As I said in the other thread, I've done work on the Elephant, Rhino and Primate sections at Chester Zoo.
Rhinos was my first experience. I cleaned out the Prez Horse paddock, visited Tsavo 2, visited the zebra and oryx indoor area, saw the hand-reared Sitatunga and then got to place food for the Tapir and Capybara as well as stroke the Tapirs. Also got to see inside the Asian Plains building (before it was renovated for Indian Rhino) and see the Philippine Deer up close.
Primates were next and I worked with the Ring-Tail Lemurs, Chimps and Orangs. I had to clean out the Chimp off-show areas, prepare the Chimp's food, got a full tour of the recently opened RORA and then got to hand-feed the lemurs on their island.
Elephants involved cleaning the floor, cleaning the drinking sinks, laying out hay, observing the foot treatment and going to see the elephants up close in the off-show paddocks and Upali from the cycle path.
I loved every single one of the days i've done and really hope i get to do it for my career.
