The Red-tailed Hawk is one of North America’s most widespread raptors, inhabiting a diverse range of environments from woodlands and deserts to urban areas and grasslands. This bird is easily recognizable by its striking reddish-brown tail, which contrasts sharply with its dark brown back and pale underparts.
The Red-tailed Hawk’s broad, rounded wings and short, wide tail make it a master of soaring flight. Often seen perched high in trees or on telephone poles, they survey their surroundings with keen eyesight, ready to swoop down with impressive speed.
Red-tailed Hawks are meticulous nest builders, often choosing high, secluded spots such as tall trees or cliff ledges to construct their large, sturdy nests. Made from sticks and lined with softer materials like bark, leaves, and grass, these nests provide a safe haven for their eggs and young.
Both males and females participate in building and maintaining the nest. During the breeding season, they fiercely defend their territory from intruders, showcasing their protective instincts. The nests are often reused and added to each year, growing larger and more intricate over time.
The Red-tailed Hawk’s diet is diverse and adaptable, reflecting its status as a top predator. These hawks primarily hunt small mammals such as rabbits, squirrels, and rodents, but they are also known to prey on birds, reptiles, and insects.
Their keen eyesight allows them to spot prey from great distances, and they use their powerful talons to capture and kill. Perched high above the ground, they patiently scan for movement before swooping down in a swift, controlled dive to seize their target.
Red-tailed Hawks have benefited from significant conservation efforts over the years, largely due to their adaptability and wide range. Historically, they faced threats from habitat destruction, hunting, and pesticide use.
However, legal protections and habitat conservation initiatives have helped their populations remain stable. The Red-tailed Hawk is now a familiar sight across North America, often seen soaring along highways or perched on roadside poles.

The Sharp-shinned Hawk, the smallest hawk in North America, is a nimble and agile bird of prey. It is primarily found in dense forests and wooded areas across the continent, from southern Canada to Central America.
This hawk features short, rounded wings and a long, narrow tail that aid in its swift, darting flight through trees. Its plumage is slate gray on the back with a lighter, finely barred underbelly. The Sharp-shinned Hawk has striking red eyes and long, slender legs, giving it a fierce appearance despite its small size.
These small but fierce raptors select coniferous or mixed forests for their nesting sites, often constructing their nests high in the trees. The nests are made of twigs and lined with softer materials like bark, leaves, and feathers. Both the male and female contribute to building the nest, which is well-hidden among the foliage. The female typically lays 3 to 8 eggs, and both parents are involved in incubating the eggs and feeding the young, showcasing their strong parental instincts.
The Sharp-shinned Hawk is a specialist predator, primarily hunting small birds. Agile and quick, these hawks use their short, rounded wings and long tails to maneuver through dense forests at high speeds, ambushing their prey with precision. They often wait in ambush near bird feeders or dense thickets, where small birds gather. In addition to birds, they occasionally prey on small mammals, insects, and reptiles. Their hunting technique involves a sudden, rapid chase, capturing their prey with swift, powerful talons.
Sharp-shinned Hawks have experienced fluctuations in their populations due to habitat loss and pesticide use, particularly during the mid-20th century. Conservation efforts have focused on reducing pesticide use and protecting forest habitats to support their populations. Legal protections and increased awareness have contributed to a gradual recovery of their numbers.
These hawks are now commonly seen in both rural and suburban areas, reflecting the success of conservation initiatives. Ongoing efforts aim to monitor populations and ensure the preservation of their forest habitats, supporting the continued resilience of this agile predator.
4. Rough-Legged Hawk
- Scientific name: Buteo lagopus
- Life span: Up to 15 years
- Size: 18-20 in (46-51 cm)
- Weight: 1.5-3.25 lbs (680-1470g)
- Wingspan: 52-54 inches (132-137 cm)
- Status: Least Concern
- State status: Migratory and common
The Rough-legged Hawk is a striking raptor, easily identified by its feathered legs, which provide insulation in its Arctic breeding grounds. During the winter, it migrates to the open fields and prairies of the lower 48 states.
This hawk has a distinctive plumage, with a dark belly band and a variety of color morphs, ranging from pale to dark. Its wings are long and broad, with a characteristic white tail base and dark terminal band.
Rough-legged Hawks are unique among hawks for their Arctic breeding habits. They build their nests on cliffs, rocky outcrops, or in low shrubs in the tundra regions of Alaska and northern Canada.
These nests are constructed from sticks, lined with softer materials such as moss, grass, and feathers to provide insulation against the cold. Both males and females are involved in nest building and maintenance. The female typically lays 2 to 7 eggs, and both parents share the responsibilities of incubation and feeding the young, showcasing their cooperative breeding behavior.
The diet of Rough-legged Hawks is primarily composed of small mammals, particularly lemmings and voles, which are abundant in their Arctic breeding grounds. During the winter, when they migrate to southern regions, they adapt their diet to include other small mammals and birds.
They are skilled hunters, often seen hovering over open fields and tundra, using their keen eyesight to spot prey from a distance. Their long wings and feathered legs are well-adapted for hovering and insulation against cold temperatures, making them efficient hunters in harsh environments.
Rough-legged Hawks have generally stable populations, but they are sensitive to changes in their Arctic breeding habitats. Conservation efforts have focused on monitoring their populations and protecting critical habitats from development and climate change impacts.
These efforts include international cooperation, as their migratory patterns span vast regions. Historical conservation measures have helped maintain their numbers, but ongoing initiatives are necessary to address new challenges.
5. Osprey
- Scientific name: Pandion haliaetus
- Life span: Up to 10 years
- Size: 21-26 inches (54-66 cm)
- Weight: 2-4.6 lbs (0.9-2.1 kg)
- Wingspan: 5-6 feet (1.5-1.8 meters)
- Status: Least Concern
- State status: Breeding and rare
The Osprey, also known as the sea hawk, is a fish-eating bird of prey found near coastlines, rivers, and large lakes around the world. It has a distinctive appearance with dark brown upperparts and contrasting white underparts.
The Osprey’s head is white with a striking dark eye stripe. Its wings are long and narrow, with a unique M-shape when seen in flight. Known for its dramatic diving behavior, the Osprey plunges feet-first into water to catch fish.
Ospreys are remarkable for their nesting behavior, often building large, conspicuous nests near water bodies such as lakes, rivers, and coastlines. These nests are constructed from sticks and lined with softer materials like seaweed, grass, and bark.
Ospreys frequently reuse and add to their nests each year, resulting in substantial structures that can last for many years. Both the male and female participate in building the nest. The female typically lays 2 to 4 eggs, and both parents are involved in incubation and feeding the young.
Ospreys have a highly specialized diet, feeding almost exclusively on fish. They are expert anglers, using their keen eyesight to spot fish from above and then diving feet-first into the water to catch them. Their reversible outer toes and barbed pads on their feet help them grasp slippery prey. This diet requires Ospreys to live near water, where they can find an abundant supply of fish.
Ospreys faced significant population declines in the mid-20th century due to pesticide use, particularly DDT, which caused eggshell thinning and reproductive failures. Conservation efforts, including banning harmful pesticides, protecting nesting sites, and installing artificial nesting platforms, have led to a remarkable recovery. Ospreys are now a conservation success story, with populations rebounding across much of their range.
