Different Types of Birds of Prey Found in Delaware
Bald Eagle

The Bald Eagle is one of the most iconic raptors in the United States and is increasingly common throughout Delaware. Its unmistakable appearance—dark brown body, bright white head and tail, and large yellow bill—makes it easy to identify even at great distances. Immature birds lack the crisp white head and tail and instead display mottled brown plumage.
Adults are large, measuring 28 to 40 inches long with wingspans that often exceed seven feet. Their immense size becomes especially obvious when they soar over rivers or glide above marshes. Bald Eagles use slow, powerful wingbeats and broad wings that help them stay aloft with minimal effort.
In Delaware, Bald Eagles thrive near waterways, especially along the Delaware River, coastal marshes, tidal creeks, and large reservoirs. They feed mainly on fish but also scavenge carrion and occasionally steal food from other birds. Nesting activity in Delaware has grown dramatically due to conservation efforts and abundant wetland habitat.
Fun fact: Bald Eagles build some of the largest nests of any bird in the world, often weighing hundreds of pounds and reused for many years.
Golden Eagle

The Golden Eagle is much rarer in Delaware and is typically seen only during winter or migration. It is recognized by its dark brown body, golden nape, and long, broad wings that taper slightly at the tips. This species has a powerful, regal appearance that sets it apart from other large birds of prey.
Golden Eagles measure between 27 and 33 inches long and possess wingspans of six to seven and a half feet. Their size is similar to Bald Eagles, but their silhouettes differ: Golden Eagles have smaller heads, longer tails, and slightly narrower wings. They are strong, fast fliers capable of soaring for long periods.
In Delaware, Golden Eagles appear mostly in open farmlands, coastal plains, and large grassland areas where they can hunt easily. These winter visitors often migrate through the Appalachian region and occasionally drift into the state during colder months. Sightings remain special due to their rarity.
Fun fact: Golden Eagles have incredible eyesight, allowing them to spot prey like rabbits from more than a mile away.
Red-tailed Hawk

The Red-tailed Hawk is the most common hawk in Delaware and one of the easiest raptors to identify. Its broad wings, pale chest, and distinctive brick-red tail create a recognizable profile as it circles above fields and highways. Immature birds have brown banded tails, so age determines tail coloration.
Adults typically measure 18 to 26 inches in length with wingspans of 45 to 52 inches. Their wide wings and short, broad tails allow them to soar effortlessly in open air. Red-tailed Hawks often perch on utility poles or tree snags, scanning for rodents with remarkable patience.
This species is found throughout Delaware in forests, farmland edges, suburban neighborhoods, and coastal marsh regions. It is highly adaptable and takes advantage of open habitats where prey such as mice, voles, squirrels, and snakes are plentiful. Red-tailed Hawks remain in Delaware year-round and are visible in every season.
Fun fact: Red-tailed Hawk calls are often used in movies as the default “eagle sound,” even though eagles sound very different.
Red-shouldered Hawk

The Red-shouldered Hawk is slightly smaller and more colorful than the Red-tailed Hawk. Its rich reddish chest, black-and-white banded tail, and bold checkered wings make it one of the most visually striking hawks in Delaware. The warm rufous tones on its shoulders give the species its name.
Adults measure around 17 to 23 inches long with wingspans between 37 and 43 inches. They are agile fliers, often weaving through forests with smooth, buoyant wingbeats. Their high-pitched, repeating call—kee-yer—is a classic sound in wooded wetlands during spring and summer.
In Delaware, Red-shouldered Hawks prefer riparian forests, swampy woodlands, and floodplain habitats. They are strongly associated with water and are commonly seen near creeks, streams, and forested marshes. Their diet includes frogs, snakes, crayfish, and small mammals, which thrive in these wet environments.
Fun fact: Red-shouldered Hawks often reuse the same nesting territory for years, returning to the same patch of forest each breeding season.
Cooper’s Hawk

