Unfortunately, hummingbirds don’t live in New Jersey year-round. 🙁

At the end of every summer, Ruby-throated Hummingbirds (the only common species in the state) depart New Jersey to migrate south to southern Mexico and Central America. They spend the winter here in the warm weather before coming back next spring!

So when exactly do hummingbirds leave New Jersey?

Ruby-throated Hummingbirds start their southward migration once their breeding season ends. It’s believed that they can sense the changes in the reduced number of daylight hours, flowers, and insects, which triggers their instinct to leave New Jersey.

This means that most hummingbirds leave New Jersey by the end of August or early September. By mid-September, almost all birds are gone, and they won’t return again until spring.

But keep your eyes open for any hummingbirds that started their migration late. It’s not uncommon to see a straggler passing through New Jersey towards the end of September, especially if they started their migration from much higher north!

I’m guessing that the reason you wanted to know when hummingbirds leave New Jersey is that you were curious when you can put away your feeders for the winter?

Here’s what I always recommend:

Don’t take down your feeders until you haven’t seen a hummingbird for TWO weeks.

Once that happens, you can be very confident that almost all the hummingbirds in New Jersey have left for the year!

Trust me; you definitely don’t want to take away the nectar in your yard too early. Hummingbirds migrate a LONG way and need lots of ENERGY, which you can hopefully provide to them.

When do you normally see the last hummingbirds leave New Jersey?

  1. I live in Paramus, N.J. (NW of GWB).
    It is currently 11/30/2024- it was below freezing overnight (fountain and bird baths frozen. 30 degrees F @ 8am. 37 degrees F @10:30 am.
    A female hummingbird (presumed Ruby Throated) has been clearly observed here since 11/20/2024 frequenting a sunny hedge of spirea and forsythia and does not appear distressed. It seemed most attracted to zinnias which were still in bloom and ‘Mexican hats’ still in bloom. I put back up my feeder and the bird gradually accepted it but was clearly independent of it. I expected the bird to stay a day or two and move on. It rejected a small 3-sided shelter I made (perhaps due to causing blind spots for the bird) so I removed it. The bird is still here. I’m amazed. Is this beyond unusual?
