The Avian and Exotic Animal Clinic provides care for injured native wildlife that have been found by the public outdoors, for example, hawks and owls, songbirds and mammals.  While we do not charge for this care, donations are greatly appreciated, and can include towels, heating pads, and appropriate foods (call for details) in addition to simple monetary contributions.
We are sorry, but due to the volume of calls, we do not take after hours emergency calls for wildlife.  After hours calls are directed to state and federally licensed wildlife rehabilitators who are trained to provide emergency care, and will transport them to the clinic for medical attention (see below).
Please be advised that it is illegal to capture and keep native Indiana wildlife for any reason, other than rescue and transportation to licensed wildlife rehabilitators.  In general, most wildlife do not make good pets, and some can cause severe injury to would-be rescuers. 
A wonderful website for information on what to do with injured or orphaned birds while you are waiting for response from a licensed rehabilitator is: http://home.mindspring.com/~chris.hatton/
Injured mammals should be carefully trapped into a container such as a box, or in case of larger wildlife a large cardboard box or trash can.  Be careful not to directly handle any injured mammal during a rescue attempt.  Orphaned young mammals should be provided with a gentle heat source, such as hot water bottles or a heating pad on low, until they can be turned over to the rehabilitator.
Injured wildlife can be dropped off any time at the clinic during regular clinic hours.
