Calgary’s harsh winters can be difficult even for humans, but animals at the Calgary Zoo come from climates across the world.
Kim Walker, the Calgary Zoo’s senior manager of animal care and welfare, says the process of preparing animals for a cold snap is less about adjustments and more about ensuring they remain comfortable.
“Every species has unique physical, psychological, and social needs, and meeting those needs is central to our decision-making,” said Walker.
According to the Alberta Government zoo standards, all zoos in the province must “ensure a suitable environment for the animals.”
Supporting animals indoors
As winter approaches, the primary priority is to ensure that animals have comfortable indoor environments.
These spaces are designed to provide enrichment that supports both physical and mental well-being in the species.
The transition into the indoor spaces is not abrupt.
This process requires planning months in advance to ensure the comfort of all species involved.
Monitoring animals through winter
For some species, such as western lowland gorillas, which spend much of the winter indoors, behavioural monitoring is particularly important.
They are closely observed and have their care routines adjusted as needed.
Giving animals the choice
“Animals are never required to be outside during winter conditions and are always given a choice. Some species, such as free-roaming peafowl, are moved into behind-the-scenes indoor spaces until spring,” said Walker.
The zoo does hold animals that are well adapted to winter, specifically from the Wild Canada and Exploration Asia areas.
Siku, the zoo’s polar bear, along with Sarma and Vasili, who are Amur tigers, are excellent examples of species adapted to winter conditions.
“Many people are surprised to learn that some large African species tolerate cooler temperatures well. Animals such as lions often choose to be outdoors on cool days, especially when habitats include features like heated rocks. Chilean flamingos are fairly cold-hardy birds. You’ll see them outside as long as the temperature is 0 C or above,” said Walker.
“Observing, knowing the animal’s typical behaviour, and responding to these changes is an important part of daily animal care,” said Walker.
