Gyrfalcon - a bird unusual and hardy
As already known, representatives of the falcon family are predators. The largest of them is the gyrfalcon. The bird (the photo reflects all the beauty) is very original.
Description
Krechet differs in its beautiful, mottledcoloring. Abdomen whitish with a dark shade. This is a beautiful disguise during the hatching of eggs. Large pointed wings have a gyrfalcon. The bird (the photo clearly shows all its features) has a rather unusual coloring.
Gyrfalcon is a large bird. With a body length of about 60 cm, the wingspan is up to 135 cm. This is quite impressive. Moreover, females are much larger than males. The weight of an adult reaches 2 kg. But this does not prevent the krichet after 2-3 swings of the wing to gain lightning speed, which is important during the hunt. Gyrfalcon - the bird is very hardy. He can pursue his prey about 1 km.
Externally, gyrfalcon is very similar to peregrine falcon, but the first tail is longer and less visible under the eyes.
Habitat
Krechet is a nomad bird. Prefers cooler areas of habitat. Most of them fly south in winter. But some members of this family lead a sedentary lifestyle.
Gyrfalconas are common in Asia, Europe and North America. So, in Europe, the largest number of these birds recorded in Iceland (about 2 hundred pairs).
The main habitats are river valleys, seashores, tundra. Nests gyrfalks away from man.
They migrate not only horizontally, but also vertically. So, the Central Asian kirchet changes the Alpine zone to the valley.
Feeding the Gyrfalcon
As already noted, the gyrfalcon is a bird of prey. Food for them are small birds and animals: squirrels, rabbits, ground squirrels, ducks, owls and others. The daily need for food is 200 g. Gyrfalconas are hunted either individually or in pairs, in turn forcing the prey.
They are looking for their sacrifice from a height. They hunt, like all falcons: they are caught at the top with lightning speed and are clawed at. Then they kill, breaking the neck of the victim's beak.
There is one peculiarity in gyrfalco: they never lead a hunt for their small neighbors. Moreover, the gyrfalcon do not allow this to be done by other predators, driving them from their territory.
Reproduction
Sexual maturity at the gyrfalco occurs at the age oftwo years. They choose a couple for life. The mating season begins in winter. The breeding season lasts a week. In April, with a periodicity of 3 days, the female lays one egg each. Nests are rarely built. They prefer to take strangers or nest in the rocks under a canopy. The diameter of the nest is about 1 m and in height - about 50 cm. It consists of dried grass, moss and feathers. Nests gerfalts try not to change. Known cases of nesting these birds in one place for many decades.
Cultivation of offspring
As a rule, the female lays 3-4 eggs. Chicks appear about a month later. Family responsibilities at the gyrfalcon strict separation. After the appearance of the offspring the female looks after the chicks, warming them, and the male extracts food. And before you bring prey, he plucks it away from the nest. More experienced females can sometimes leave nests and take part in hunting.
Therefore, the number of offspring of these birds varies depending on the season.
At the age of 1.5 month, chicks of gyrfalcon begin to fly and try to hunt. But far from the nest they do not fly away. The young chicks begin their independent life in the autumn.
