The foals were born at the end of last year and have been raised mainly in the heated stables of Tarzan's Path, but with the arrival of good weather, the public will be able to see the "horses in their pyjamas".
The fillies are currently in a separate outdoor pen and are gradually getting acquainted with the other residents of the multi-acre black continent ungulate enclosure, including Rothschild's giraffe, black-horned eagle owl and Addax's antelope.
Their diet consists mainly of mother's milk for the first 6-7 months, but they also start to taste fibre feed at 30-40 days of age.
The Grévy's zebra (Equus grevyi) is the largest zebra species and the largest wild horse species. It is easily distinguishable from other zebra species, such as the lowland and mountain zebra, by its white belly, the white band along the spine and its much larger ears. The species is named after the 19th-century French president Jules Grévy, who received a specimen as a gift from Abyssinia.
The wild population has declined dramatically in recent decades, with only 2,000 individuals remaining in southern Ethiopia and Kenya. This is mainly due to habitat loss and hunting, which is why it is important to keep them in closed housing conditions. The Nyíregyháza Zoo also received breeding animals under the European Endangered Species Programme.
