I don't believe there is any news on the indian rhino, other than that they are still trying to breed them.
With the pygmy hippos, I think that the plan had been to continue to breed them. However, Abou (female) actually got quite sick and has been off exhibit for months now. Her health is improving, but I'm not sure what the breeding plans are now.
There have been some big changes with the white rhinos. Tom was brought in with plans to breed him, so I'm guessing he is valuable. The Zoo scraped the plan to bring in females from South Africa, probably due to the large expense. In the late fall though, they did receive 2 young females from Busch Gardens Tampa. Around the same time, a trade was made with a zoo in Quebec (possibly Granby), with Shaboola leaving Toronto and a 9 year old male, Tony, coming. While the females are still too young to breed, Toronto now has 4 rhinos under the age of 10, so within a few years there should be babies. The 3 new rhinos have not yet been on exhibit as they were in quaratine until just recently, but should be out in the spring.