The Cooper’s Hawk is a mid-sized, sleek, and incredibly agile raptor known for hunting birds in tight forest spaces. It has a rounded head, long tail, and blue-gray back complemented by a finely barred, reddish-orange chest. When perched, it has a sharp, intense stare that immediately captures attention.
Adults measure 14 to 20 inches long with wingspans of 24 to 35 inches. Their long, narrow tails and short, rounded wings make them exceptional at sudden bursts of speed. Cooper’s Hawks are masters of maneuvering between trees, often chasing prey through dense vegetation.
In Delaware, this species is frequently spotted in suburbs, woodlots, city parks, and backyard feeding areas where small birds gather. Their adaptability allows them to live near humans more easily than many other hawks. Coop’s Hawks are year-round residents in the state and become especially visible during fall migration.
Fun fact: Cooper’s Hawks sometimes chase prey at such high speeds through trees that they collide with branches, yet they have evolved flexible bones that reduce injury.
Sharp-shinned Hawk

The Sharp-shinned Hawk is the smallest hawk in Delaware, but its size does not limit its speed or agility. It has a slender body, long legs, and a narrow, pointed tail that help it maneuver quickly through forests. Adults display blue-gray upperparts and orange-barred chests, while juveniles show brown streaking.
Most adult Sharp-shinned Hawks measure 9 to 13 inches long with wingspans between 17 and 22 inches. Their rounded wings and long tail create a compact, dart-like profile when they fly through wooded areas. Because of their small size, they are often mistaken for large songbirds at a distance.
In Delaware, Sharp-shinned Hawks appear regularly during fall migration and are most visible around backyard bird feeders, where they ambush small birds. They also frequent wooded parks, pine forests, and edges of suburban neighborhoods. Some remain through winter, especially in areas with strong prey availability.
Fun fact: Sharp-shinned Hawks can change direction so quickly that they sometimes twist mid-air to avoid branches during high-speed pursuits.
Osprey

The Osprey is one of Delaware’s most recognizable birds of prey and is found abundantly along the coast and tidal rivers. Its white head with a bold dark eye stripe, brown upperparts, and long, angled wings make it easy to identify even from far away. When hovering over water, its sharp talons dangle slightly as it prepares to dive.
Ospreys measure around 20 to 26 inches long with impressive wingspans that reach five to six feet. Their wings are long and narrow, giving them a distinctive “M” shape when seen from below. Unlike most raptors, Ospreys have reversible outer toes that allow them to grasp slippery fish with precision.
In Delaware, Ospreys thrive around estuaries, bays, tidal marshes, and inland reservoirs. They nest on platforms, channel markers, utility poles, and even dedicated artificial towers placed for conservation. Their diet is almost entirely fish, making Delaware’s coastal environment ideal for their year-round presence.
Fun fact: Ospreys are sometimes called “sea hawks” because over 99 percent of their diet consists of fish.
Turkey Vulture

The Turkey Vulture is one of the most common soaring birds in Delaware and is easy to recognize by its dark body, long two-toned wings, and bright red featherless head. Its wings form a slight “V” shape while gliding, and it wobbles gently as warm thermals lift it high into the sky with minimal effort.
Turkey Vultures are large birds, measuring 25 to 32 inches long with wingspans reaching six feet. Their long, broad wings allow them to stay aloft by riding rising columns of warm air. Instead of flapping frequently, they rely on soaring, which makes them appear almost motionless against the sky.
These vultures are widespread throughout Delaware, found in farmlands, forests, coastal plains, and even near towns. They primarily feed on carrion, using an excellent sense of smell to locate dead animals—a trait rare among birds. Their presence helps keep ecosystems clean and reduces disease spread.
Fun fact: Turkey Vultures cool themselves in summer by defecating on their legs, a behavior called “urohidrosis.”
Black Vulture

The Black Vulture is stockier and shorter-tailed than the Turkey Vulture, giving it a more compact and powerful appearance. It has black feathers, gray-black skin on the head, and white patches on the tips of its wings that are visible in flight. Its wingbeats are stronger and more frequent compared to the Turkey Vulture.
Adults measure 22 to 29 inches long with wingspans of nearly five feet. Their silhouette features broad wings and a short, rounded tail. While they soar less efficiently than Turkey Vultures, they are stronger fliers and often take off quickly from perches.
In Delaware, Black Vultures are common in southern and central regions, especially near farmland, landfills, and open woodlands. They rely heavily on eyesight rather than smell and often follow Turkey Vultures to carcasses. Their social groups are tighter, and they frequently feed together in groups.
Fun fact: Black Vultures are highly social and even share food with relatives, recognizing individual family members.
Northern Harrier

