5 Types of Hawks in the US: Which Species are Most Endangered

Types of Hawks in the US

Hawks are birds of prey found under the Accipitridae family, one of the three families under Accipitriformes. Of the 200-hawk species in the world, around 19 of them are in America.

Hawks are a crucial part of the ecosystem as they help regulate the population of small rodents, like voles, squirrels, gophers, mice, and rabbits. If these herbivores’ numbers increase, they can threaten the ecosystem by damaging crops and property and bringing diseases.

There are about 19 types of hawks in the United States, but some are more common than others. The common ones are the types you see around in almost any habitat.

Among these common ones includes the Red-tailed, Cooper’s, Broad-winged, Sharp-shinned, and Ferruginous hawks. All these birds can be observed in every state in any environment, from parks to urban centers. The physical characteristics of hawks differ with species and types.

The article covers five common types of hawks in the United States and explains their physical descriptions, habits, diet, mating, and more interesting facts. Therefore, read on.

Red-Tailed Hawk

Red-tailed hawk is one of the most common species of hawks found in the US. They hold the following characteristics for different aspects.

Red-Tailed Hawk

Physical Characteristics of Red-Tailed Hawk

Red-tailed hawks, as their name tells, have cinnamon red tail feathers that are pale from below. They come in a variety of colors from white to black and also bear different styles of markings. Therefore, other than the red tail, using these other features as hawk identification markers have proven challenging.

This bird of prey has a wingspan of four feet which is handy when soaring. The female can have up to 60 inches wingspan. Their height is between 18 and 24 inches for male and 19 to 26 inches for females, measured from head to tail.  They can achieve speeds of up to 120 mph while diving.

An adult male Red-tailed hawk can weigh up to three pounds while the female gets up to 3.8 pounds. The juveniles have yellow eyes which turn to brown as they age. They have curved beaks with a sharp tip.

Physical Characteristics of Red-Tailed Hawk

Habitats and Range of Red-Tailed Hawk

Red-tailed hawks are widely spread through the states and locations. They are in open country, woodlands, plains, prairie grooves, and mountains. They can be found in any habitat with high perches from where they can scan the prey.

There are also more populations of these hawks in different regions of the US. They are in most states and well adapted to the environments, including the urban centers. 

Habitats and Range of Red-Tailed Hawk

Diet Habit of Red-Tailed Hawk

Red-tails are predators and hunt on small rodents, but sometimes eat birds and reptiles, like snakes. Their diet varies with location and season, whereas those in areas with prey scarcity hunt more birds and reptiles. However, small mammals are the most preferred diet of hawks, including red-tailed hawks.

Their hunting strategy includes observing from a high perch, then diving and capturing prey with their sharp talons. Red-tail hawks also soar over hunting grounds and use their excellent sight to spot prey animals and swoop down and catch them.  

Diet Habit of Red-Tailed Hawk

Mating and Nesting Habits of Red-Tailed Hawk

Red-tailed hawks reach breeding age when they are three years old. Their breeding season is spring, in March and May. These birds engage in aerial displays, make shrill cries, and preen each other during courtship which is among the many mating habits of hawks.

The birds then build a nest on tall trees using sticks, twigs, and barks. The clutch size is between 1-5 eggs. The breeding pair stays with their babies for at least 42 days after hatching, after which they become independent.

Diet and Hunting Strategies of Ferruginous Hawk

Ferruginous hawks feed on various types of prey, including reptiles, insects, and mostly small mammals. Some of their prey mammals include pocket gophers, Kangaroo rats, jackrabbits, and ground squirrels. They also feast on snakes and large insects like grasshoppers and crickets.

Since the hunting habits of hawks vary, the ferruginous hawk sometimes hunts by standing on the ground and running at prey. They also perch on nearby trees or posts where they dive on prey and catch it. However, the bird may also soar and scan for prey animals from high in the sky.

Diet and Hunting Strategies of Ferruginous Hawk

Mating and Nesting Habit of Ferruginous Hawk

Ferruginous hawks’ breeding season is in between March and April when they return from the wintering grounds. These birds are territorial and build their nest far from another breeding pair. The distance can be at least half a mile apart, but an ideal distance is at least a mile apart.

They build their nests on trees, hillsides, rocky outcrops, and also on the ground. The building materials include grasses, bones, horse dung, twigs, and roots, and both males and females participate in building. The female lays about four eggs and incubates them for about 25 days.

Endangered Hawks in the US

Despite the Hawks being on the top of the food chain, a lot goes on in their lives, and sometimes their survival is threatened. Studies show that twenty of the 200 species of hawks in the world are endangered.

Endangered Hawks in the US

Some of the common threats to hawk survival in the United States include;

1. Deforestation

Most times, the loss of habitats where they usually breed and hunt is a reason for their population decrease. Forests are the common habitats of hawks, which is where they hunt and build nests. Human activities, like deforestation and urbanization, are among the reasons. While the nesting habits of hawks can change and adapt to the urban environment, most species cannot. 

2. Pesticide poisoning 

Before 1972, DDT used as a pesticide led to a decrease in the hawk population before being banned. A study on DDT effects on eggs shows that the eggshells get significantly thinner and lighter if a bird ingests DDT.

3. Poaching

Hunting by poachers who use these predator birds as trophies has increased the threat to their survival. Also farmers shooting, trapping, or killing hawks while protecting their domestic fowl, has led to endangerment.

4. Exposed power lines

Electrocution through exposed power lines is among the contributing factors to hawks’ population decrease. While the number of deaths cannot lead to the endangerment it’s a threat to their survival. Around 417 raptors were determined to have died from electrocution between 2000 and 2015.

Endangered Hawk Species In the US

Following are some endangered hawks in the US. Some are listed as endangered in their state rather than the whole country. However, since less is known of their population elsewhere, they require conservation efforts.

Hawaiian Hawk
  1. Red-shouldered hawks – It’s believed fewer than 200 pairs breed in New Jersey.
  2. Hawaiian Hawk – According to IUCN Red List, the Hawaiian Hawk is rated as near threatened according to a 2016 report. 

Conservation Efforts for The Endangered Species

The United States government has done a lot in conservation efforts for endangered hawks and other animals. First off, they raised a DDT ban, which could have wiped out populations of birds and mammals.

Also, federal protection minimizes occasions where hawks are shot by farmers and poachers. Coating the power lines is another conservation effort, which reduces death and injuries through electrocution. 

Conclusion

After reading the article you should have a better understanding of the types of hawks in the United States. Since under each bird, their physical descriptions, habitats, diet, and mating habits are included, you get a better comprehension.

Hawks are crucial to the ecosystem as they keep the number of herbivores in check. Red-tailed, Cooper’s, Broad-winged, Sharp-shinned, and Ferruginous hawks are among the common types in the United States. Human activities, like deforestation and urbanization, have led to the endangerment of some species.

Learning and understanding different types of hawks is vital for research. This knowledge helps you understand various hawks and their environment, including their preferred habitats.
