The hawk eagle is widespread in the tropical and subtropical zone of the eastern hemisphere: in southern Europe, Africa (except for the Sahara ), Anterior , Central and South Asia , and on the Lesser Sunda Islands . A small and sporadic hawk eagle is found in Central Asia from Turkmenistan and Tajikistan in the south to the Karatau mountains in the north [2] . Hawk eagles prefer to live in places overgrown with xerophytic shrubs [3] .
The hawk eagle feeds on mammals and medium-sized birds - hares , rabbits , gray and stone partridges , wild pigeons, ravens (jackdaws) and others. The hawk eagle catches prey mainly on the ground, but also in the air, like a falcon . Recently, hawk eagles in Western Europe have been successfully used as hunting birds [2] .
From late January to mid-April, usually 2 eggs are laid (rarely 1 or 3), which are mainly incubated by the female for 37-40 days. Young become winged at the age of 60-65 days. The relationship of partners is extremely strong, and they can remain together throughout life. Being near the nest, two partners alternately dive, perform other pieces, playing in the air [4] .
In China, the masonry of the hawk eagle was found in March, in India from November to February. Hatching lasts about 40 days, chicks become flying at the age of about 8-10 weeks. [2]
In many areas of the European range, the hawk eagle is in danger of extinction. The reason may be the extermination by man and a change in the habitat of this species, the death of birds on the wires of power lines and a decrease in the amount of basic food [4] .
