“To have 3 of them that have reached the age of 50 is just extraordinary,” described Katie Pilgram-Kloppe, zoological supervisor of the River’s Edge at the zoo.

Donna was receiving the pedicure simply because foot treatment is important for elephants, particularly as they age. Some of the older female elephants at the zoo, Pilgram-Kloppe claimed, can weigh around 8,000 lbs ..

Preserving the 3 geriatric elephants nutritious is essential due to the fact they participate in a critical job among the the 9 full elephants that are living there, primarily the more youthful kinds.

“They are there to help sort of instruct them what it truly is like to dwell in a dominant woman culture,” Pilgram-Kloppe mentioned.

Mainly, the feminine elephants are in demand — and solid feminine social teams are not unusual regardless of whether in the wild or captivity. Which is mainly because male elephants will occasionally dwell by itself or find more compact bachelor herds.

In the wild, the male elephants “might be venturing from unique team to different team of females,” Pilgram-Kloppe said.

Keepers at the St. Louis Zoo also hold elephants healthy with operant conditioning. It is uncomplicated, said Pilgram-Kloppe, in that “it’s applied with good reinforcement.”

“In layman’s terms, if I requested Donna to carry her foot in the air for me, I may well give her a verbal cue, indicating ‘foot,’ and as she responds by lifting that foot up, then I’m gonna say ‘good,’ and possibly give her a banana later on.”
