ISIS records show 10 separate races of leopards in the world's zoos.
I'm aware that black leopards occur within some of these races, such as the Indian leopard, but is this common across most races? Are there, for instance, ever black Amur leopards? (Anyone?)
Melanism is surprisingly very common in felids; most species have had some example, at least historically. Experts consider it occurs most commonly in tropical forest species/populations such as jaguars and Malaysian leopards. However why does it occur in servals (in montain grassland) and probably not (or at least very rarely) in forest-living tigers?
I've seen that film footage of a black Serval though I've no idea why it should occur in that montane population- just chance? There are many stories of 'black' or melanistic tigers but I've never seen any evidence produced. Maybe there's just no black gene present in tigers? I have seen film of some tigers somewhere in India which had an unusual striping pattern with thicker stripes than usual -though it wasn't mentioned in the film.....
Regarding the Leopards- North Chinese and Amur must both be similar temperate races so melanism is still pretty unusual in these. Someone posted above there's another Black Amur leopard at Zurich. I also believe blacks occur less commonly in African or Indian leopards compared to S.E. Asia.ones.
In the show I saw it were said, that it was very rare fotage of the black Serval (on grasland on higher levels) and the black leopard (in mountain rainforest). But the shots didn´t look fake.
The black Amur-Leopard in Zürich I saw for myself in 1999 i think. Very impressiv. The keeper said that it was no hybrid of Leopard-Races, but for sure a Amur-Leopard.
Black leopards were also kept in a private collection in Herts (uK) - but the owner recently died and I am not sure what will happen to the collection. I believe these were not pure-bred
Black Jaguars- formerly very rare but seemingly more common in zoos nowadays. In Hanover(?) Zoo many years ago I saw a 'partiallly melanistic' Jaguar- it was spotted but with pure black across its back. I've never seen another specimen like that anywhere.
Hannover has at least 10 years no more jaguars. When were you there?
