Although it seems like it should be a “tail” that a mammal weighing in at more than 3,000 pounds squeaks, it is definitely true. Rhino herds use a variety of vocalizations to communicate with each other — or to communicate that an unknown individual is near, from grunting and snorting to heavy breathing and trumpeting. And, yes, even squeaking! When mother and calf are in the Zoo rhino barn, the vocalization is at a near constant says keeper Alisa Sandor. Calves will snort, snuff and squeak to let their mom know they are ready to nurse or rest. Moms will return the favor, snorting or huffing in response to their own movements or the presence of male Forrest. “Even our male Forrest lets out a tiny squeak when he’s looking for attention from the girls,” said Sandor.
