It is worth noting that contrary to the species listing on the Port Lympne website - and indeed Zootierliste, as someone (naming no names) keeps reverting the correct information because it is not mentioned on the collection website - the herd of Lechwe at Port Lympne are almost all Kafue Lechwe, with only a single individual being true Red Lechwe. These individuals are both Kafue Lechwe.
Yeah, until recently there were entries for both taxa but as noted above, someone keeps deleting the entry for Kafue Lechwe I try to keep on top of that kind of thing but it sometimes slips past!
