Includes bibliographical references (p. 26-27). "We studied the use of natural habitat and artificial platforms by nesting Black Terns (Chlidonias niger) over the 1997 breeding season at an impoundment near Kingston in southeastern Ontario. The impoundment had eight fairly distinct habitat types. Early in the season, nesting was restricted to the "Rushes Marsh" and "Willows Marsh", the only two areas in the impoundment with hemi-marsh conditions at that time"--Abstract.
