Pennsylvania is home to a diverse array of owl species, each with unique behaviors, habitats, and appearances. Whether you’re a birdwatcher, nature enthusiast, or simply curious about these nocturnal predators, this list covers the most common and notable owls you might encounter in the state. Discover what makes each species special and how to identify them in the wild.
Great Horned Owl
The Great Horned Owl (Bubo virginianus) is Pennsylvania’s most widespread and powerful owl. Recognizable by its large, tufted ears and piercing yellow eyes, it inhabits forests, swamps, and urban areas. Its deep hooting call is a familiar sound in the night, and it preys on a variety of animals, from rabbits to other birds, making it a top predator in its ecosystem.
Eastern Screech-Owl
The Eastern Screech-Owl (Megascops asio) is a small, adaptable owl often found in wooded suburbs and forests. It has two color morphs—reddish and gray—and is known for its trilling or whinnying calls. Its camouflage plumage helps it blend into tree bark, and it primarily feeds on insects and small mammals, making it a common sight for birders in Pennsylvania.
Barn Owl
The Barn Owl (Tyto alba) is distinguished by its heart-shaped face and ghostly white appearance. Though more common in open farmland and rural areas, it occasionally nests near barns and silos in Pennsylvania. Its haunting screech and exceptional hunting skills for rodents make it an important natural pest control agent.
Barred Owl
The Barred Owl (Strix varia) is a large, majestic owl with striking horizontal and vertical barring on its chest and a rounded head with no ear tufts. It prefers mature forests near water and is known for its distinctive hooting, which sounds like “Who cooks for you, all?” Its diet includes fish, small mammals, and birds, making it a vital part of Pennsylvania’s woodland ecosystems.
Northern Saw-whet Owl
The Northern Saw-whet Owl (Aegolius acadicus) is a tiny, nocturnal owl that often goes unnoticed due to its small size and secretive nature. It has a rounded head, yellow eyes, and a distinctive, repetitive call resembling a saw being sharpened. Found mainly in dense coniferous forests, it preys on insects and small rodents, and is a favorite among dedicated birdwatchers.
Long-eared Owl
The Long-eared Owl (Asio otus) is characterized by its long ear tufts and orange eyes. It favors dense forests and thick brush in Pennsylvania, roosting during the day in conifers or dense foliage. Its haunting, repetitive call and preference for open woodland habitats make it a distinctive species for birders seeking nocturnal surprises.
Short-eared Owl
The Short-eared Owl (Asio flammeus) is a ground-nesting species often seen hunting over open fields and marshes. Its pale face, yellow eyes, and rounded wings distinguish it from other owls. Active during both day and night, it preys on small mammals and is a seasonal visitor in Pennsylvania’s grasslands and agricultural areas.
Northern Hawk Owl
The Northern Hawk Owl (Surnia ulula) is rare in Pennsylvania but occasionally seen in winter. It resembles a small hawk with a long tail and striking facial markings. Preferring coniferous forests, it hunts during the day, feeding mainly on small mammals, and is appreciated by experienced birders for its rarity and striking appearance.
Flammulated Owl
The Flammulated Owl (Psiloscops flammeolus) is an elusive species found in southwestern Pennsylvania’s montane forests. It is small, with a distinctive cinnamon-colored face and dark markings. Active mainly at night, it feeds on insects and small vertebrates and is a prized sighting for dedicated owl enthusiasts due to its secretive nature.
How to Choose
When selecting which owl to observe or study, consider factors like habitat, size, call, and activity patterns. Larger owls like the Great Horned and Barred Owls are easier to spot due to their size and distinctive calls. Smaller species such as the Saw-whet and Flammulated owls require patience and often nocturnal or dawn observation. Pay attention to your location, time of day, and the type of environment—woodlands, open fields, or urban areas—to increase your chances of seeing or hearing specific species.
