Behavioral and physiological responses in felids to exhibit construction

Despite the growing body of literature examining the welfare of zoo‐housed animals, little standardized work has been published on the effect of construction and environmental disruption on the physiology and behavior of affected animals. When Lincoln Park Zoo (Chicago, IL), embarked on a renovation project for its Kovler Lion House, the opportunity was taken to perform a scientific study of behavioral and physiological markers in the resident felids to determine the effect of construction and environmental disruption. Fecal samples and behavioral observations were collected on four felid species (five individuals) before, during, and after the period of construction. As a group, the average z‐score for fecal glucocorticoid metabolite concentration increased during construction relative to baseline. Levels remained elevated after construction, but trended toward baseline. All individuals demonstrated a significant decrease in the frequency of pacing and time spent visible during construction. Overall activity levels also showed a significant decrease relative to baseline measures. As zoological institutions continue to recognize the importance of habitat design, construction and renovation become inevitable. It is important to be aware of the potential consequences this can have on animals in the vicinity and to work toward minimizing negative effects. One recommendation is the availability of ample retreat and hiding space for felids during disruption to their environment. Zoo Biol. 33:267–274, 2014. © 2014 Wiley Periodicals, Inc.
