My son and I saw this bird while out for a drive on the Kingston Peninsula. As soon as we stopped the car, it came out of its nest and started circling around us. I think it is a hawk. – Nancy Stacey, Saint John Nancy’s instincts are good – it is a hawk. It’s an osprey, or “fish hawk,” a predator species whose diet consists almost entirely of fresh fish that it catches by flying watchfully over water and plunging in to capture the prey in its talons. Ospreys build a conspicuous stick nest in a large (usually dead or dying) tree or sometimes on a platform on a power line, such as was the case here. They are wary but not particularly shy and utter a series of piping alarm calls when they perceive danger. – Jim Wilson
