Different types of wildlife careers include being a zoologist, wildlife scientist, park ranger, nature preservation security officer, ornithologist, and marine biologist. The duties of these positions vary significantly. For example, nature preservation security staff who patrol a wildlife sanctuary directly confront poachers and help prevent them from violating the security of the park, sometimes using physical force. Zoologists study animals and their natural habitats to collect and analyze data as well as develop reports, papers, and policy recommendations for their preservation. Many wildlife positions include a mix of academic research and administrative responsibilities.
