There's a family of peregrine falcons that nest every year at the top of one of the hotels right in downtown Ottawa. As soon as it gets warm and they start to nest, the falcon foundation sets up shop in the government building across the street and you can watch them (they've set up cameras and everything). It's really neat, because they hunt for food right in the area, and sometimes you can see them dive and snatch a pigeon. :P When it's not nesting season, or when the chicks are big enough to go off on their own, the falcons stay in the area. They head out to the experimental farm area of the city (a bit west out of downtown). - darkpen
