Two white tigers appeared for the first time in the Sofia Zoo, which reopened after being closed for two months due to the Corona virus.
The chief park guard, Radko Sirtov, said the tiger Chiava and his sister Narcisse, two genetically modified species of the well-known Bangladeshi orange tigers, arrived from Hungary in January.
Sertov said that people can see the two tigers when they leave the barns only under the measures to limit the spread of the virus.
He now added about 150 kg, but the young male tiger can weigh up to 200 kg.
There are less than 4000 tigers in the wild, down from a hundred thousand at the beginning of the twentieth century. This is due to illegal hunting, logging and overfishing of their prey.
The World Wildlife Fund says there are about 2,500 Bengal tigers in the wild, mostly in India.
