Pennsylvania is a haven for bird of prey enthusiasts, boasting a diverse population of raptors that inhabit its forests, mountains, and open fields. Whether you’re a seasoned birdwatcher or a curious nature lover, understanding the key species of these majestic birds can deepen your appreciation for Pennsylvania’s rich avian biodiversity. This list covers the most common and notable birds of prey in the state, offering detailed insights into their appearance, behavior, and why they are worth observing.
Bald Eagle
The Bald Eagle (Haliaeetus leucocephalus) is Pennsylvania’s national bird and a symbol of American freedom. Recognizable by its white head and tail contrasting with a dark brown body, this large raptor can have a wingspan of up to 7 feet. Bald Eagles are often spotted near lakes and rivers, especially during winter months when they hunt for fish, their primary diet. Their presence signifies healthy ecosystems, making them a favorite among birdwatchers and conservationists alike.
Northern Harrier
The Northern Harrier (Circus hudsonius) is notable for its distinctive low-flight hunting style over open fields and marshes. With a slim body, long wings, and a long tail, it often appears as a grayish or brownish bird with a white rump patch visible in flight. These birds are highly adaptable, nesting in wetlands and agricultural areas across Pennsylvania. Their keen eyesight and agile flight make them fascinating to observe during spring and fall migrations.
Red-tailed Hawk
The Red-tailed Hawk (Buteo jamaicensis) is one of Pennsylvania’s most common and recognizable raptors. It features a rich, reddish-brown tail and broad wings, often seen soaring high above fields and woodlands. They are versatile predators, hunting small mammals, birds, and reptiles, and are often spotted perched on roadside posts or trees. Their widespread presence makes them an accessible and exciting species for birdwatchers to study.
American Kestrel
The American Kestrel (Falco sparverius) is the smallest falcon in North America, easily identified by its colorful plumage—males with slate-blue wings and orange bodies, females with more subdued tones. They are quick, agile hunters that catch insects, small birds, and rodents, often seen hovering over open fields. Kestrels are particularly active during spring and summer and are a delight to observe for those interested in falconry or quick-moving birds of prey.
Osprey
The Osprey (Pandion haliaetus) is a large, fish-eating raptor with a distinctive white underside and dark eye stripe. Commonly nesting on tall poles, trees, and cliffs near water bodies, they are expert fishers, diving feet-first into lakes, rivers, and coastal areas. Pennsylvania’s many lakes and reservoirs provide ideal habitat for Ospreys, making them a rewarding sight for birdwatchers during the warmer months.
Peregrine Falcon
The Peregrine Falcon (Falco peregrinus) is renowned for its incredible speed, reaching over 200 mph during dives. Once nearly extirpated from Pennsylvania due to pesticide use, conservation efforts have led to a resurgence, especially around urban areas where they nest on tall buildings. Their swift flight and striking appearance—blue-gray back and barred underparts—make them one of the most exciting birds of prey to observe in the state.
Sharp-shinned Hawk
The Sharp-shinned Hawk (Accipiter striatus) is a small but fierce raptor that specializes in hunting small birds in dense forests. It has a short, squared tail and bluish-gray upperparts with orange bars on the chest. During fall migrations, these hawks are frequently seen darting through woodlands and are a favorite among experienced birders for their agility and speed.
Broad-winged Hawk
The Broad-winged Hawk (Buteo platypterus) is known for its impressive migration in large flocks during spring and fall. They have a compact body, broad wings, and a distinctive banded tail. These hawks prefer deciduous forests and are often seen soaring in thermals over the Appalachian Mountains, providing spectacular sights for those who seek to witness migration phenomena.
Cooper’s Hawk
The Cooper’s Hawk (Accipiter cooperii) is a medium-sized raptor that has adapted well to suburban environments. Recognizable by its rounded tail and piercing yellow eyes, it preys on medium-sized birds and small mammals. Its preference for woodlots and residential areas makes it more visible to urban birdwatchers, especially during the breeding season.
How to Choose
When selecting which bird of prey to observe or focus on, consider factors like habitat, size, flight style, and seasonality. For example, if you’re near water, Ospreys and Bald Eagles are excellent choices. If you prefer forested areas, look for Sharp-shinned or Cooper’s Hawks. Also, think about the time of year—some species, like Broad-winged Hawks, are more prominent during migration, while others, like the Red-tailed Hawk, are visible year-round. Binoculars and field guides tailored to Pennsylvania species can greatly enhance your viewing experience.
