BEHAVIOR
The Mariana fruit dove has a relatively small territory but will move within that territory to follow the ripening of the fruit on various trees. They are shy birds, and are more often heard than seen. The female usually lays her egg in a platform of loosely woven twigs and tendrils nestled in the fork of a tree, six to 20 feet (2–6 m) above the ground. The bird’s call is a loud, repeated "hoo coo" that becomes faster and ends as a rapid "coo coo coo coo coo." Courtship rituals involve the male bowing repeatedly to the female. Both the chick and egg are tended by both parents.
