The American Kestrel, often recognized as the smallest and most brightly colored falcon in North America, exhibits a stunning array of rufous, blue and gray hues in its plumage. This bird, ranging in size from a mere 22 to 31 cm, carries distinct black facial markings that contrast with its white cheeks and has blue gray wings. Despite its small stature, the American Kestrel is a formidable predator, employing a unique hunting strategy that involves hovering at a height before swooping down on prey, primarily consisting of insects, small mammals, and occasionally small birds.
Residing predominantly in North and South America, the American Kestrel exhibits a preference for open habitats such as meadows, grasslands, and deserts. They are also found in both urban and suburban environments, nesting in cavities in trees, cliffs, buildings, and other structures. Kestrels are monogamous, with both sexes participating in the courtship displays that involve aerial acrobatics and feeding rituals. Nesting duties are a shared responsibility, with the male initially scouting for suitable locations and the female making the final selection. Both parents contribute to the incubation of the eggs and care of the young, ensuring the perpetuation of this captivating species.
Bald Eagle (Haliaeetus leucocephalus)
Bald Eagle Sound
Scientific Name: Haliaeetus leucocephalus
Length: 28–40 in
Wingspan: 5 ft 11 in and 7 ft 7 in
Weight: 6.6 -13.9 lb
The Bald Eagle, primarily found in Canada and Alaska, is instantly identifiable by its white head, dark brown body, yellow beak, and a piercing cry. Its sharp, orange-yellow eyes aid in efficient night hunting.
Predominantly residing in North America, occasionally venturing into Asia and Europe, it thrives near water bodies. It perches atop trees, providing a bird’s-eye view of its prey. It feeds on fish, carrion, small mammals like rabbits and squirrels, and reptiles. Hunting involves a swift downward swoop to seize the prey, carrying it back to the nest.
Bald Eagles are monogamous, forming lifelong pairings. They construct vast nests from sticks, lined with moss or grasses. They typically lay 1-3 eggs annually, which hatch around 35 days later. The fledglings leave the nest roughly 6 weeks after hatching, but continue to rely on their parents for nourishment for a further 5-6 months, until they become proficient hunters.
Turkey Vulture (Cathartes aura)
Turkey Vulture Sound
Scientific Name: Cathartes aura
Length: 24–32 in
Wingspan: 63–72 in
Weight: 1.8 to 5.3 lb

Turkey vultures live in the Americas, Europe, Africa, and Asia. They can be found in deserts, grasslands, forests and swamps. Turkey vultures are found throughout North America and parts of Central America and South America. In the U.S., they can be found across the country, but most commonly in the southwest region.
Turkey vultures eat carrion—dead animals’ remains such as dead deer, sheep, cows, horses and other large mammals that have been killed by other predators, such as coyotes or foxes. They do not hunt live prey.
The Black Vulture (Coragyps atratus)
Black Vulture Sound
Scientific Name: Coragyps atratus
Length: 22–29 in
Wingspan: 52–66 in
Weight: 3.5 to 6.6 lb
The Black Vulture is easily recognizable by their black plumage, short, square tail, and their bald black head.
These birds are scavengers and play a vital role in the ecosystem by feeding primarily on carrion (dead animals). They are known to occasionally kill smaller, weakened animals, but such behavior is not the norm. Black Vultures locate food using their excellent sense of sight and by following other vultures.
Unlike most birds, Black Vultures are not known to build traditional nests. Instead, they lay their eggs in sheltered areas like hollow trees, abandoned buildings, or thickets. They typically lay two eggs, and both parents will incubate and care for the chicks.
Black Vultures are social birds that are often seen in large groups. They roost together in large numbers and are known to even forage in groups. They can often be seen soaring on thermals during the day, hardly flapping their wings, while looking for food.
Red-tailed Hawk (Buteo jamaicensis)
The Red-tailed Hawk is a large bird of prey that is commonly found across North America. This species is part of the genus Buteo, which is often referred to as the “true hawks,” and includes more than two dozen species of raptors.
Red-tailed Hawks have a robust size, ranging from 18 to 26 inches in length and sporting a wingspan that can exceed 4 feet. They have a broad, rounded set of wings and a short, wide red tail. This species is most easily recognized by its rich, rust-colored tail, which gives it its common name. However, juvenile hawks might not yet have this distinctive feature.
Their feathers are generally dark brown on their dorsal side (back) with a lighter, often speckled, ventral side (front). The intensity and pattern of their plumage can vary significantly based on their age and geographic location, as there are about 14 recognized subspecies of Red-tailed Hawks.
As for their diet, Red-tailed Hawks are carnivores and have a broad diet that includes rodents, ground rabbits, reptiles, and other birds. They are skilled hunters that typically sit on high perches and use their keen eyesight to spot potential prey. Once they have identified a target, they swoop down to capture it with their powerful talons.
Red-tailed Hawks mate for life and build nests high off the ground, often in tall trees or on cliff edges. Their nests are made of sticks and can be quite large. They typically lay 1-3 eggs per year, which are incubated by both parents.

