A buddy of mine shot an illegal swan on a Spring snow goose hunt in Sask. a few years ago. The mate circled around and around making the 'saddest' call of anything I ever heard. I added swan to my "Spirit Bird" list of things I won't shoot, along with Loon, Owls, Ravens, Cranes and those longtailed black and white birds that light on your downed ducks and eat the breast out of them...Geo
