Wild Animal Rehabilitation — Standards and Outcomes

Wildlife rehabilitation treats injured and orphaned wild animals with the goal of returning them to their natural habitat, raising important welfare questions about methods and outcomes.

Key Facts

The US has approximately 4,000 licensed wildlife rehabilitators treating millions of animals annually
Release success rates vary enormously by species — songbirds 50-60%, raptors 40-50%, deer 60-70%
Animals that cannot be released face the welfare dilemma of permanent captivity or euthanasia
Human imprinting in rehabilitation can prevent release and requires careful management
The International Wildlife Rehabilitation Council sets minimum standards for rehabilitators

Welfare Considerations

Wildlife rehabilitation welfare involves complex judgments at every stage. Treatment decisions must balance the welfare cost of the treatment process against the benefit of recovery and potential release. Some species suffer more in captivity than the welfare benefit of treatment justifies. Imprinting on humans during rearing creates animals that cannot survive in the wild. Permanent placement for non-releasable animals requires high-quality environments that meet species needs. Good rehabilitation minimizes human contact, maintains appropriate fear responses, and sets welfare-informed release criteria rather than treating release as the always-correct outcome.

What You Can Do

If you find injured wildlife, contact a licensed rehabilitator before attempting care
Support local wildlife rehabilitation centers with donations of time, food, and funds
Never attempt to hand-raise wild animals without professional guidance — imprinting prevents release
Advocate for adequate state and federal funding for wildlife rehabilitation licensing and training
Support research into rehabilitation outcomes to improve release success rates
