Ironic thing is, I am a researcher, but I am the keeper for my subjects, I have taken over their care and do the feeding and cleaning! That is rare though, I am a very hands on person and love looking after the primates.
Zookeeping is not the profession for someone looking to get rich! Dedicated keepers are, however, some of the happiest people I've ever known. Many seem to have an inner peace when working with or talking about their animals. I know I'm darn near giddy when I get to spend time with my kangaroos instead of the piles of paperwork on my desk!
