Did you know that about 1,000,000 Cooper’s Hawks live in North America? These birds are not just common; they are also very interesting. They can be found in many places, from city backyards to thick forests.
The Cooper’s Hawk breeds from southern Canada to northern Mexico. This article will show you how amazing these birds are. We’ll explore their behaviors and where they live.
Introduction to Cooper’s Hawk
Cooper’s Hawks are skilled hunters in the woods. They are known for their flying skills and how well they adapt. They have an upright posture and a long tail, helping them move through dense forests.
The adult Cooper’s Hawk has bluish-gray feathers on top, a black cap, and bright red eyes. This makes them very striking. Young Cooper’s Hawks have brown feathers on top and white on the bottom with strong brown streaks.
Cooper’s Hawks are bigger than Sharp-shinned Hawks and as big as crows. Female Cooper’s Hawks are about 20% heavier than males. They can be told apart by their dark caps and gray napes.
Those in Western North America are about 20% smaller than those in the East. They fly in a flap-flap-glide pattern, showing their efficiency. Even in open areas, they flap less, which is impressive.
These hawks eat smaller birds, which is most of their diet. They can be seen near backyard feeders, showing their adaptability. They have a long, rounded tail with some having thick bands, making them stand out.
Physical Characteristics of the Cooper’s Hawk
The cooper’s hawk has unique physical traits that make it stand out. Adults have bluish-black backs and pale underparts with reddish barring. Their *red eyes* are a key feature, unlike the *yellow eyes* of young birds. The sharp black cap on adults is clear against the gray nape, helping with identification.
Sexual dimorphism is evident in cooper’s hawks. Females are larger, measuring 16 to 20 inches, while males are 14 to 16 inches. Their wingspan is 28 to 36 inches, with short, rounded wings and long, rounded tails. This shape helps them move well in wooded areas.
Juvenile hawks look different, with brown upperparts and white underparts and brown streaking. As they grow, their appearance changes, showing their age and gender. Young birds have a larger head that sticks out beyond their wings, making them easier to spot.
Egg incubation lasts 30 to 33 days, with 3 to 5 eggs laid. Young hawks start climbing at four weeks and make short flights soon after. Parental care, including feeding, lasts up to seven weeks after hatching.
Cooper’s Hawk Habitat
Cooper’s Hawks are very adaptable birds. They live in many different places. Their favorite places are mixed and deciduous forests. These forests give them the cover they need to hunt well.
They also like open woodlands, small woodlots, and areas near rivers. Even in cities and suburbs, they can be found. There, they hunt smaller birds.
These hawks have a special way of living. They breed once a year, usually when they are two years old. They build their nests in tall trees, often in forests.
Their nests are about 61-71 cm wide. They can have 3 to 5 eggs. These eggs hatch after 30 to 36 days.
It’s important to protect their homes. Thanks to conservation, their numbers are getting better. We need to keep their habitats safe, both in nature and in cities.
Range of the Cooper’s Hawk
The cooper’s hawk range covers a wide area from southern Canada to northern Mexico. Many stay in their spots all year, but some migrate north to avoid cold winters. They can travel as far as Central America, stopping in places like Honduras and Costa Rica.
These hawks live in many different places, thanks to their love for forests and birds. They are very good at adapting, which helps them survive and breed well. A pair usually raises two to four young, helping their numbers stay steady.
Studies show that hawks in different places are genetically different. For example, those in British Columbia and the Upper Midwest are distinct. Eastern hawks are often bigger than western ones. Fossils show they’ve been in North America for over 500,000 years.
Even with threats like losing their homes and diseases, the Cooper’s Hawk is not in danger. They are listed as Least Concern by the IUCN. Their clever hunting and ability to adapt keep them common in the skies of North America.
Behavior of the Cooper’s Hawk
Cooper’s hawks have interesting behaviors that help them survive and reproduce. They are monogamous, but males might find new partners if their mate is gone. During nesting, males bring almost all the food to the female while she sits on eggs.
Even though males are smaller, they play a big role. Their hunting skills show how stealthy and adaptable they are. They use ambush and surprise attacks to catch their prey.
