Commonly referred to as Black squirrels these are actually Eastern Grey squirrels. They are descendants of squirrels that escaped from the Calgary Zoo in the 1930s and can be seen all over the city. I have some that I see regularly on my front lawn

They were among my first test subjects when I bought a Nikon 200-500mm lens. Perfect for long distance shots, in some cases I don't even have to leave my house to get some great closeups of these little critters

Watching them eat is enjoyable as they will be completely oblivious to me as they munch away
