February 1991


Pyrotechnics and helicopter fly overs were used to harass double-crested cormorants (Phalacrocorax auritus) at 4 roost sites in the Delta region of Mississippi. Roosting cormorants were easily dispersed from 3 of the 4 sites. Average numbers of cormorants observed at selected catfish (Ictaluridae) ponds and day roosts near foraging areas also declined after harassment began.
