You’re sitting on your back porch in Cherry Hill or maybe hiking a trail up in High Point, and something flash-bulb bright streaks through the oak trees. It’s red. Not just "reddish," but that deep, velvety crimson that stops you mid-sentence. Most people immediately shout "Cardinal!" and go back to their coffee.
They’re usually right. But honestly? Not always.
New Jersey is a weird, wonderful bottleneck for avian migration, and if you think the Northern Cardinal is the only red bird in New Jersey worth talking about, you’re missing out on some of the coolest wildlife spectacles in the Northeast. From the "lipstick red" Summer Tanagers that sneak into South Jersey to the chunky, social grosbeaks that only show up when the Canadian winters get too brutal, the Garden State is a scarlet-hued treasure hunt.
The Cardinal is King (But He’s Also Kind of a Homebody)
Let’s get the obvious one out of the way. The Northern Cardinal (Cardinalis cardinalis) is the year-round heavyweight champion. Unlike a lot of birds that pack up and head for Florida the second the temperature hits 50 degrees, cardinals stick it out.
They’re tough.
You’ve probably noticed they’re the first ones at the feeder in the morning and the last ones to leave at dusk. There’s a biological reason for that—they’ve evolved to feed in low light to avoid some of the daytime predators. In the winter, that red feathers-against-white-snow contrast is basically the unofficial mascot of a Jersey January. But here’s the thing: only the males are red. The females are a sophisticated, warm tan with just enough red in the wings and tail to let you know they’re related.
If you want more of them in your yard, stop buying the cheap "grocery store" birdseed. It's mostly filler. Cardinals have those massive, cone-shaped beaks designed for one thing: cracking. They want black oil sunflower seeds or safflower. If you provide that, they’ll basically move in and become your new roommates.
The Summer Tanager: South Jersey’s Secret
While everyone knows the cardinal, very few people realize that New Jersey is the northern frontier for the Summer Tanager. These birds are a different kind of red—a solid, bee-stung rose-red without the black mask of a cardinal.
They’re picky.
You won’t find them in a suburban cul-de-sac in Paramus. If you want to see a Summer Tanager, you have to head south. The Pine Barrens are their stronghold. Places like Belleplain State Forest in Cape May County or the sandy oak-pine forests of Ocean County are where they hang out.

What’s fascinating about these guys is their diet. They’re "bee and wasp specialists." They will sit on a branch, wait for a wasp to fly by, snatch it out of the air, and then bash it against a branch to remove the stinger before eating it. It’s brutal and impressive. Because they stay high in the canopy, they’re often heard before they’re seen. Listen for a "pit-i-tuck" call that sounds like someone clicking their tongue.
The Scarlet Tanager: The Tropical Ghost of the North
If the Summer Tanager owns the south, the Scarlet Tanager owns the north. This is, hands down, the most vibrant red bird in New Jersey. They look like they were dipped in neon paint.
Wait.
Actually, they look like a piece of coal that’s still glowing red, because their wings and tails are jet black. It’s a striking contrast that feels like it belongs in the Amazon rainforest. Which, to be fair, is where they spend their winters.
They arrive in Jersey around early May. If you’re hiking in the Delaware Water Gap or the Highlands, look up. They love mature deciduous forests—big oaks, big maples. The weird part? Despite being bright red, they are incredibly hard to see. They like to hide in the thickest clusters of leaves at the very top of the trees.
One thing that trips people up is the "molt." By late summer, the males start losing those red feathers and turn a patchy, splotchy yellow-green. By the time they fly back to South America, they look like entirely different birds. If you see a "red bird" in October, it’s almost certainly not a Scarlet Tanager.
The Winter Weirdos: Pine Grosbeaks and Crossbills
Every few years, something called an "irruption" happens. It’s not a volcano; it’s a food shortage. Up in the boreal forests of Canada, if the cone crops or fruit crops fail, the birds that live there head south in a desperate search for snacks.
This is when New Jersey gets lucky.
The Pine Grosbeak is a chunky, slow-moving bird that looks like a cardinal on steroids but without the crest. They’re incredibly tame. You can sometimes walk right up to them while they’re munching on crabapples in a suburban park. They don't see humans as a threat because they spend their lives in the remote wilderness where humans don't exist.
Then there are the Crossbills. Their beaks actually overlap at the tips—hence the name. It looks like a birth defect, but it’s a specialized tool for prying open pine cones. Seeing a flock of Red Crossbills at a place like Sandy Hook or the Manasquan Reservoir is a birdwatcher's equivalent of winning the lottery.
Purple Finches vs. House Finches: The Great Confusion
This is where the most common mistake happens. Someone sees a small, streaky bird with a red head and says, "Oh, a Purple Finch!"

Probability says no.
In most Jersey backyards, what you’re seeing is a House Finch. They’re everywhere. The males have a red brow, throat, and rump, but their bellies are streaked with brown. They were actually introduced from the Western U.S. in the 1940s (long story involving a pet shop in Long Island) and they’ve taken over.
The real Purple Finch is a bit of a misnomer. They aren’t purple. They look like they were dunked head-first into a bowl of raspberry jam. The red covers more of their body and it’s a deeper, richer "wine" color. They’re mostly winter visitors in New Jersey. If you’re trying to tell them apart, look at the bird’s side. If there are heavy brown streaks on the belly, it’s a House Finch. If it looks like it’s blushing everywhere, you’ve got a Purple Finch.
Why Red Birds Matter to the Jersey Ecosystem
Color isn’t just for show. In the bird world, red is often a signal of health. Most of these birds get their red pigment from carotenoids in their diet—specifically from berries and insects. A bright red male cardinal is telling every female in the neighborhood, "I am great at finding food and I have a killer immune system."
When we lose native plants like Spicebush, Serviceberry, and Virginia Creeper, we lose the fuel these birds need to stay vibrant. Suburban lawns are basically deserts for red birds. If you want to actually see these species, you have to protect the pockets of wildness left in the state.
Practical Steps for Finding Red Birds in New Jersey
If you’re serious about spotting these birds, you can't just wander around and hope for the best. You need a strategy.
- Check the "Hotspots": Use eBird. It’s a real-time database where birders log sightings. If a flock of Evening Grosbeaks or a rare Summer Tanager pops up at Cape May Point, you’ll know within an hour.
- Timing is Everything: Mid-May is the "sweet spot" for tanagers. They are fresh off migration and singing their heads off to establish territory.
- Plant Native: If you have even a tiny patch of dirt, plant a Highbush Blueberry. It’s native to NJ, the birds love the fruit, and the bushes themselves turn a beautiful red in the fall.
- Listen First: Learn the "cheer-cheer-cheer" of the cardinal versus the "robin with a sore throat" song of the Scarlet Tanager. Most of the time, your ears will find the bird before your eyes do.
New Jersey gets a bad rap for being all turnpikes and malls. But when you’re standing in the middle of the Pine Barrens and a Summer Tanager drops down to a branch right in front of you, the rest of the world kind of fades out. It’s just you and this impossibly bright, living jewel in the middle of the woods.
Next Steps for Birding in NJ
Start by upgrading your gear. A decent pair of 8x42 binoculars will change your life—you'll see the individual feathers and the light in their eyes, not just a red blur. Next, download the Merlin Bird ID app from the Cornell Lab of Ornithology. It has a "Sound ID" feature that works like Shazam for birds; you just hold your phone up, and it tells you exactly who is singing in the trees above you. Finally, take a Saturday morning trip to the Garrett Mountain Reservation or the Cape May Bird Observatory. These are world-class locations where experts are usually hanging around and more than happy to point out a rare bird to a beginner.