The Northern Harrier is a graceful, low-flying raptor found in Delaware’s grasslands, marshes, and open fields. It is easily recognized by its long wings, slim body, and distinctive white patch at the base of the tail. Males are pale gray, while females and juveniles display brown plumage with streaked underparts.
Adults measure 18 to 20 inches long with wingspans between 40 and 47 inches. Their long, rounded wings and buoyant flight style help them glide low above the ground while hunting. They listen for prey with their owl-like facial disk, which channels sound toward their ears.
In Delaware, Northern Harriers are most common in winter and during migration. They sweep across salt marshes, agricultural fields, and conservation areas, flying just a few feet above the ground as they search for rodents and small birds. Their slow, quartering flight makes them unique among hawks.
Fun fact: Northern Harriers are one of the few raptors that rely heavily on hearing as well as sight when hunting, thanks to their specialized facial disk.
Peregrine Falcon

The Peregrine Falcon is one of the most thrilling raptors to watch in Delaware, especially during migration when their numbers surge along the coast. Its sharp black facial markings, blue-gray upperparts, and barred underside create a sleek, unmistakable silhouette. When perched, its muscular chest and long pointed wings show the bird’s aerodynamic design.
Adults measure 14 to 19 inches long with wingspans reaching up to 43 inches. Their body shape is built entirely for speed, which becomes clear in flight. Peregrines accelerate quickly with strong wingbeats, then glide gracefully before diving in a dramatic stoop. These dives can exceed 200 miles per hour, making them the fastest animals on Earth.
In Delaware, Peregrine Falcons are most commonly seen during fall and spring migration, especially along the Delaware Bay, barrier beaches, and large coastal wetlands. Some individuals winter in the state, often perching on tall buildings, bridges, or coastal towers. They hunt shorebirds, pigeons, and small ducks with incredible precision.
Fun fact: Peregrines have special structures in their nostrils that allow them to breathe normally while diving at extreme speeds.
American Kestrel

The American Kestrel is the smallest falcon in Delaware and one of the most colorful birds of prey in North America. Males display blue-gray wings and a rusty back, while females show more brown patterning. Both sexes have two bold black stripes on each side of the face, giving them a sharp, expressive look.
Kestrels typically measure 8 to 12 inches long with wingspans of 20 to 24 inches. Despite their small size, they are highly skilled fliers capable of hovering in place as they scan for insects and small rodents. They perch frequently on wires, fence posts, and open snags where they have an unobstructed view of the ground.
In Delaware, American Kestrels appear in open fields, farmlands, grassy roadsides, and coastal prairies. They are especially common in winter when individuals from farther north join local birds. Their diet includes grasshoppers, beetles, lizards, mice, and small birds, making them active hunters throughout the day.
Fun fact: American Kestrels can see ultraviolet light, which helps them track rodent urine trails across fields.
Merlin

The Merlin is a small, powerful falcon with a compact build and rapid, direct flight. Males are slate-gray above, while females and juveniles show brown tones. Their piercing dark eyes and heavily streaked chest give them a fierce, intense expression, fitting for a bird that specializes in high-speed chases.
Adults measure about 9 to 12 inches long with wingspans of 20 to 26 inches. Their wingbeats are fast and strong, making them appear heavier and more muscular in flight compared to the lighter kestrel. Unlike kestrels, Merlins rarely hover—they prefer swift, low pursuits that surprise small songbirds or shorebirds.
In Delaware, Merlins are primarily seen during migration and winter near beaches, dunes, open grasslands, and urban areas where prey is abundant. Their presence along the coast becomes especially noticeable on windy days when they hunt migrating songbirds.
Fun fact: Merlins sometimes hunt cooperatively in loose pairs, coordinating their movements to scatter flocks of birds.
Barn Owl

The Barn Owl is one of Delaware’s most enchanting nocturnal raptors, easily recognized by its pale white, heart-shaped facial disk and buff-colored wings. Its ghostlike flight and silent wingbeats allow it to surprise prey in complete darkness. When seen perched, it often appears slender and elongated with a calm, almost otherworldly expression.
Barn Owls usually measure 13 to 15 inches in length with wingspans reaching 40 inches. They fly silently thanks to soft-edged feathers that eliminate turbulence noise. Their long legs and sharp talons help them capture rodents with remarkable accuracy. Their calls include harsh screeches rather than hoots.
In Delaware, Barn Owls favor open farmland, marsh edges, grasslands, and rural structures such as barns, silos, and abandoned buildings. They rely heavily on healthy rodent populations and often nest in cavities or man-made boxes placed for conservation. They are most often detected at night when hunting low over fields.
Fun fact: Barn Owls can locate prey strictly by sound, even in total darkness, thanks to asymmetrical ears that pinpoint the direction of small animals.
Great Horned Owl

