Night Birds In Pennsylvania
1. Northern Mockingbird
- Scientific name: Mimus polyglottos
Northern mockingbirds are birds most often heard singing during the night in Pennsylvania. The nighttime singers are often young, unattached males or older males without mates.
They are most noisy from March to August (their breeding season) and from late September to November (while establishing winter territories).
To reduce their constantly annoying singing, consider using bird nets on trees or placing cardboard cutouts of predators like hawks or owls.
These birds are year-round residents in PA and are aptly named, as they can mimic over 200 different songs and imitate up to 35 species.
Their mimicry extends to sounds like rusty hinges, car alarms, cackling hens, and dog barks, sometimes indistinguishable even with electronic analysis.

2. Yellow-breasted Chat
- Scientific Name: Icteria virens
Yellow-breasted chats can be often heard singing in the morning and evening during summer in Pennsylvania. They will also even sing at night during the height of their breeding season (May to July).
Often heard than seen, they are common around dense, brushy areas and hedgerows. These birds have a unique mix of cackles, clucks, whistles, and hoots in their songs, along with harsh “chak” calls.

They can mimic other birds, sometimes confusing birdwatchers. During the breeding season, they become more conspicuous, singing from exposed spots and flying openly while gurgling their songs.
3. American Robin
- Scientific name: Turdus migratorius
American robins are songbirds and common sights in forests, lawns, and suburbs across PA, throughout the entire year.
As winter fades and daylight increases, they will be the first birds you hear singing just as dawn approaches, giving them the nickname “wake robins.”
The song is described as a “cheery” carol consisting of a string of 10 or so clear whistles; American robins also have a sharp “yeep” alarm call or a mumbled “tuk” when communicating with one another.

4. Killdeer
- Scientific Name: Charadrius vociferus
Killdeers can be found year-round in most of the state. They inhabit open areas like sandbars, mudflats, fields, and even urban locations.
They’re recognized by their brown plumage with two black breast bands, orange tails, pink legs, and white wing stripes.
Killdeers are active day and night, with noticeable nighttime activity, especially in early spring and late summer. They often congregate in places like mall parking lots and well-lit ball fields, engaging in socializing, calling, and searching for food. Their name comes from their loud, piercing calls resembling “kill-deer, kill-deer.”

5. American Woodcock
- Scientific Name: Scolopax minor
American woodcocks, small elusive birds, can be heard in PA from dusk to dawn. Look for them in fields near forests, especially around powerline cuts.
They’re challenging to spot due to their nocturnal habits and camouflaged colors. Listen for their distinctive “peent” call on the ground or twittering in the air.

6. Wilson’s Snipe
- Scientific Name: Gallinago delicata
Like American woodcocks, Wilson’s snipes are also found in PA. Although mostly prevalent in northern parts of the state, they prefer wet fields, marshes, and bogs, residing there during summer. Look for them at dawn and dusk.
Recognize them by their “tuk-tuk” call from the ground. They have an intriguing winnowing display flight, creating distinct sounds in the air. Males fly high in circles, then dive, producing longer-lasting sounds. You can observe this behavior both day and night.

7. Eastern Screech-Owl
- Scientific Name: Megascops asio
Eastern screech owls are small, stocky, and strictly nocturnal. They live in Pennsylvania’s woodlands near water and lower elevations year-round.
They’re most vocal near sunset, becoming quieter later at night. Calls increase around full moons and before storms. Listen for the “whinny” and trilling tremolo calls. In summer (June-August), watch for juvenile hissing sounds.

Females have higher-pitched calls, peaking after midnight. They may sing in duets in winter or spring and have distinctive juvenile begging calls in summer, sometimes resembling barn owls’ calls.
9. Barn Owl
- Scientific Name: Tyto alba
One of the most widely distributed species of owl in the world, barn owls are permanent residents of PA.
These medium-sized owls often have a “ghostly” appearance, especially if seen at night, around open habitats, including grasslands, marshes, and agricultural areas.
Barn owls do not hoot and make bone-chilling screams instead. They hunt for rodents during the night and roost in nest boxes, caves, tree hollows, and old buildings.

