Things That Go Bump—or Hoot—in the Night: 5 Animals You May Hear While Camping in Your Yard

Welcome to June, officially designated as Great Outdoors Month by the federal government and several states across the country. Here at the National Wildlife Federation, we’ll be celebrating the outdoors in a big way on with NWF’s Great American Campout.

If you participate–and we hope you do–here’s an idea for something to do in the dark without your television or computer handy. Just sit quietly and listen! Depending on where you live, you’re likely to hear one or more of the following animals vocalizing sometime between sunset and sunrise.

1. Owls

North American owls range in size from the tiny elf owl—at 5¾ inches, the world’s smallest owl species—to the great horned owl, a powerful predator that is nearly 2 feet long. Ecologically, owls are similar to hawks but hunt at night rather than during the day. Both owls and hawks have plumage that is primarily brown, rust, black and white. Differences stem from owls’ nocturnal hunting. The birds have round facial discs, for instance, that focus sound waves to highly sensitive ear openings. And owls’ eyes are specially adapted to gather what little light may be available at night.

Listen to the “Who cooks for you, who cooks for you all?” call of the barred owl:

2. Katydids

Closely related to grasshoppers and crickets, katydids sing at night during the warm months throughout much of North America. Males do the singing in order to attract mates and establish territories. Their songs are produced by rubbing a set of tiny pegs, called a file, at the base of one wing against a strong ridge, called a scraper, on the other wing. Each katydid species has its own unique song, which both males and females can hear with ears that are located on the insects’ forelegs.

3. Frogs

Scientists have described nearly 6,000 frog species, and these amphibians live pretty much everywhere on Earth except in Antarctica. The United States and Canada are home to about 100 species. Spring is the time to start listening for frogs such as spring peepers and wood frogs. Other species wait until the weather warms. Frog calls also are slower at low temperatures because muscles that make the sounds move more slowly. Frogs around the world are in trouble: About 120 species have gone extinct in recent years, and one-third to one-half of the others are a risk.

4. Crickets

Nothing evokes a warm summer night quite like the soothing sound of crickets chirping. Like katydids, male crickets sing to attract mates and create their species-specific songs by rubbing their wings together. At 77 degrees F, field crickets chirp about two or three times per second, slowing down when the temperature drops. Crickets, katydids and grasshoppers all belong to insect order Orthoptera, which includes some 21,400 known species worldwide, about 1,200 of them found in North America north of Mexico.

5. Mockingbirds

During the breeding season, many songbirds begin their dawn chorus well before sleepy campers crawl out of their tents. But if you hear a bird singing loudly (perhaps annoyingly) in the middle of the night, it’s likely to be the northern mockingbird. Skilled mimics, mockingbirds put together long, complex songs by combining imitations of other bird species (and sometimes non-avian sounds). The birds continue adding new sounds to their repertoires as long as they live. Males, which sing more often and louder than females, may learn some 200 different songs during their lives.
