One of the two camels kept at the Yerevan Zoo has died, EcoNews.am reported. The exact cause of the animal’s death is still unknown.

The two Bactrian camels (Camelus bactrianus) are one of the oldest “residents” of the zoo. Currently, the Bactrian camel is listed as Critically Endangered on the IUCN Red List of Threatened Species and is restricted to two Asian countries – China and Mongolia. A few of them can be found in Russia as well.

Over the past two months, several other animals and birds, including pigs, a pheasant and a lizard, also died at the Yerevan Zoo, but no respective information is available on the official website of the zoo.
