Deer Antlers: A Mammalian Miracle

Of all the beautiful animal displays, perhaps none is quite as majestic as that of deer antlers. Around this time of year, male white-tailed deer (Odocoileus virginianus) parade around the Gault Nature Reserve with their head held high in search of mates. But what exactly are antlers?


Easily mistaken for horns, which are widespread in the animal kingdom, antlers are only found in the Cervidae family. While horns, in most species, can be found in males and females, antlers are usually found only in male deer (except for the caribou, Rangifer tarandus). Most importantly, antlers are the only mammalian organ capable of complete regeneration! Horns stay on an animal’s head all its life and will not regrow if they are injured. Antlers, however, are grown and shed every year.


Scientists study this unique and impressive annual cycle to try to understand mammalian organ regeneration. Current research focuses on understanding the stem-cell-like properties allowing this unique feature of cervids to occur in the hope that it would allow us to regenerate human organs and limbs.

Fair Competition

The pinecones littering the forest floor are good for more than just Christmas garlands—just ask a red squirrel or one of the many birds that see them as a meal, like the red‑breasted nuthatch. This small bird can extract the meaty seeds from the cone with a quick flick of its slender beak. You might also spot one exploring tree trunks, head down, in search of insects hiding in the cracks of the bark to avoid becoming part of a bird buffet. These cracks are also useful as a hiding place for an emergency cold‑weather food stash. The red-breasted nuthatch has the same blue-grey back as the white-breasted nuthatch, but can be distinguished by its smaller size, nasal song, black eye band and, of course, red belly.

Icy trails are common on the mountain in wintertime, especially on steep sections. During your outings at the Reserve, please remember to bring your crampons for a safer hike. Walking poles are a great help too.

Crampons are also available for sale at the Welcome Centre.

Blast from the Past

Ski Jumping on Mont Saint-Hilaire

In 1964, a 30-metre ski jump was built on Mont Saint-Hilaire in what is now the meadow on the Burned Hill trail. The ski jumping area was around 15 metres wide by 40 metres long. Competitions took place from 1965 to 1970. The ski jump was later destroyed, but if you look closely, you can still see a relic of the landing area to this day—the trees there are smaller and sparser.
