Wildlife rehabilitation is the treatment and care of injured, orphaned, or sick wild animals so that they can be released back to the wild.
Rehabilitation begins when an animal is found and reported to a wildlife rehabilitator, or seized from the illegal wildlife trade or a poacher. The rehabilitator will examine the animal to determine the extent of the injury and the probability of successful rehabilitation. If it appears that the animal can make a sufficient recovery to be able to return to the wild, the animal will be fed, nurtured, provided safe temporary housing, and medically treated as necessary.
Animals that cannot be rehabilitated are usually euthanized humanely, although animals are occasionally placed at facilities appropriately licensed for educational exhibit or brought into appropriate lifetime care in a wildlife rescue center.
A non-releasable animal may sometimes be kept by the rehabilitator (under separate permit) as a surrogate parent for orphaned or injured young wildlife.
