Listening at the Edges: Crepuscular Birding in Summer

-It is common for birders to head out early. We chase the morning chorus because we know that’s when most birds are active—singing, defending territories, feeding young.

But there’s another time I’ve come to love just as much. As the sun drops and the light starts to fade, a different group of birds takes over. The prairie quiets, the wind settles, and species tuned to twilight begin to stir. These are crepuscular birds—those that thrive in the soft hours between day and night.

Why Twilight Works

Crepuscular species aren’t just night-owls-in-training. They’ve evolved to take advantage of what the twilight of dawn and dusk offers. Insects are everywhere—emerging in clouds over fields and wetlands. Temperatures cool. Raptors settle down. Competition thins out.

For birds like Common Nighthawks, Common Poorwills, and Short-eared Owls, this window isn’t a compromise—it’s prime time.

Out in the field, I’ve seen nighthawks begin to rise and poorwills start to call the moment the sun slips behind the ridge. These transitions aren’t just interesting—they’re timed. Purposeful. You start to notice how tightly these birds are tuned to the light itself.

Some Familiar Faces in Low Light

Here are a few of the birds I look forward to encountering every June as day slips toward dusk:

  • Common Nighthawk – You’ll usually hear them before you see them. That sharp “peent” call overhead, followed by the deep boom of wind through their wingtips as they dive—always stops me mid-step.
  • Common Poorwill – One of the few North American birds known to enter torpor (a hibernation-like state) the Poorwill’s low, repetitive call blends into rocky canyons and arid hillsides of the West. These birds perch on the ground, nearly invisible, then launch out to snag moths in the low light.
  • Short-eared Owl – An awe-inspiring twilight bird. I’ve seen them reinforce their pair bonds at dusk, projecting their barking call and clapping their wings as they float like oversized moths over the prairie.
  • American Woodcock – Best known for their dramatic spring sky dance, woodcock are strongly crepuscular. Males perform display flights at dawn and dusk, and both sexes forage for earthworms in damp fields during twilight hours.
  • Black-crowned Night-Heron – Often hidden during the day, night-herons are solid crepuscular hunters. I regularly hear them croak as they fly over in search of wetlands and prey.

Twilight birding slows everything down. You stop scanning and start listening. You pick up on subtleties—the bark of a Short-eared Owl out over the prairie, the first sharp “peent” of a nighthawk overhead, the hush that settles just before a night-heron moves.

I’ve learned not to rush this part of the day. The birds don’t appear all at once. They filter in with the light, one call or shadow at a time. You have to let your senses adjust—and give the moment space. That’s when it happens.

The world doesn’t go quiet at dusk. It just shifts to a different frequency.

Listening Beyond the Checklist

It’s easy to slip into list-making mode—counting, tallying, chasing targets. But twilight birding invites something different. It asks you to wait. To notice. To be still long enough for something unexpected to show up.

Some birds reveal themselves only when the pressure is off. And often, those are the moments that deepen your connection to place—not because you were trying to find something, but because you didn’t leave.

Join Me in Veracruz

If you’re looking for your next birding adventure, I’ll be co-leading a tour this fall to Veracruz, Mexico, during the peak of the River of Raptors migration—the largest raptor migration in the world.

From hawk-watching on hotel rooftops to searching for endemics in mountain forests, this trip offers incredible bird diversity, expert local guides, and time to connect with the landscape in a meaningful way. You’ll also be supporting the vital work of the Pronatura Veracruz monitoring program.
