Coos are considered calling when a pigeon lengthens the sound. Calling is used for communication, especially when a pigeon attempts to attract a mate. Grunting noises are also made by pigeons in distress as a warning or sound of alarm. While cooing, pigeons may also strut or engage in tail-fanning and bowing.
In addition to vocal sounds, pigeons can also create noises by stamping their feet or slapping their wings together directly prior to taking flight.Learn more about Birds
