Manatees respond to high ambient noise by feeding more and milling less
Evidence
Changes in behavior has been observed in the manatee (Trichechus manatus latirostris) by Miksis-Olds and Wagner (2011). This species when the ambient noise is high spends more time feeding and less time milling (undirected movement). The increased foraging activity can be explained as an attempt to meet nutritional requirements in the shortest time possible when experiencing noise disturbance that could be considered a menace or a dangerous situation. β Almo Farina, Soundscape Ecology, 1358
