Antler Velvet - Caught in the Act

Male deer, elk, and moose have antlers, which they shed every spring, only to re-grow them again over the summer. ACES staff was lucky to catch a critical part of this annual cycle on our trail cameras recently at Hallam Lake.

Deer and elk typically shed their antlers around March and April, when the animals’ testosterone levels are at their lowest. The decreased amount of testosterone causes the bone connecting the antler to the skull to deteriorate, enabling the antler to fall off.
