Chevrotains have never been wide-spread in zoos and the general public pays normanly little intrest in these species. Of the 6 species ( genus Tragulus ) 3, have some captive history : the Javan lesser, the Balabac ( or Philippine ) and the Greater mouse deer. Of these I've sofar seen only the Javan lesser and the Balabac chevrotain in life and both these species seem to be "European specialities" - are there any in US-zoos ? The 3th species with some captive-history, the Greater mouse deer is a real "American speciality". I know of only 2 Russian collections keeping the species, the rest of collections keeping it are in the USA. I found a note that the Bronx Zoo started breeding this species with a founder-group of 1 male and 2 ( or 3 ? ) females and that all other animals in the US are descedants of these 3 or 4 animals ! Can anybody give some more information about the current American population ( which zoos are keeping / breeding them and howmany ) and are the 3 or 4 start-animals still the only founders or have there been new imports I'm not aware of ?
