I often drive several hundred kilometers and spend countless hours outside trying to find wildlife to photograph. However, sometimes it’s much easier. This past week I just had to look out my office window! Sitting in a stand of aspen trees was this great horned owl. Not surprisingly the usual four squirrels that frequent the backyard were nowhere to be seen. I quickly grabbed my camera, took a few photographs and returned to the warmth of my office to watch the owl from a distance.

It is relatively common to see black wolves in North America, but that was not always the case. In fact, the black colouration is actually, in evolutionary time, a recent coat colour inherited from none other then the domestic dog some 10,000 to 14,000 years ago. Genomic studies have shown that prior to this time there were no black wolves. However, this trait was common in dogs and through breeding between the two, this gene has since been incorporated into the North American wolf genome and has provided these wolves with an adaptive advantage. What that advantage is no one really knows. Theories include improved camouflage, which doesn’t hold a lot of weight when you consider that wolves are not ambush predators. Another is that black colouration is linked to other genes that enhance immune function, which would provide these individuals with an obvious advantage. However, this theory has holes as well because there aren’t any black Arctic wolves, which you would expect if black colouration provided such a clear immune advantage but. Whatever the reason, Banff National Park has one of, if not the highest proportion of black wolves anywhere. This black wolf pup is one of six pups born this spring in Banff National Park. Of those six pups, five are black.
I have seen several wood lilies in the Rocky mountain parks but this is the first and only yellow variant I have come across. It was surrounded by the more typical rust coloured form. Unfortunately these plants are becoming more rare as people continue to try to transplant them, with little success, to their gardens.
