I have come close (or them to my boat LOL) to whales, belugas, turtles, porpoises, and sharks. Flying fish and seagulls have landed on my boat several times, but the strangest encounter happened while crossing from Sept-Iles to Sainte-Anne-des-Monts on the lower St.Lawrence river, a 65 nm trip. About midway, a small, very tired land bird decided to get some rest on the boat. Got so familiar and confident of its safety that he (or she ?) visited inside, then got out again and perched on my shoulder. We fed him some cereals but he preferred pecking at the lines. He stayed with us until landfall several hours later, then flew to a nearby lawn at the marina, where we saw a big tomcat on the prowl. The next morning we discovered what looked like the remnants of the poor bird. Nature life is not easy !!!
