Penny Kalk began working with elephants at WCS’s Bronx Zoo in 1976, looking after the youngest members of the herd. Today, she continues to oversee their care as Collections Manager for the Mammal Department. With her intimate understanding of individual animals, Kalk recently traveled to Laikipia, Kenya, to aid field colleagues studying elephant demographics and movement patterns.
