Habitat:

• Will flock together on shallow freshwater ponds, lakes and estuaries; occasionally on salt water bays.
• Prefers wetlands, shallow ponds or slow-moving rivers near grassy areas.
• Eats mostly plant matter such as wild celery and arrowhead tubers. Will occasionally eat farm crops. During winter will also eat mussels, crawfish and snails.

Notes:

• Call is a high-pitched “hoo-hoo-hoo,” which is repeated by the entire flock, producing a high-pitched whistling sound.
