I don’t think I’ve ever seen wolves in the wild, I was in Alaska when I was small, I can remember seeing bears but not wolves. These ones aren’t wild they were in a wildlife park just outside of Zurich.
You don’t always need long lenses for wildlife photography, you do need to make them stand out from the rest of the scene though. In a forest on a cold day this can be a little easier, most warm blooded animals will go and sit or stand in the sun, the trees will put most of the scene in shadow, and your subject will remain nice and bright. Apparently the human eye is naturally attracted to brighter areas of an image, this is what a person will see first after that their eyes will wander and see more, for example the other 3 wolves in this image.
