This list covers 10 of the most common and intriguing hawk species found in the state, offering detailed insights into their appearance, behavior, and habitat preferences.
Red-tailed Hawk (Buteo jamaicensis)
The Red-tailed Hawk is arguably Pennsylvania’s most recognizable bird of prey. Known for its distinctive brick-red tail, this hawk measures about 18 to 25 inches in length with a wingspan of up to 4.8 feet. It favors open fields and wood edges, often soaring high while searching for small mammals such as mice and rabbits. Its adaptability to various habitats makes it a common sight across the state and a favorite among birdwatchers.
Cooper’s Hawk (Accipiter cooperii)
Cooper’s Hawks are medium-sized raptors, roughly 14 to 20 inches long with a wingspan of 24 to 35 inches. They are known for their swift, agile flight, often navigating through dense forests and suburban areas in pursuit of smaller birds like songbirds and doves. Their barred underparts and rounded tail help distinguish them from similar species. They are particularly active during the fall and winter months when they hunt in residential neighborhoods.
Sharp-shinned Hawk (Accipiter striatus)
The Sharp-shinned Hawk is the smallest of Pennsylvania’s accipiters, measuring about 9 to 13 inches with a wingspan of 16 to 24 inches. Its narrow, pointed wings and squared-off tail allow it to dart swiftly through thick foliage. It primarily preys on small birds and is often seen during migration seasons in wooded areas and bird feeders. Its compact size makes it a challenging but rewarding sight for bird enthusiasts.
Broad-winged Hawk (Buteo platypterus)
Standing out during migration, the Broad-winged Hawk is a medium-sized raptor about 13 to 17 inches long with a wingspan of 3.4 to 3.9 feet. Recognized by its broad wings and dark wrist patches, it favors deciduous forests and wetlands. During migration in spring and fall, thousands of these hawks gather in Pennsylvania to rest and prepare for long flights south or north, making fall migration a spectacular spectacle for observers.
Northern Harrier (Circus hudsonius)
The Northern Harrier, also called the Marsh Hawk, measures 18 to 24 inches in length with a wingspan of 4.2 to 4.8 feet. Its distinctive white rump patch and low, gliding flight make it easily identifiable. Preferring open fields, marshes, and grasslands, it hunts small mammals, insects, and birds by flying low over the ground. Its graceful, silent flight pattern is a delight for birdwatchers in rural and wetland areas.
Red-shouldered Hawk (Buteo lineatus)
With a length of 16 to 24 inches and a wingspan reaching up to 3.8 feet, the Red-shouldered Hawk is known for its striking reddish shoulders and barred chest. It favors mature forests near streams and swamps, where it hunts frogs, insects, and small mammals. Its loud, distinctive call often echoes through woodland areas, making it a favorite among those exploring Pennsylvania’s forested regions.
American Kestrel (Falco sparverius)
The American Kestrel is Pennsylvania’s smallest falcon, measuring 9 to 11 inches long with a wingspan of about 20 inches. Recognizable by its vibrant blue and orange plumage, it perches on wires and posts, hunting insects, small rodents, and birds. Its adaptability to urban and rural environments, along with its striking appearance, makes it a common and exciting sight for birdwatchers.
Harris’s Hawk (Parabuteo unicinctus)
While not as common as other species, Harris’s Hawks have been increasingly spotted in Pennsylvania, especially in the southern parts. They are larger hawks, about 20 to 24 inches long, with distinctive dark brown plumage and banded tails. Known for their cooperative hunting behavior, they often hunt in groups and prefer open woodlands and grasslands. Their unique social hunting style makes them a fascinating subject for bird enthusiasts.
Swainson’s Hawk (Buteo swainsoni)
Typically more common in western North America, Swainson’s Hawks are occasionally seen during migration in Pennsylvania. They are large, about 18 to 22 inches long, with broad wings and a pale underside. During migration, they pass through the state in large flocks, feeding primarily on insects and small mammals. Spotting one in Pennsylvania offers a rare but rewarding experience for avid birdwatchers.
How to Choose
When selecting which hawk to observe or photograph, consider factors like size, plumage, habitat, and behavior. Pay attention to the hawk’s flight pattern, vocalizations, and the environment where it’s seen.