Sharp-shinned Hawk (Accipiter striatus)
The adult bird is brown on top and white underneath, with a dark brown band across its chest. It has short, rounded wings and a long tail that makes it look larger than it actually is. Adult sharp shinned hawks have black eyes, which are surrounded by white feathers. The female Sharp-shinned Hawk is browner than the male, who has darker brown markings on his back.
Sharp-shinned Hawks prefer open country for their habitat, including fields and meadows where they can hunt for mice and other small animals. They can be found throughout the United States but are most common in the east.
Sharp-shinned Hawks eat mostly small birds, such as sparrows and warblers, as well as small mammals such as mice and gophers. They catch prey by surprise using their incredible speed and agility, diving out of the sky at speeds up to 200 mph.
Sharp-shinned Hawks have an unusual hunting style for hawks—they prefer to catch their prey from perches above trees or telephone wires, rather than swooping down from above like most other hawks do and can often be seen hunting near bird feeders.
Cooper’s Hawk (Accipiter cooperii)
The Cooper’s Hawk is a medium-sized bird of prey native to North America. Known for its agility and speed, it is part of the Accipitridae hawk species, which also includes other hawks, eagles, and kites.

The Cooper’s Hawk is a skilled predator, primarily hunting birds and small mammals. They are adept at hunting in both dense forests and open areas, often catching prey mid-air in high-speed pursuits. They have also been known to visit the backyard bird feeder, not for the seed, but to prey on the smaller birds that gather there.
Cooper’s Hawks often build nests in dense tree canopies where they are well concealed. The female usually lays 3 to 5 eggs, and both parents share incubation duties. The young hawks fledge after about a month but will stay close to the nest, relying on their parents for food as they learn to hunt.
Red-shouldered Hawk (Buteo lineatus)
The red-shouldered hawk are medium sized birds of prey, part of the buteo hawks family. It can be distinguished from other hawks by its reddish iris and pale legs.
The adult has rusty red upperparts, white underparts, a black chin and throat, and a reddish brown stripe over each eye, reddish brown heads and a strongly banded tail. The tail is reddish brown with two paler bands across it and they have white checkered wings. Juveniles are brown with dark barring and have pale fringes on the feathers of their wings.
Red-shouldered hawks nest in trees, though they also inhabit manmade structures including barns, bridges, and buildings. They prefer wooded areas with an open canopy but will use other places as well for nesting such as shrubs and hedges if needed.
The red-shouldered hawk’s diet – they eat small mammals such as ground squirrels, rabbits, voles, mice and rats. They also eat birds such as quail, pigeons and doves; reptiles including snakes; amphibians; fish; crustaceans; insects; and carrion (dead animals).
Broad-winged Hawk (Buteo platypterus)
Broad-winged Hawk Sound
The Broad-winged Hawk holds a commanding presence as one of the largest hawks in the world, known for its broad wings. Its formidable size is a testament to its prowess as a bird of prey, effortlessly navigating the open skies in search of food.

In the winter they migrate south to warmer climates. They prefer to live in dense coniferous forest with large trees but will occasionally nest in shrubs or other vegetation that can protect them from predators.
The Northern Saw-whet Owl eats mice and voles (small rodents), small birds, frogs, salamanders, moles and shrews, but unlike most owls they chop their prey up and spread over a few meals. They will also eat insects like beetles and grasshoppers if they are available. It hunts from a perch at night using its excellent hearing to locate prey items within about 30 feet (9 meters) of its nest.
These owls nest in tree cavities usually located close to water sources such as lakes or rivers where they can find their food source (insects). They lay 2-4 eggs at one time which incubate for about 30 days before hatching.
Short-eared Owl (Asio flammeus)
Short-eared Owl Sound
Scientific Name: Asio flammeus
Length: 13–17 in
Wingspan: 33 to 43 in
