New Jersey has a number of volunteers, known as wildlife rehabilitators, who can answer your questions and if necessary, properly care for sick, injured and orphaned wildlife.
These volunteers are licensed by the NJ DEP Division of Fish and Wildlife and donate their time and do not charge for their services. They treat and care for wild animals until they can, hopefully, be released back into the wild.
