Ornithologists of the DPRK have succeeded in artificial breeding of goshawk.
In 2015 researchers of the zoology institute of the State Academy of Sciences brought four 15-day-old goshawks for artificial breeding from the area of Sangdol-ri in Toksong County, South Hamgyong Province, a goshawk sanctuary. The birds of prey grew up and a female bird began to lay eggs in 2018.
Artificial breeding of predatory birds of forest is known to be very difficult worldwide.
Wild raptors like goshawk inhabiting remote mountains are so sensitive to surroundings they hardly copulate in enclosed space.
“Even though they had copulation in the cage, the female bird laid unfertilized eggs, and even at some noise or slight mistake by the breeder, it did not sit on eggs but dropped them,” recalled Kim Kyong Jun, deputy director of the zoology institute.
Researchers studied goshawk’s scope of activity and eating habit in nature and, based on this, altered the environment of the breeding place close to a natural forest while conducting research for improving nutritive conditions.
They managed to hatch the eggs of a goshawk for the first time in two years, but the chicks were dead in no more than 20 days.
The researchers solved problems related to breeding including the mixing of feed additives and nest building and succeeded in artificial breeding in three years.
A goshawk that hatched on June 1 and two others on June 7 are now able to fly.
“We have taken the first step in artificial breeding of goshawk. Our next research target is the reproduction of goshawk based on artificial hatching and insemination,” said the deputy director.
