Canada Goose with Dirty Mouth
While it is not too hard to find a human-tolerant Canada goose, getting a nicely-framed and in-focus head shot of one of these birds is much more challenging. The head and that long neck are constantly moving and at this distance, depth of field is shallow. So, the person behind the camera must be quick to focus and shoot before the head goes out of focus.
