Although Nuthatches are very common in Calgary I really haven’t encountered very many of them. They are very interesting birds that are known for their unique ability to face head-down while climbing. Most other birds use their tails to assist with balance while climbing, but nuthatches use only their legs and claws. They can often be seen walking straight down the trunk of a tree. This behavior seems very odd when you first recognize what they are doing, and only becomes more odd as you realize that very few birds do it.
