"Most wildlife rehabilitators get started by volunteering with their local zoo, animal shelter or city animal control department, where their charges may range from migratory birds, to more exotic animals (in the case of zoos).
People who enter the field of wildlife rehabilitation do it purely for the fact that they can make a difference in the lives of the animals they work with. The pay, if there is any, can be low to moderate, and most of this work is done on a volunteer basis or to supplement other steady income.
Salary should not be the motivating factor when considering becoming a wildlife rehabber, as often the pay, if any, is a stipend or minimum wage."
