Gray Jays Spend Wintertime at Grouse Mountain
Gray Jays, otherwise known as "Whiskey-Jacks", are frequently seen around Grouse Mountain during the wintertime. They show up about the time of our first snow-fall and stay well into the spring.
Gray Jays are known by many other names: "Lumberjacks", "Venison-hawks", "Meat-birds", "Camp-robbers" and more. By looking at these names the personality of this confident little bird becomes apparent.
Gray Jays have a history of hanging around logging camps and making off with shiny bits of metal as well as mouthfuls of food. They are one species of bird who do not appear to be frightened by humans and they will often land on your hand or shoulder looking for a free meal.
To survive in cold climates, Gray Jays have come up with an innovative solution. During the fall when food is more plentiful, they will take mouthfuls of food and coat it with a sticky saliva solution. The Whiskey-Jack then finds an old woodpecker drilling hole, or other natural crack in the bark of Fir trees, and deposits the food well above the snow-line for later consumption.
Next time you are on the mountain, listen for the "whee-oo" whistle of this thrifty bird and watch for one jumping around a nearby tree.

Santa's Reindeer Arrive at Grouse Mountain
Two of Santa's Reindeer have arrived at Grouse Mountain from the North Pole. Dancer and Vixen showed up late last week and are currently hanging out near Santa's Workshop at the Skating Pond.
Reindeer are domesticated Caribou. In the wild, Caribou live in herds that can number into the hundreds of thousands of individuals. It is quite a sight when the herd begins to move in search of a new food source! Their favourite foods include lichens, mosses and other small vegetation.
Reindeer have been domesticated for thousands of years and in some cultures they play an integral subsistence role. There is evidence of reindeer being domesticated in Northern Asia as early as 499 AD and Reindeer cave paintings up to 25,000 to 30,000 years old have been found in Europe.
Santa's nine reindeer - Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donder, Blitzen and of course Rudolph - are good choices to live at the North Pole since Reindeer are very adapted for cold climates. Their large hooves spread out and act like large snowshoes and the outer hairs of their coat are air-filled, which helps provide added insulation against cold weather.
When they are not flying, Reindeer can run at speeds approaching 50km/hr. Of course, to make it around the world in one evening Reindeer have been known to fly at over 3000 times the speed of sound.
I hope you get to make it up here to visit Santa, Dancer and Vixen and enjoy the Peak of Christmas at Grouse Mountain.
