“A large part of our research is studying reproductive cycle hormones; one way that we do that is by collecting and analyzing urine samples. To obtain the samples, keeper Tara Buk has trained our young Persian onagers to urinate on command, just like their mothers do. Training this behavior takes an exceptional amount of patience and positive reinforcement, but Tara’s hard work has paid off. Our ability to quickly and consistently collect urine has greatly expanded the Smithsonian Conservation Biology Institute’s research potential. In addition, she’s acclimated our onager and Hartmann’s zebra herds to chute systems and scales, thereby enhancing preventative medical procedures and improving animal health and quality of life.” – Dolores Reed, supervisory biologist at SCBI #NZKW2017 @fonznationalzoo