Hunting Techniques
Cooper’s hawks are agile and precise hunters. They stalk their prey from hidden spots, waiting for the perfect moment to attack. After catching prey, they bring it back to their nests quickly.
This way, they ensure the female gets food while she’s busy with eggs. Their skill in dense environments helps them catch smaller birds.
Flight Patterns
Cooper’s hawks have unique flight patterns. They use a “flap-flap-glide” method to move through different habitats. This technique helps them change direction quickly while chasing prey.
Despite their agility, they can get hurt in fast chases, like in crowded areas. Young hawks often go to flowing water to bathe. This makes them ready for their first flights.
Cooper’s Hawk Diet
The cooper’s hawk diet mainly includes small to medium-sized birds, making up about 75% of their food. This variety helps them adjust to different places and times of year. They often eat robins, starlings, thrushes, jays, and mourning doves. In cities, they find plenty of food, like at backyard feeders during winter.
Prey Selection
Young cooper’s hawks mainly eat fledglings and young birds in spring and summer. As these birds grow, they need more food. So, they also hunt small mammals like chipmunks, squirrels, and sometimes young rabbits. They also eat small mammals like voles and lemmings, but these are rare because they are mostly active at night.
Hunting Strategy
Cooper’s hawks are very fast and agile when hunting. They usually look for birds at the edges of forests and open areas. They hunt best in the early morning to avoid other hawks. They even eat chickens, which is why they’re called ‘chicken hawks’. Their diet shows how flexible and adaptable they are in different environments.
| Prey Type | Percentage of Diet |
|---|---|
| Small to Medium Birds | 75% |
| Small Mammals | Less Frequent |
| Amphibians | Occasional |
| Fish | Rarely |
Cooper’s Hawk Nesting Habits
Cooper’s Hawks have interesting ways of nesting to survive. Males build nests using sticks, placing them near tree trunks for stability. They don’t reuse nests, preferring to build new ones each year, usually in March or April. In warmer areas, they start nesting in February, while colder areas wait until April.
Females lay three to four eggs, sometimes up to seven. The female incubates the eggs for 34 to 36 days. The male brings her food, about three times a day. After hatching, the chicks need 28 to 32 days to grow. Parents need 66 prey items to raise each chick to six weeks old.
Chicks start leaving the nest at 25 days for males and 28 days for females. By 31 days, they can hop and fly. Parents teach them to explore by 45 days. They become independent in two months.
Only one brood is raised each season. Despite challenges, some young hawks survive and grow up. But, only 22% to 28% make it past their first year. These details show how much care Cooper’s Hawks give to their young.
Migration Patterns of the Cooper’s Hawk
Cooper’s Hawks have amazing migration patterns, mainly seen in northern populations. As winter comes, they look for warmer places. They migrate due to food shortages and cold weather.
Many Cooper’s Hawks go to southern U.S. and Central America for the winter.
Seasonal Movements
The peak migration time for Cooper’s Hawks is October. Weather conditions play a big role in this. They travel from Canada and the northern U.S. to Central America.
They often fly in big groups and can be seen at over 1,000 sites across North America. The best times to see them are mid-morning and mid-afternoon, when they are most active.
Migration Destinations
Cooper’s Hawks like places with lots of food, like coastal areas with doves and pigeons. They also enjoy urban areas for easy food. Knowing their migration patterns helps birdwatchers plan their sightings.
Florida is a big habitat for these hawks, covering nearly 3,669,236 hectares. About 24% of this area is public land.

Cooper’s Hawk Conservation Status
The Cooper’s Hawk’s status has greatly improved from the mid-20th century. This change is thanks to a decrease in pesticide use, like DDT. Studies show a stable population in the U.S., thanks to conservation efforts.
Yet, threats remain. Habitat loss, glass collisions, and hunting are dangers. Every year, up to a billion birds die from glass collisions in the U.S. This highlights the need for more conservation.
Cooper’s Hawks breed in southern Canada and northern Mexico. They migrate far, with some reaching Panama. The female does most of the incubation, while males help with nesting.
Human changes in landscapes have helped these birds. In Texas, winter migrants add to the breeding population. This shows the species’ ability to adapt.
