Being a wildlife biologist is a wonderful career goal, one which will enrich you as a person while contributing to environmental stewardship. You don't say where you now are in your education. If you are in high school, I recommend that you volunteer or get a part time job at a local zoo (if you have one), veterinary clinic, or even a pet store. Start building a resume early. Read books on caring for pets and do pet care for people in your neighborhood. Join an organization like your state herpetological society or local birding club to establish a record of your interest in wildlife. Volunteer for conservation efforts in your community. Observe animal behavior - pets and wildlife and keep a journal. When it is time to apply to college, look for colleges with good zoology departments. You will likely need to earn at least a masters degree to get a good job with a state or federal agency or an NGO like the Chesapeake Bay Foundation. There are many NGO's that hire wildlife biologists. Good luck! My own son who just turned 16 has the exact same career interest and is doing these things too.
