Wish I could take credit for the timing, but I had to take quite a few shots to end up with ONE with its mouth open, mid-screech. Almost without fail, by the time my camera had processed an image, this little Columbian Ground Squirrel's mouth was closed again : ). Not sure if I noticed the Mosquito on its head when I was taking the photo. Saw this little guy/gal while we were enjoying (thoroughly enjoying!) a Strawberry Milkshake at Kananaskis Village after a day of hiking Ptarmigan Cirque Trail. Thanks Robin and Cedric! These Ground Squirrels are a different species from the Richardson's Ground Squirrels that are found in the city.
