Why Some Bucks Grow 3 Beams

Triple-beamed buck 1.The biggest deer in the woods are often the result of great genetics and good deer feed, but there are exceptions.

Take, for example, the case of this triple-beamed buck. My friend (and Deer & Deer Huntingfield editor) Les Davenport reports that there’s a surge in the number of triple-beamed bucks showing up on trail cameras in Illinois. What are causing so many deer to have these odd antlers? It could be myriad factors, but a likely cause might be cranial abscess disease. CAD occurs when a buck severely injures one or both of his pedicles. This happens a lot on properties with higher numbers of huge deer (fights during the rut). According to deer researcher Dr. David Samuel, these injuries can result in abnormal growth either from the pedicle or the boney part of the deer’s skull.

Triple-beamed buck 2.“This growing cell mass creates tension on collagen fiber bundles at the base of these growing antlers,” Samuel reports. “If there is any damage when the antler starts to grow, it may move these fibers to other parts of the skull near the pedicle and that might lead to nontypical points.”
