Use whatever you would use for pheasant, grouse or other small game. #6 shot is plenty. Some guys I know have use slingshots in the past if you can get them. The cree use rocks to get them. U can get pretty close to them. I wouldn't bring a BB or pellet pistol. It might get you into some problems at the border. Even Conservation may get nervous when they see a pistol because from a distance you cannot if some of them are real or not and of course in Canada you cannot hunt with or possess a real pistol or revolver other than at a shooting range or at home. I'm bringing a sling shot and my Stoeger o/u .410.
