Calgary Zoo’s annual penguin walk starts on Friday with special COVID-19 restrictions in place.During the daily walk, the zoo’s king penguins waddle along a designated outdoor route as visitors stand by and watch.The zoo says the walk is good for the penguins’ health and overall well-being.“It stimulates their mind, encourages exercise, and as naturally curious creatures, it offers them a change of scenery and a chance to explore more of their world here at the Calgary Zoo,” a news release explained.This year, the zoo says the walks will have limited viewing capacity and those in attendance will have to stay stationary to help maintain physical distancing.
