What would be better: Zoology or Wildlife Biology?

These two majors may overlap quite a bit depending on what university you go to. You can work outdoors studying wildlife with a major in either of these..but like I said..you should check out what actual cles each has you taking and pick the major that concentrates more on training you to work in the field. Cles such as ecology, ornithology, herpetology, mammalogy, entomology, invert and vertebrate zoology, wildlife management, etc. will help you build field skills. Once out of school, you can apply for jobs that interest you most..you can go for field work or work in a zoo or lab setting..it is up to you to shape your career.
