How does stress impact rehabilitated wildlife?

Stress significantly impacts rehabilitated wildlife, primarily by inhibiting their recovery and potentially leading to further health complications. When wild animals experience stress, whether it stems from captivity, human interaction, or environmental changes, their physiological responses can compromise their immune systems. This makes them more susceptible to illness and slows down the healing process, which is particularly detrimental for animals that are already injured or sick.

Stress can trigger a fight-or-flight response that releases hormones such as cortisol, which, in elevated levels over prolonged periods, can hinder normal bodily functions. It can affect the animal's ability to eat, sleep, and perform necessary behaviors for rehabilitation. The cumulative effect of stress may result in increased vulnerability to diseases, prolonged recovery times, and ultimately a decreased chance of successful reintroduction into the wild. Understanding the implications of stress on rehabilitated wildlife is crucial for wildlife rehabilitators to foster a calm environment that supports recovery and successful reintegration into their natural habitats.