The Great Horned Owl is one of the most powerful and widespread raptors in Delaware. It is easily recognized by its large ear tufts, yellow eyes, and deep hooting call that resonates through forests after sunset. Its thick, mottled plumage helps it blend into tree bark, making it difficult to spot during the day.
Adults measure 18 to 25 inches long with wingspans of up to 5 feet. Their broad wings and strong flight muscles allow them to glide silently and strike with incredible force. Great Horned Owls have one of the strongest grips of any raptor, capable of taking prey larger than themselves.
In Delaware, they occupy forests, wooded neighborhoods, parklands, marsh edges, and farmland. Their adaptability allows them to thrive near human settlements, and they often nest in old hawk or crow nests, tree cavities, or even cliff ledges. They hunt at night, relying on sharp vision and quiet flight to ambush mammals, birds, and reptiles.
Fun fact: Great Horned Owls are so powerful that they can hunt skunks, being one of the few predators not deterred by the smell.
Barred Owl

The Barred Owl is one of Delaware’s most vocal woodland owls, instantly recognizable by its rich brown-and-white vertical barring and large dark eyes. Unlike owls with yellow eyes, the Barred Owl has a softer, rounded facial expression. Its famous call—often rendered as “Who cooks for you? Who cooks for you-all?”—echoes through wetlands and deep forests.
Adults measure 17 to 20 inches long with wingspans reaching about 40 to 43 inches. Their flight is completely silent thanks to specialized feathers that muffle sound. When gliding between trees, they appear broad-winged and buoyant, giving them excellent maneuverability in forested areas.
In Delaware, Barred Owls thrive in mature forests, swampy woodlands, river corridors, and areas rich in large trees with natural cavities. They hunt small mammals, amphibians, reptiles, and birds, often perching quietly before making a swift, silent strike. Their tolerance for moist habitats makes them especially common near freshwater wetlands.
Fun fact: Barred Owls rarely migrate; most individuals stay within the same territory for life, sometimes for more than a decade.
Eastern Screech Owl

The Eastern Screech Owl is a small, cryptic owl that blends perfectly into tree bark. It comes in two color morphs—gray and reddish-brown—and both forms are common in Delaware. Its large ear tufts and patterned plumage allow it to disappear into tree cavities during the day, making it one of the hardest owls to spot.
Adults measure 6 to 10 inches long with wingspans of 18 to 24 inches. Despite their small size, they are fierce predators capable of capturing insects, small rodents, and even small birds. Their call is a soft, haunting trill rather than a hoot, which often alerts birdwatchers to their presence.
In Delaware, Eastern Screech Owls inhabit woodlots, suburban neighborhoods, city parks, orchards, and river-edge forests. They rely heavily on tree cavities for nesting and roosting and will readily use nest boxes placed by homeowners or conservationists. Their adaptability makes them one of the state’s most widespread owls.
Fun fact: Eastern Screech Owls sometimes store uneaten prey in cavities, effectively creating small “pantries” for later meals.
Broad-winged Hawk

The Broad-winged Hawk is best known for its spectacular fall migration, when thousands travel south in large swirling groups called “kettles.” This hawk has a compact build, reddish-brown head, and bold black-and-white tail bands that make it easy to distinguish from other soaring raptors. When perched, it appears smaller and rounder than many of the state’s other hawks.
Adults typically reach 13 to 17 inches in length with wingspans of 31 to 39 inches. Their broad wings and short tails give them excellent soaring ability, allowing them to ride thermals effortlessly during migration. Their flight is steady, and they rarely flap when rising on warm air currents.
In Delaware, Broad-winged Hawks are mostly seen during fall migration, especially at known hawk-watching sites along ridges and coastal flyways. Their breeding range is mostly north and west of the state, so sightings outside migration are uncommon. They favor forests but can appear almost anywhere during their southbound journey.
Fun fact: During peak migration, a single hawk-watch site in the Northeast can count tens of thousands of Broad-winged Hawks in a single day.
Rough-legged Hawk

