Bird description

Snake-eaters are often called an eagle, but these birds are not very similar in appearance. The snake-eater is a large predator with a body length of about 70 cm, a wingspan of 170 to 190 cm, the mass of adults reaches 2 kg. Females, as a rule, are slightly larger in size than males, but do not differ from the latter in color of plumage. The snake-eater’s back is gray-brown. The throat is brown. The belly is white in color with numerous dark streaks. Dark streaks are visible on the wings and tail. Young individuals are darker in color than adult birds.

Nutcracker Nutrition Features

Snake-eater nutrition is highly specialized. The diet of the bird is limited to vipers, snakes, coppers and snakes, as well as other species of snakes, in fact, due to which the species got its name. Occasionally, a snake-eater can eat lizards.

In winter, snakes are in a state of suspended animation, they do not move. Therefore, the snake-eater begins to hunt in late spring, when the earth warms up, and the snakes begin to crawl out. Most often, the predator leads hunting from noon until nightfall, that is, during the period when the snakes are most active.

The snake-eater is known as the “king of flights”: in search of prey, the bird spends a lot of time in the air. Since the view is distinguished by excellent vision, birds notice their prey at high altitude. Having noticed a snake, the snake-eater hangs in the air and then sharply falls down. During such an attack, the speed of the bird reaches 100 km / h. Approaching the snake, the krachun grabs her behind her head and finishes it off with her beak. Very often, the bird and its prey enter into a fierce battle. Having swallowed a snake, the draper flies away. On the surface of the earth, a bird rarely pursues a snake.

The most common snake-eating prey is by far, but sometimes a predator also attacks poisonous snakes, for example, an adder, a gyurza or a muzzle. Therefore, the bird always moves very clearly and quickly to avoid a fatal bite. Snake-eaters also protect the horny shields on their legs and the speed of reaction. If a snake does happen to bite a bird, this does not always end with its death. But in such cases, the snake-eater begins to hurt, and recovers very slowly.

Bird spread

The habitat of the snake-eaters includes the southeast and east of Europe, North Africa, as well as the warm regions of Asia. Some species are common in India, Indonesia, and southern China.

Today, there is a widespread decline in the population of snake-eaters. This is due to a decrease in the populations of snakes that birds feed on, their destruction by humans, as well as a reduction in suitable habitats.

Krachuns usually live in the north in woodlands, in the south in a dry forest-steppe, occasionally nest on the slopes of rocks. Birds settle in oak, linden, alder or pine massifs. Nests are built high from the ground, and at a great distance from tree trunks to ensure free approach.

Reproduction of the Serpent Eater

Migratory populations return to their breeding sites in May. Snake-eaters are monogamous birds. They build a new nest or use the old one.

The nest of a krachun is small, flat up to 95 cm in diameter, and up to 40 cm in height. An adult bird is placed in it with difficulty. A snake-eater builds a nest from thin branches, inside it is lined with green twigs, pine branches, grass, leaves, snippets of snake skins. The greenery in the nest serves as an additional disguise and covers it from the sun.

The snake-eater is a very secretive and fearful bird. At the sight of a person, she immediately flies away from the nest. Even the chicks, when strangers approach, hide and do not try to protect themselves.

Matrimonial games consist in the fact that the female and the male pursue each other, fly up, describe circles in the air and sharply fall to the ground.

Egg laying occurs at the end of May. As a rule, the female lays two eggs of white color. But the chick is born only one. The hatching period is from 40 to 45 days. The female incubates eggs, while the male feeds her.

The chick is born, covered with white fluff. Parents feed him with snakes, which the chick pulls from their throats. Then the chick swallows the snake, starting from the head. If the baby is mistaken and begins to eat the snake from the tail, his parents force him to spit it out and start over. In addition, parents often bring the nestling still alive snake so that he can learn to deal with his future prey. In total, the male and female feed the chick up to 250 snakes.

At two months, the young snake-eaters can already fly, and at the age of 80 days they leave the nest.

The snake-eater's life span reaches 10 years.
