What Animal Makes This Noise? Sounds in Attic, Yard, Woods

To work out what animal is making a noise, start with where it is (inside the house, in the yard, in the woods), the time of night, and the type of sound (scratching, thumping, screaming, hooting, whinnying, chirping). Those three facts narrow the list more than trying to imitate the sound. The sections below group the common culprits that way, using descriptions from The Nature Conservancy, the Audubon field guide, Critter Control, Catch It Wildlife Removal in Illinois and Wikipedia's list of animal sounds.

• Faint, quick scratching in walls, floors or the attic after dusk: mice or rats (Catch It). Critter Control lists high-pitched squeaking for both.
• Loud scratching and heavier, abrupt thumps in the attic in the early night or at dawn: squirrels (Catch It). Critter Control also lists chirping and high-pitched squeaks.
• High-pitched chirps, squeaks or clicking in the attic or walls in warm months: bats (Catch It; Critter Control).
• Chirping in the chimney: Critter Control lists chimney swifts.
• Squeaking or chattering from a large animal in the attic: raccoons, which Critter Control credits with over 200 vocalizations; babies give high-pitched squeaks.
• Repeated drumming on eaves, gutters or siding: woodpeckers (Catch It).

Rodents and bats leave droppings, which confirm the culprit: see rat scat identification and the animal poop identification chart. Do not try to catch or handle a wild animal in the house; contact a licensed wildlife control operator or your state wildlife agency.

Screams are the noise people most often ask about, and The Nature Conservancy's list of nighttime noises covers the usual sources:

• Red fox: the vixen's scream. Catch It describes it as high-pitched and similar to a person calling out in distress; Critter Control likens it to a screaming woman. Wikipedia's list of fox sounds also includes barks, howls, yips and the gecker.
• Barn Owl: a rasping, harsh scream, given by males in flight, rather than a hoot.
• Raccoon: a shriek likened to a high-pitched pig squeal, with grunting and screams during fights.
• Bobcat: loud yowls and screams (Critter Control).
• Coyote: howls, yips and barks, heard most from January to March when they mate; Catch It notes they can sound eerily like laughter.
• Peafowl and feral pigs where they occur: peafowl give a honk and a high-pitched repeating scream; feral pigs squeal, grunt and growl in groups.

• Barred Owl: a loud, barking series, which Audubon writes as hoo, hoo, hoo-hoo; hoo, hoo; hoo, hooo-aw!, plus other barking calls and screams. Pairs often call back and forth.
• Great Horned Owl: the classic deep hoo hoo hoot of wooded areas (Catch It).
• Eastern Screech-Owl: despite the name, it does not screech. Audubon describes a tremulous, descending wail and soft purrs and trills; Catch It compares the whinny to a horse.

A whinny in the yard at night is far more likely a small owl than a horse, and a scream is more likely a fox or a Barn Owl than a screech-owl.

• Rhythmic rustling with clanking or scraping: raccoons in the garbage (Catch It). Wikipedia lists the raccoon's call as a trill.
• Shuffling and snuffling near compost or in dry leaves: opossums (Catch It); Critter Control and Wikipedia add clicking, growls and hisses.
• Hissing or snorting: skunks (Catch It).
• Heavy footfalls with twigs cracking: deer, more active at night in the mating season (Catch It). Wikipedia lists a buck's bellow and a doe's or fawn's bleat.
• Croaks, ribbits and chirps near water: frogs; steady chirping from grass: crickets (Wikipedia's list of animal sounds).

For birds, yes. Cornell Lab's free Merlin Bird ID has Sound ID, which its help center says identifies 2000+ species, covering most birds of the US, Canada and Europe. Its help center does not describe identifying frogs, insects or mammals.

For other animals, the options are thinner. iNaturalist lets you upload a sound recording from its website or Android app, but a thread on the iNaturalist forum confirms it has no automatic suggestions for sounds: the community identifies recordings by ear. Google Lens is an image tool (Wikipedia), so it helps only if you can photograph the animal.

NatureLens also works from photos. If you can photograph the animal, or the tracks and droppings it leaves, the app can suggest what it is, with free scans every day; see our animal track identification guide.

• Record with your phone's voice recorder or the Merlin app, which the iNaturalist forum notes saves recordings as .wav files. Point the phone toward the sound and stay still.
• Say the time, place and what you are hearing at the start of the clip, or write it down straight after.
• Note where the sound was coming from: inside a wall, the attic, the roof, the yard, the trees, water.
• If you post to iNaturalist, upload the audio file itself. Forum members ask people not to upload spectrogram images as the evidence photo, because it makes a confusing dataset; put a spectrogram in a comment instead.
• Look the next morning for tracks, droppings, chewed material or disturbed trash, which often identify the animal more reliably than the sound.