The Rough-legged Hawk is a winter visitor in Delaware, arriving from the Arctic tundra. This species is recognized by its feathered legs, pale underwings with dark patches, and long wings that create a slender silhouette. Plumage varies widely, with both light and dark morphs possible, adding to its visual appeal.
Adults generally measure 18 to 23 inches long with wingspans of 52 to 54 inches. Their flight style involves slow, deep wingbeats and hovering behavior reminiscent of kestrels. The feathered legs help them stay warm in frigid climates and distinguish them from most other hawks.
In Delaware, Rough-legged Hawks appear in open fields, winter wetlands, and large agricultural areas, particularly in the northern and western parts of the state. They hunt small mammals like voles and typically fly low over expansive fields, scanning for movement.
Fun fact: Rough-legged Hawks can hover in place even in strong winds, a behavior rarely seen in large hawks.
Swainson’s Hawk

Swainson’s Hawk is a rare and exciting find in Delaware, typically appearing only during migration. This species displays a slender body, long wings, and a dark chest bib, though color forms may vary. Its long-distance migration is one of the most impressive of any raptor in the Western Hemisphere.
Adults measure about 18 to 22 inches long with wingspans of 48 inches or more. They have graceful, buoyant flight styles and often soar in circles while searching for rising thermals. Their slim shape and pointed wings help set them apart from bulkier buteos like the Red-tailed Hawk.
In Delaware, sightings are uncommon and usually occur during fall migration in open habitats such as coastal fields, marsh edges, and large farmlands. Most individuals migrate through the central United States, so only a few drift eastward into Delaware.
Fun fact: Swainson’s Hawks migrate as far as Argentina, traveling more than 10,000 miles round trip each year.
Northern Goshawk

The Northern Goshawk is one of the rarest winter raptors to appear in Delaware, typically showing up only during irruption years or severe cold spells. This powerful forest hawk has broad shoulders, a long tail, and a fierce expression marked by bold white eyebrows. Its slate-gray upperparts and finely barred underparts make the adult bird particularly striking.
Adults measure 20 to 26 inches long with wingspans ranging from 40 to 46 inches. Their wings are built for quick acceleration, while the long tail allows tight maneuvering between trees. Juveniles look different, showing brown streaking and less contrast overall, which sometimes leads to confusion with large accipiters.
In Delaware, Northern Goshawks are usually found deep within mature forests, far from human activity. Their secretive nature makes them difficult to detect even when present. They hunt squirrels, rabbits, and medium-sized birds, often ambushing prey with surprising power and speed.
Fun fact: Goshawks are known for fiercely defending their nests and are considered one of the most aggressive hawks when threatened.
Short-eared Owl

The Short-eared Owl is an elegant winter visitor to Delaware’s open landscapes, instantly recognizable by its mottled brown plumage and pale face with shadowed eye patches. Its name comes from the tiny, barely visible ear tufts that often lie flat against the head. In flight, the owl looks buoyant and moth-like with long wings and smooth, flowing wingbeats.
Adults measure between 13 and 17 inches long with wingspans of 34 to 40 inches. Their large wings make them excellent gliders capable of hunting close to the ground. They are crepuscular and often active at dawn and dusk, though in winter they may also fly during the day.
In Delaware, Short-eared Owls prefer coastal marshes, large meadows, and wide grasslands. They can often be seen patrolling low over fields as they search for voles and mice. Some individuals winter regularly in well-known open spaces and protected refuges.
Fun fact: Short-eared Owls are one of the few owl species worldwide that nest directly on the ground.
Long-eared Owl

The Long-eared Owl is one of Delaware’s most secretive owls, spending much of its time roosting in thick conifer stands or dense woodland edges. Its long ear tufts, which stand upright when the bird is alert, give it a distinctive silhouette. The mottled brown and black plumage allows it to blend seamlessly into tree branches.
Adults measure 13 to 16 inches long with wingspans of 35 to 39 inches. Their tall, slender posture and orange facial disks help separate them from other owl species. At night, they fly silently with deep wingbeats and rely heavily on stealth to catch small mammals.
In Delaware, Long-eared Owls are rarely detected except by experienced birders who locate winter roosts. They prefer secluded forests, cedar groves, and overgrown thickets. Their presence often goes unnoticed because they remain motionless during the day and roost in groups known as “communal roosts.”
Fun fact: Long-eared Owls can change their posture—stretching tall or compressing low—to better camouflage themselves depending on their surroundings.
Snowy Owl

