Cardinal flower (Lobelia cardinalis): Scarlet late-summer spikes; a hummingbird magnet in moist soil.
  • 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 New Jersey?

New Jersey has one regular hummingbird, the Ruby-throated Hummingbird (summer nester).

When should I put out hummingbird feeders in New Jersey?

Hang feeders by about April 6. The first hummingbirds usually reach New Jersey around April 20, and early birds find little in bloom.

When should I take hummingbird feeders down in New Jersey?

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 New Jersey?

The typical last spring freeze across New Jersey cities is around April 17. 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.