They are quite common in the USA and are among many birds seen and heard during the night in Florida.
10. Barred Owl
- Scientific Name: Strix varia
Barred owls are year-round Pennsylvania residents, found in dense forests near water. They’re active at night, known for their “who-cooks-for-you” song and “hoo-ahhh” calls, often in duets.

Juveniles have a unique high-pitched raspy hissing sound. These massive owls have mottled brown and white plumage.
11. Long-eared Owl
- Scientific Name: Asio otus
These elusive birds blend well into open forests, marshy areas, and dense coniferous woods of the state. Long-eared owls can be heard singing at night in Pennsylvania year-round.
Very rare, they come alive shortly after dusk, remaining active throughout the night. These owls are generally quiet but make distinct calls. The male’s song resembles low-pitched “hoo” notes, like blowing across a bottle.

They also have a distinctive juvenile begging call, though be cautious, as it can be confused with distant barking dogs or mooing cows.
12. Short-eared Owl
- Scientific Name: Asio flammeus
Short-eared owls, widely distributed worldwide except in Antarctica and Australia, visit PA during winter. They’re often heard in open grasslands, including fields, marshes, and even airports.
These owls have striking yellow eyes with black rings, resembling mascara. While usually quiet, they produce “voo-hoo-hoo” calls.

13. Northern Saw-whet Owl
- Scientific Name: Aegolius acadicus
Northern saw-whet owls are nonbreeding residents of the state during winter. Some northernmost populations might even stay in PA year-round.
Northern saw-whet owls were named after their loud and repetitive whistles described as “a saw being sharpened on a whetstone”. Their calling peaks around 2 hours after sunset and decreases until just before sunrise.
Listen for the tooting advertising song of males, a repeated “toot-toot-toot.” They give a variety of other calls, and later in the season, juveniles produce a raspy, hissing call.
The compound called porphyrin makes their flight feathers unique – the pigment gives their feathers a neon pink fluorescence when exposed to UV light.
14. Pied-billed Grebe
- Scientific Name: Podilymbus podiceps
Pied-billed grebes, small and stocky water birds, are common in Pennsylvania’s marshes and ponds with emergent vegetation during summer. Active at night, they produce loud, whooping, cuckoo-like songs, often duetting with their mates.
Their brown plumage, darkening on the crown and back, provides effective camouflage, making them a bit challenging to spot.

15. Eastern Whip-poor-will
- Scientific Name: Antrostomus vociferus
Eastern whip-poor-wills visit PA during the breeding season. These cryptic nocturnal birds are heard more often than seen.
They hide during the day, typically in pine barrens and forest openings. At dawn and dusk, they begin singing their famous “whip-poor-will” song.

16. Common Nighthawk
- Scientific Name: Chordeiles minor
During the summer breeding season in Pennsylvania, common nighthawks can be heard singing at dawn and dusk. These medium-sized raptors with deeply forked tails and long wings can be found in prairies, forests, savannahs, and urban areas.
These birds create a distinct peent sound and perform courtship displays with rapid dives that produce a booming sound as air rushes over their wings.

Common nighthawks are well-camouflaged during the day, with gray, black, and brown plumage and white patches near the base of their primary feathers.
17. Common Gallinule
- Scientific Name: Gallinula galeata
Common gallinules are medium-sized marsh birds with dark plumage, white undertails, red frontal plates on their heads, and distinctive long legs and toes.
In the state, they are summer residents and prefer freshwater wetlands with open water and emergent vegetation.
They are most active during dawn and dusk, becoming more vocal from April to June during the breeding season. Listen for their “marsh chicken sound” and single “clucks,” which are their most commonly heard calls.
18. American Coot
- Scientific Name: Fulica americana
American coots are small water birds with black plumage, bright white beaks, red eyes, and yellow-green legs.
Although they resemble ducks, American coots are only distantly related to them. These winter residents of Eastern Pennsylvania can be seen and heard in freshwater wetlands with open water and emergent vegetation around dawn and dusk.
They produce a sharp “poot” call and a screeching “kree” sound, and they are particularly noisy swimmers, so you may also recognize them by splashing water sounds.
19. Virginia Rail
- Scientific Name: Rallus limicola
Virginia rails are compact aquatic birds commonly heard in PA during summer nights. They are found around wetlands with cattails, where they often make harsh “kuk-kuk-kuk” calls; their “grunt” calls can be used for communication between mates.
They are often found together with soras; short-billed soras feed on seeds, while the long-billed Virginia rails mostly consume insects.
20. Sora
- Scientific Name: Porzana carolina
Soras are small waterbirds found during summer in the state. They are common around wetlands containing cattails and patches of open water.
Soras use a descending “whinny” call between mated pairs and when establishing territories. They also have a “ker-wee” call for attracting mates and are most active during dawn and dusk.

