I have seen markhor in the United States collections referred to as Turkmenian markhor, Tadjik Markhor, and Bukharan markhor. It is my understanding that this is the same subspecies, Capra falconeri heptneri. Are the markhor found here in the United States of America only of this subspecies...
A male Turkmenian Markhor (Capra falconeri jerdoni). They were kept on the upper level of the Mappin Terraces. There is a story of one of these animals walking along the top of the perimiter fence (like a tigtrope walker), turning around and returning to the enclosure without putting a foot wrong.
