Wildlife rehabilitation is an important welfare intervention but inappropriate rescue of animals that do not need help can cause harm rather than benefit.
Animals incorrectly assumed to need rescue and brought to rehabilitators experience unnecessary capture stress, separation from parents, and potentially inappropriate feeding that causes lasting harm. Fledgling birds picked up by well-meaning members of the public and removed from their territory often die from stress or imprinting issues. Young rabbits and deer separated from mothers that were present but hidden die from lack of appropriate milk. True casualties including animals that are clearly injured, unresponsive, or in immediate danger do benefit from rehabilitation intervention when handled by trained professionals.
