The main problem with canoe photography is that it's hard to hold your camera steady when the canoe is rocking in the water. You'll probably need to use a fast film to get a correct exposure. Tall and graceful, herons are a joy to photograph. I sat in a puddle next to a construction site photographing this tri-colored heron as it strode boldly past. You can also use other kinds of vehicles for stalking birds.
Cars are especially good.
If I'm driving through a good area, I always have my camera, telephoto lens, and beanbag ready on the seat next to me. If I see a bird up ahead, I can roll down my window, turn off the engine, and coast quietly up next to it. With the beanbag draped over the lowered window, I can hold the camera fairly steady and fire away. I have a friend who sometimes uses a bicycle to photograph birds. He rides along a coastal bike path with a camera and telephoto lens slung across his shoulder, bandolero style.
