It can swoop from the sky at a lightening speed and pounce on its prey. The speed gives it so much of force that the prey often dies at the impact. This is Peregrine Falcon, the world's fastest creature. While the speed of the cheetah is 112 to 120 km per hour, the speed of this lightning bird is 300 to 390 km.
This bird is also known by different names such as Duck Hawk and Barbary Falcon.
Usually they are solitary hunters. They also migrate alone and rarely roam in pairs. However, these birds usually mate with one bird and that too for as long as they live.
The Peregrine Falcon hits the prey from above. It comes almost straight down at an impossible speed at the prey, grabs the wings with its legs and kills it with nails. The bird takes the prey to a place and first pulls out the feathers, then tears out the meat and eats it.
The falcon eats pigeons, aquatic birds, ducks, bugs, and even swan hunters. They also eat mammals such as bats, rabbits, rats, reptiles, insects, or even fish if necessary.
The bird is usually 42 cm in length. Its wings are 28 cm, beak 2.6 cm, feet 4.9 cm and tail 14.5 cm. The male and female birds are similar in appearance. However, the female bird is relatively large in size. The features are slate black head, black cheek, and black and white eyes.
Adults are blue-gray above with barred underparts and a dark head with thick sideburns. Juveniles are heavily marked with vertical streaks instead of horizontal bars on the breast. Despite considerable age-related and geographic variation, an overall steely, barred look remains.
The birds lay 3-4 eggs between March and April.
