Zoo Grizzlies Begin Hibernation

With the colder temperatures setting in, grizzly bears Mistaya (miss‑TIE’‑yuh) and Koda (KOH’-dah), have started hibernation at the Saskatoon Forestry Farm Park & Zoo (Zoo) for the second time.

Preparation for the bears’ hibernation has been underway for several weeks, and the Zoo has worked closely with Dr. Marc Cattet of fRI Research and Deb McWilliams, Wildlife Nutritionist with the Nutritional Advisory Group, to carefully monitor the bears’ diet leading into hibernation.

“We adjusted Mistaya and Koda’s diet to better simulate what a wild grizzly bear would consume in nature,” said Dr. Cattet.  “This adjustment resulted in both bears entering hibernation with body weights similar to what we would expect wild grizzly bears to weigh; around 325 to 350 kg.”

The bears’ second hibernation provides a great opportunity for the Zoo to gather information in relation to conservation, research, and educational initiatives for grizzly bears.  This year, the Zoo will be monitoring the bears’ activity in relation to the den and outside temperatures, which will provide insight into the potential effects a warming climate has on hibernation success.

“While we expect to see a lot of sleeping during late winter when we start to get occasional stretches of warmer days, the bears might wake up temporarily from their hibernation sleep and move around their den for several hours at a time before returning to a hibernating state,” said Dr. Cattet.

Cameras have been installed in the hibernation dens so that the Zoo can closely monitor behaviour, activity levels, and breathing patterns.  Efforts are underway to set up a live camera feed for residents to check in on Mistaya and Koda throughout their hibernation.  The live camera feed will be available in the coming weeks on saskatoon.ca/zoo.

“We are very excited to provide an opportunity for people to get a ‘behind the scenes’ look at what actually happens during hibernation,” said Tim Sinclair-Smith, Zoo Manager.