The Snowy Owl is an unforgettable sight in Delaware, appearing unpredictably during winter irruption years when northern populations move south in search of food. This large, stunning owl is pure white with varying amounts of dark barring depending on age and sex. Its yellow eyes stand out vividly against the bright plumage.
Snowy Owls measure 20 to 28 inches long with wingspans of 4.5 to 5.5 feet. Built for life on the Arctic tundra, they have thick feathers covering even their legs and toes. Their flight is strong and direct, more like a hawk than a typical owl.
In Delaware, Snowy Owls favor open habitats that resemble the tundra, such as beaches, dunes, airports, and large agricultural fields. They hunt by day and may remain perched in visible places for hours. Because these owls move unpredictably, every winter brings a different number of sightings.
Fun fact: Snowy Owls can detect prey hidden under snow using both sound and sight, allowing them to hunt even in harsh northern conditions.
Northern Saw-whet Owl

The Northern Saw-whet Owl is the smallest owl in Delaware and one of the most challenging to find. With its round head, lack of ear tufts, and big yellow eyes, it has a charming appearance. Its brown body with white facial streaks blends perfectly into dense woodland, making it extremely well-camouflaged.
Adults measure only 7 to 8 inches long with wingspans of 16 to 18 inches. Despite their tiny size, they are efficient nighttime hunters. Their soft, repetitive “toot-toot-toot” call gives away their presence during migration and early winter but becomes difficult to detect once they settle into winter roosts.
In Delaware, Saw-whet Owls are most often encountered during fall migration when they move through wooded areas and coastal forests. During winter, they hide in dense evergreen patches, remaining motionless for most of the day. Their preferred prey includes small rodents and occasionally small birds.
Fun fact: The species gets its name from its call, which early settlers thought sounded like someone sharpening a saw on a whetstone.
Best Time to Observe Birds of Prey in Delaware
Birds of prey can be seen throughout the year in Delaware, but certain seasons offer far better opportunities depending on the species you want to find. Spring and fall migration are the most active periods overall. During these months, the sky fills with hawks, falcons, and even rare migrants passing through the Atlantic Flyway. Broad-winged Hawks and Merlins peak in fall, while Ospreys and many accipiters become highly visible in spring.
Winter is a prime season for spotting northern visitors such as Rough-legged Hawks, Short-eared Owls, Snowy Owls, and the occasional Northern Goshawk. Open farmland, coastal marshes, and large meadows come alive with raptors gliding low over the ground in search of prey. Cold, clear mornings after a storm often create perfect viewing conditions.
Summer belongs to resident species like Red-tailed Hawks, Red-shouldered Hawks, Ospreys, Great Horned Owls, and Eastern Screech Owls. This is also the best time to see young raptors learning to fly and hunt. Early mornings are especially productive before temperatures rise and thermals develop.
Weather plays an important role as well. Warm days with strong thermals draw soaring hawks high into the sky, while overcast or calm mornings keep owls and accipiters closer to the ground. If you want the best diversity, plan your outings around seasonal transitions, especially September through November and March through May.
Best Places to See Birds of Prey in Delaware
Delaware offers a wide range of habitats that attract raptors, from tidal marshes to deep forests. One of the top hotspots is Bombay Hook National Wildlife Refuge, where visitors regularly see Bald Eagles, Northern Harriers, Ospreys, and migrating falcons. Its open wetlands and vast views make it ideal for scanning the sky.
Another excellent place is Prime Hook National Wildlife Refuge, which supports numerous hawks in fall and winter. The marshes here are reliable for Harriers and Short-eared Owls, especially near dusk. Visitors often report multiple raptor species in a single outing.
Along the coast, Cape Henlopen State Park is a prime migration corridor. Peregrine Falcons, Merlins, Ospreys, and Broad-winged Hawks move through the area in large numbers during fall. The dunes and beach edges mimic open tundra, making them a surprising hotspot for Snowy Owls during irruption years.
For woodland species, White Clay Creek State Park and Lums Pond State Park host Barred Owls, Red-shouldered Hawks, Cooper’s Hawks, and Eastern Screech Owls. The dense forests and mature trees provide ideal roosting and nesting areas.
