 American wood cocks are a small shore bird that nests and mains deciduous force. Perhaps you've heard them at night. Upon migrating back in the spring, male wood cocks will arrive on singing grounds where they have a variety of sounds that they make as part of their courtship. This peat noise is used to announce its presence to females and other competing males. After painting, males take to the air where they make a soft chirping noise accompanied by a mechanical twittering produced from the wind rushing through their notched outer flight feathers. Back on the ground, a barely audible noise sounding like tuko is also given, often preceding each peat. When a female is present, males will walk with wings stretched vertically giving only the soft tuko noise in a final act before courtship.
