Wisconsin is home to a diverse array of birds of prey, ranging from majestic hawks to powerful falcons and soaring eagles. This guide is perfect for bird enthusiasts, nature lovers, and anyone interested in spotting these fascinating predators in the Badger State. Whether you’re an avid birder or a casual observer, understanding the different types of raptors can deepen your appreciation and help you identify them in the wild.
Bald Eagle
The Bald Eagle is Wisconsin’s national symbol and a common sight near lakes, rivers, and wetlands. Recognizable by its white head and tail contrasting with a dark brown body, it soars majestically over open water. These eagles primarily feed on fish, diving to capture prey with their powerful talons, and are a symbol of conservation success in the state, having recovered from near-extinction in the 20th century.
Red-tailed Hawk
One of the most widespread raptors in Wisconsin, the Red-tailed Hawk is easily identified by its broad, reddish-brown tail and a characteristic raspy scream. It favors open fields and forests, hunting small mammals such as mice and rabbits from perches or while soaring. Its adaptability to various habitats makes it a common sight throughout the year, especially during the fall migration.
Peregrine Falcon
The Peregrine Falcon is renowned as the fastest bird in the world, capable of reaching speeds over 200 miles per hour during its hunting dives. Once nearly extirpated from Wisconsin due to pesticide use, conservation efforts have helped its numbers rebound, and it now nests on tall cliffs and urban skyscrapers. Its incredible speed and hunting prowess make it a thrilling species for birdwatchers to observe.
Northern Harrier
The Northern Harrier, also known as the Marsh Hawk, is distinguished by its owl-like facial disk and long, slender wings. It often hunts over marshes, prairies, and open fields, swooping low to catch rodents and small birds. Its distinctive flight pattern—gliding low with wings held in a V-shape—sets it apart from other hawks in Wisconsin.
Sharp-shinned Hawk
The Sharp-shinned Hawk is a small but fierce predator, often mistaken for its cousin, the Cooper’s Hawk. It primarily preys on small songbirds, catching them in dense forests and woodlands. Its narrow, rounded tail and swift, darting flight make it a challenging but rewarding bird to identify in the field.
American Kestrel
The American Kestrel is the smallest falcon in North America and is easily recognizable by its colorful plumage—males display blue wings and a rufous back. It often perches on power lines or fence posts, hunting insects, small rodents, and birds. Its adaptability to urban environments makes it a common sight across Wisconsin’s open areas and parks.
Osprey
The Osprey, also called the fish hawk, is a large raptor that specializes in catching fish, often seen hovering over lakes and rivers before plunging feet-first into the water. Its distinctive white head with a dark eye stripe and wingspan of up to six feet make it easy to identify. Ospreys are indicators of healthy aquatic ecosystems and are often seen nesting on man-made platforms or tall trees.
Cooper’s Hawk
The Cooper’s Hawk is a medium-sized bird of prey that favors wooded habitats and urban areas. It preys mainly on small to medium-sized birds, catching them in flight with swift, agile movements. Its rounded wings and long tail help it maneuver through dense branches, making it a skilled hunter in forested environments.
Broad-winged Hawk
The Broad-winged Hawk is a migratory species that passes through Wisconsin in large flocks during spring and fall. It has a compact body, broad wings, and a distinctive dark band on the tail. During migration, they often soar in thermals, providing spectacular viewing opportunities for birders tracking their seasonal journey.
How to Choose
When selecting which bird of prey to focus on or observe, consider factors such as habitat preference, size, flight pattern, and time of year. For instance, if you’re near water, Ospreys and Bald Eagles are prominent, while forests are ideal for Cooper’s Hawks and Sharp-shinned Hawks. Field markings, behavior, and calls are also key identification tools—learning these details can greatly enhance your birdwatching experience. Ultimately, choosing species that are common in your area or during specific seasons will increase your chances of successful sightings.
