Picky Eaters? We’ve Got Them, Too!

Bill 100X100

Bill the lion may have a big appetite, but that doesn’t mean he’ll eat anything!  According to African Journey Area Director Amber Eagleson,  Bill’s reluctance to accept dietary change lead to his reputation as a ”picky eater”.  

“All our big cats eat a commercial ground-meat diet we purchase by the ton.  Whenever we switch meat companies, Bill is always the last to comply.  We find it ironic since he eats the largest amount of meat in the entire zoo!” states Eagleson.  

Fortunately for Bill, who consumes approximately eight pounds of meat each day, the zoo changes animal diets only a supplier cannot meet the necessary nutritional requirements.  To ease the transition to a new diet, Eagleson explains that “For most carnivores, we will mix 75% of the meat they are accustomed to with 25% of the new meat for a week and then go to 50:50 and then 25:75.  Almost always, it is no big deal for the animal.  However, Bill has given us problems almost every time.”  

What’s a zoo keeper to do?  In the case of Bill “The Picky Eater” Lion, the transition starts at 95% new to 5% old and proceeds gradually from there.

In the Indonesian Rain Forest, the term “picky eating” takes on a different definition.  Melati, Tengku, and Tara, the zoo’s Sumatran orangutans, approach their lunch very carefully.   They reach inside of pumpkins and carefully pluck out seeds one at a time.   The orangutans then shell and eat each pumpkin seed until the last one is gone.  According to Tanisha Dunbar, Area Director for the Indonesian Rainforest, Melati approaches the task so precisely that she finishes every last seed “without breaking a single one.”  

Dunbar also points out that, “Melati can peel grapes without breaking them.”  How’s that for “picky eating”?
