Deer antlers are bone structures, unique to male deer, that grow and are shed annually. Composed primarily of calcium phosphate, they are a mineralized tissue similar to bone. After the breeding season, male deer naturally shed their antlers, leaving them in forests and fields. These shed antlers do not simply decay; they become a significant resource within the ecosystem.
Key Antler Consumers
Rodents, including squirrels, mice, and porcupines, are diligent consumers of shed deer antlers, frequently gnawing on them. Their continuously growing incisors make gnawing a necessity; antlers help wear down their teeth and offer nutritional benefits. They persistently chew on the hard antler material, often leaving distinct parallel grooves from their incisor marks.
Beyond rodents, other animals opportunistically consume antlers. Foxes and coyotes may chew on antlers, attracted by residual scent or mineral content. Even deer and other ungulates, like elk or moose, nibble on shed antlers, suggesting a need for their nutrients. Insects, such as beetle species, also decompose antlers by breaking down organic components.
Why Antlers are a Valuable Resource
Animals consume antlers for their rich mineral content, crucial for various biological functions. Antlers are a concentrated source of calcium and phosphorus, fundamental for strong bone development and maintenance. These minerals are also indispensable for healthy tooth structure and metabolic processes.
Antlers also contain trace minerals like magnesium, potassium, and iron, though in smaller quantities. These minerals are often scarce in certain natural environments, especially during winter or in poor soil. Consuming antlers provides a readily available supplement, helping animals meet daily nutritional requirements when other food sources are limited.
The Scavenging Process
Animals locate shed antlers through scent and opportunistic discovery. While the initial strong scent fades quickly after shedding, a faint mineral scent may persist, attracting animals. More commonly, animals stumble upon antlers during foraging, especially where deer frequently shed them.
Once an antler is found, consumption typically involves persistent gnawing, particularly by rodents. Their strong jaws and specialized teeth allow them to gradually break down the dense material, extracting minerals. This slow gnawing process means an antler can provide a sustained source of nutrients for an extended period. The consumption of antlers by various animals facilitates the return of essential minerals to the soil, contributing to ecosystem nutrient cycling.
