I would be excited too !!!, Four horned antelopes (Tetracerus quadricornis) are the closest living relatives of Nilgais (Boselaphus tragocamelus) and they are the only two members of the tribe Boselephini, Four horned antelopes havent been in the United states for a very very long time, but unfortunately I have no idea what american zoo had them, I know several european zoos had them such as Berlin, Paris, Howletts, London, Port Lympne and many many others, but Four horned antelopes died out of european collections very recently, What a privelage !!!
