Why Do Moose Antlers Fall Off
Moose antlers fall off because the animal sheds them every year after the mating season. A bony layer called the burr forms at the base, cutting off blood supply. Once the antler dies and the burr seals, the antler drops naturally. This process is part of the annual antler cycle in cervids.
How Moose Antlers Grow Back
After shedding, new antlers begin growing immediately. Antler growth is one of the fastest forms of mammalian tissue, fueled by blood vessels in the velvet. By late summer, the velvet dries and peels away, leaving hardened bone. The cycle repeats each year as daylight and hormone levels change.
When and Where Moose Shed Antlers
Most moose shed their antlers in late winter or early spring, often between December and March. The exact timing depends on age, health, and local conditions. Hunters and wildlife trackers look for shed antlers in forests, fields, and along trails where moose travel frequently.
Key Facts About Moose Antler Shedding
Shedding is driven by a drop in testosterone after the rut ends. Healthy bulls may shed earlier than younger or weaker animals. Shed antlers provide calcium and other nutrients to small mammals and rodents. For more details, see the Smithsonian National Museum of Natural History page on cervid antlers.
