Accipiter

These birds are slim hunters. They have short, wide wings. They also have long tails. This helps them fly through trees.

They have long legs. Their feet have sharp claws. They use these to catch food. They use a hooked beak to eat, too.

These hawks like to hide. They wait to jump out. They chase small birds and mammals. Most of them live near woods.

Females are often larger than males. They fly by flapping and gliding. This is how they move fast.

There are nine types of these hawks left. They are very clever hunters.

Accipiter is a group of birds of prey. Their name is Latin for "hawk." These birds are slim hunters. They have short, wide wings. They also have long tails. This helps them fly through trees.

They have long legs and sharp claws. They use these to catch food. They also have a hooked beak to eat. Most of these hawks live in woods or bushy areas. They often hide and wait for prey. They may catch small birds or mammals after a short chase.

When they fly, they flap their wings and then glide. This is their way of moving. In this group, females are often larger than males.

Scientists used to think there were 50 species in this group. New studies in 2024 changed this. Scientists looked at the DNA, or the tiny code inside living things. They found that many birds were not close relatives. They moved many birds to new groups. Now, there are only 9 species left in the Accipiter genus.

Accipiter is a group of birds of prey. Their name comes from a Latin word meaning "to grasp." These birds are known for being slender hunters. They have short, broad, and rounded wings. They also have very long tails. This long tail helps them move easily while flying.

These hawks have a special way of hunting. They often hide and wait to ambush their prey. They mostly hunt small birds and small mammals. After a short chase, they catch their food. Their flight is a mix of movements. They flap their wings several times and then glide. They have long legs and sharp talons for catching prey.

Scientists have studied these birds for a long time. A French zoologist named Mathurin Jacques Brisson introduced this group in 1760. The type species is the Eurasian sparrowhawk. Scientists also look at their bones to learn more. They look for a small hole called a procoracoid foramen. This hole holds a specific nerve. Most Accipiter hawks do not have this hole.

Learning about bird families can change over time. For a long time, people thought there were 50 species in this group. In 2024, a new study changed this. Scientists looked at the genetic ties between birds. They found that many birds were not close relatives. They moved many species to new groups. Now, there are only 9 species left in Accipiter.

Some birds were moved to a group called Lophospiza. This includes the Sulawesi goshawk and the Southeast Asian crested goshawk. Other small birds went to a group called Microspizias. This includes the tiny hawk from South America. The study also looked at birds like the Circus genus. These birds are closely related to Accipiter. These changes help scientists group living things correctly.

The genus *Accipiter* consists of a specific group of birds of prey. These birds belong to the larger family known as Accipitridae. They are highly specialized hunters that live in wooded or shrubby areas. Their physical design is perfect for moving through dense trees. They have slender bodies and short, broad, rounded wings. A very long tail provides them with excellent maneuverability during flight.

To catch food, these hawks use a specific hunting method called an ambush. They often hide and wait for prey to come near. Their diet mainly consists of small birds and small mammals. Once they spot a target, they engage in a short chase. Their flight pattern follows a rhythmic sequence. They perform a series of wing flaps followed by a short glide. They use long legs and sharp talons to capture prey. A sharp, hooked bill helps them with feeding.

Scientists use skeletal features to study the relationships between different bird groups. One important feature is the procoracoid foramen. This is a small hole located in the coracoid bone at the front of the bird. This hole serves to accommodate the supracoracoideus nerve. In some bird groups, this feature appears as a notch called an incisura. In other groups, the feature is completely absent. Interestingly, most studied *Accipiter* hawks lack this hole entirely. This absence is used as a diagnostic feature to identify them.

Research into these bones has revealed much about bird evolution. For example, some eagles in the genus *Aquila* show an incisura rather than a foramen. Other species in the genus *Circus* show variable results. In some *Circus* individuals, the hole might even differ between the left and right sides. Genetic research shows that *Circus* is closely related to *Accipiter*. Other birds, like *Urotriorchis macrourus*, have a well-developed procoracoid foramen. This suggests that *Urotriorchis* is separate from the *Accipiter* genus.

The history of naming these birds began with the French zoologist Mathurin Jacques Brisson. He introduced the genus *Accipiter* in 1760. The name is derived from the Latin word *accipere*, which means "to grasp." The type species for this genus is the Eurasian sparrowhawk, or *Accipiter nisus*. For a long time, scientists believed the genus contained around 50 different species. However, modern technology has changed our understanding of these birds.

Recent advances in molecular phylogenetic studies have redefined the genus. A major study published in 2024 used dense sampling to look at genetic ties. Scientists discovered that the traditional arrangement was non-monophyletic. This means the old group did not include all the descendants of a single ancestor. To fix this, species were moved to create monophyletic genera. This process left only 9 species within the *Accipiter* genus. Many species were moved to five new or resurrected genera.

Several specific groups were moved based on these genetic findings. The Southeast Asian crested goshawk and the Sulawesi goshawk moved to the genus *Lophospiza*. This group is placed in the subfamily Lophospizinae. Very small birds, like the South American tiny hawk, moved to the genus *Microspizias*. This genus belongs to the subfamily Harpaginae. Other genera like *Aerospiza*, *Tachyspiza*, and *Astur* were also established. These changes ensure that the names we use reflect the true evolutionary history of the birds.
