Eastern Black Rhinoceros (Diceros bicornis michaeli)

I think it’s a black rhino.

Definitely a Black rhino .

Definitely a Eastern Black Rhino

@The Cassowary @amur leopard I have no idea how to tell the difference. The lip and forehead are supposedly the easiest way to differentiate, but with that not visible, the only way I had was the hump, which unfortunately I am quite bad at differentiating.
@Mai Thai Can you really tell the subspecies from a photo? What do you look for?

@Junklekitteb Generally, a Black rhino's horns are pointier, the hump at the back and at the shoulders is accentuated, and a few other differences but after a while, having seen both species many times, you can ID without seeing any of the 'tell-tale' features.

As regards the subspecies, Eastern black rhino is the only subspecies of Black rhino held in captivity other than South-Central black rhinos (which are only held afaik at Frankfurt Zoo in Germany). However, I'm not entirely sure what subspecies is kept in Asia so can't guarantee it is Eastern.

@amur leopard Thanks a lot. Unfortunately I believe this was the only black rhino ever held in India during my lifetime, so I don't think I’ll have much chance of ‘seeing them many times’. I’ll try looking at more photos and videos, though.

@Junklekitteb As @amur leopard said, there are only two types of Black Rhinos in captivity, the Eastern and South-Central. South-Central Black Rhinos in captivity can be found in Australia, a couple zoos in Asia, the Frankfurt Zoo in Europe, and a couple in North America. While the Eastern Black dominates the AZA and EAZA. Eastern Black Rhinos are longer, leaner, and have a more curved horn than their counterparts. South Central Black Rhinos are smaller, have straighter but a lot bigger horns, and are more wrinkled and compact. From what I can tell from this picture, one this Rhino has a very bad back problem and two it’s horn looks more curved and small to me. So jugging by the last two bits of information I can confirm that this was an Eastern Black Rhinoceros. Hope a least some of that information is helpful!
Sincerely,
Mai Thai
