8 Types of Owls in Pennsylvania
Eastern Screech Owl
The Eastern Screech Owl (Megascops asio) is a small, nocturnal owl species native to Pennsylvania. Despite its small size, ranging from 6 to 10 inches in length, this owl is a formidable predator, preying primarily on insects, small mammals, and birds. Its cryptic plumage, which can range from reddish-brown to gray, helps it blend seamlessly into its woodland habitat.
Named for its distinctive whinnying or trilling call rather than a true screech, the Eastern Screech Owl is known for its vocalizations during the breeding season.
These owls are cavity nesters, often utilizing abandoned woodpecker holes or nest boxes for shelter. They are also adaptable to suburban and urban environments, nesting in parks and residential areas with mature trees.
Great Horned Owl
The Great Horned Owl (Bubo virginianus), a majestic and formidable predator, commands respect as one of Pennsylvania’s largest and most iconic owl species.
Named for the prominent ear tufts resembling horns atop its head, this owl boasts a wingspan of up to five feet and can stand over two feet tall. With its keen vision and powerful talons, it preys upon a wide range of animals, including rabbits, rodents, birds, and even larger prey like skunks and young deer.
Adapted to diverse habitats ranging from forests to deserts, the Great Horned Owl is a versatile hunter capable of thriving in both rural and urban environments. Its deep hooting calls resonate through the night, signaling its presence in the darkness.
Barred Owl
The Barred Owl (Strix varia) graces Pennsylvania’s woodlands with its distinct hooting call and striking appearance. Recognized by its mottled brown plumage with horizontal barring on its chest, this medium-sized owl stands out against the backdrop of deciduous and mixed forests.
With a wingspan of up to 44 inches, the Barred Owl possesses exceptional flying capabilities, allowing it to navigate dense forests with ease as it hunts for its primary prey, which includes small mammals, birds, amphibians, and insects.
Unlike some other owl species, the Barred Owl is known for its adaptability to various habitats, ranging from deep forests to urban parks and suburban neighborhoods.
Barn Owl
The Barn Owl (Tyto alba) casts an ethereal presence over Pennsylvania’s agricultural landscapes and grasslands. Characterized by its heart-shaped facial disc and golden-brown plumage, this medium-sized owl possesses a wingspan of up to 42 inches.
Renowned for its silent flight, aided by specialized feathers that dampen noise, the Barn Owl is an expert nocturnal hunter, preying predominantly on rodents such as mice, voles, and shrews.
Unlike many owl species, the Barn Owl often nests in man-made structures such as barns, silos, and abandoned buildings, hence its name. Its eerie screeches and rasping calls echo through the night as it establishes its territory and communicates with mates.
Northern Saw-whet Owl
The Northern Saw-whet Owl (Aegolius acadicus) may be diminutive in size, but its presence in Pennsylvania’s woodlands is unmistakable.
Measuring only 7 to 8 inches in length, this small owl possesses a round facial disc and distinctive white “V” markings on its face. Named for its repetitive sawing call, reminiscent of a saw being sharpened, this nocturnal hunter primarily feeds on small mammals such as mice and voles.
Although elusive and cryptically colored to blend into its surroundings, the Northern Saw-whet Owl is occasionally spotted during migration periods or by keen-eyed observers. It nests in tree cavities and relies on dense coniferous forests for roosting and hunting.
Long-eared Owl
The Long-eared Owl (Asio otus), with its distinctive long ear tufts, adds a touch of mystery to Pennsylvania’s woodlands and open landscapes. Though relatively slender, with a wingspan of up to 40 inches, this owl possesses remarkable hunting skills, preying primarily on small mammals such as mice, voles, and shrews.
Its cryptic plumage, a mix of brown and buff tones with intricate patterning, provides excellent camouflage among dense foliage or against tree bark.
Despite its widespread distribution across North America, the Long-eared Owl is a secretive species, often roosting in dense vegetation during the day and becoming active at night. Its low, hooting calls serve as communication between individuals and during courtship rituals.
Short-eared Owl
The Short-eared Owl (Asio flammeus) brings a touch of grace to Pennsylvania’s grasslands and marshes with its buoyant flight and distinctive facial disc.
Despite its name, which refers to its relatively short ear tufts, this medium-sized owl boasts a wingspan of up to 40 inches and a mottled brown plumage that blends seamlessly with its surroundings. Primarily a crepuscular hunter, the Short-eared Owl preys upon small mammals like voles and mice, as well as birds and insects.
Unlike some owl species, the Short-eared Owl is often observed hunting during daylight hours, making it more visible to observers. Its raspy barks and hoots echo across the open landscapes, serving as territorial calls and communication with mates.
Eastern Whip-poor-will
The Eastern Whip-poor-will (Antrostomus vociferus) adds a touch of enchantment to Pennsylvania’s woodland edges and open spaces with its haunting nocturnal calls.
Although often mistaken for an owl due to its nocturnal habits and cryptic plumage, this medium-sized nightjar is distinct in its appearance and behavior. Named for its repetitive “whip-poor-will” call, the Eastern Whip-poor-will is most vocal during the breeding season, when males advertise their territories to potential mates.
With its mottled brown and gray plumage, the Eastern Whip-poor-will blends seamlessly into its surroundings, making it challenging to spot during daylight hours.
Final Words
Pennsylvania’s diverse landscapes provide habitats for a captivating array of owl species, each playing a unique role in the state’s ecosystems. From the iconic Great Horned Owl to the elusive Northern Saw-whet Owl, these majestic birds inspire wonder and awe.
Even though they face obstacles including pollution, habitat loss, and human disturbance, public awareness campaigns and conservation initiatives are essential to their existence. We can save Pennsylvania’s owl populations for owl enthusiasts to adore and appreciate in the future by encouraging appropriate environmental practices, conserving nesting places, and maintaining natural ecosystems.