The best times to spot soras are early in the mornings or late in the evenings when they’re more likely to come out from the thick plants in search of food.
20. American Bittern
- Scientific Name: Botaurus lentiginosus
American bitterns are well-camouflaged solitary birds that spend summers throughout most of PA before departing south to winter. These birds prefer large cattail or sedge marshes and wet meadows.
More often heard than seen, they are mainly nocturnal with most of the activity happening around dusk. American bitterns have a distinctive booming call that resembles a congested pump that people describe as “oong-kach-oonk.“

21. Least Bittern
- Scientific Name: Ixobrychus exilis
Least bitterns are one of the smallest heron species in the world. They can be heard in western parts of PA during their breeding season from May to August; they are more active at dawn and dusk and less vocal in windy or rainy conditions.
Least bitterns are common around marshes with a mix of open water and vegetation, often with cattails, phragmites, or lily pads. Males can be recognized by their soft “coo-coo-coo” and “reek-reek-reek” calls.

Identify them also by their long legs, daggerlike bills, and orange, black, and white plumage.
22. Black-crowned Night Heron
- Scientific Name: Nycticorax nycticorax
Black-crowned night herons can be occasionally heard around wooded swamps, ponds, lakes, and mangroves.
These PA’s bluish birds are now scarce in most parts of the state, with a particular concentration along the Susquehanna and Delaware River corridors in the southeastern counties; the number and size of colonies have recently decreased, especially in the northern and western counties.
Unlike many other herons, they’re active at night or dusk and migrate in flocks during the night. Their name “Nycticorax” means “night raven” in Greek, reflecting their nocturnal habits and crow-like calls.

These herons often bait fish, luring prey with thrown food before striking with their long beaks.
23. Yellow-crowned Night Heron
- Scientific Name: Nyctanassa violacea
Among Pennsylvania’s rarest nesting birds, their only known breeding site is located in an urban setting in Dauphin County. They are accidental visitors elsewhere in the state, particularly in late summer following the breeding season.
Yellow-crowned night-herons are vocal, with various calls like “quawk,” “yup-yup,” and “huh.”
While occasionally seen during the day, they are primarily nocturnal, roosting in trees during daylight and feeding at night, with crabs and crayfish being their main prey.
24. Ovenbird
- Scientific name: Seiurus aurocapilla
Ovenbirds sing regularly at night but at a relatively low song rate. These small migratory songbirds can be heard during summer nights throughout the state.
Lister for their territorial rapid, resounding “tea-cher, tea-cher” song consisting of 8-13 phrases. They also have several short calls, including the “ple-bleep,” “whink,” and high “tsip.”

Ovenbirds got their name from the nest they built called the “oven” – it is a dome-like structure placed on the ground with a side entrance that makes it resemble a Dutch oven.
25. King Rail
- Scientific Name: Rallus elegans
King rails, the largest North American rail species, can be heard singing mostly during the night. They have a chicken-sized body with small heads, short tails, and long necks and legs.
These birds use their long, curved, orange-brown beaks (around 2.3-2.6 inches long) to find food in eastern and western Pennsylvania’s freshwater marshes.
King rails emit low, repeated grunt calls that go “kek-kek-kek.”
They are skilled foragers, using their beaks to probe the mud for aquatic insects and crustaceans. In a courtship display, one male once caught 7 crayfish in 2 hours, offering 5 to his partner.

What Birds Sing At Night In Pennsylvania?
The most common birds that sing at night in Pennsylvania are northern mockingbirds.
Mockingbirds singing all night are often young, unattached males or older males without a mate. In case you want to stop their nighttime singing, try to cover your tree with bird netting or add an owl/hawk cardboard cutout to scare them away.
You might have also heard yellow-breasted chats singing in the darkness as they call out to the females, American robins and their cheery carol, or even barn owls and their bone-chilling screams.
