Canada Goose
Branta canadensis
The Canada goose usually makes a two note kaa-ronk or ahonk The male has a somewhat lower voice than the female. Here are two geese apparently alarmed by my presence, even though I was 150 ft away across a marsh. Eventually they worked themselves into such a pitch of excitement that they flew. Here are the calls of three geese flying into a marsh at twilight. (Albany County, New York.)
Habitat: lakes, ponds, marshes, fields (also nowadays, golf courses, parks, lawns)
Trumpeter Swan
Cygnus buccinator
This swan is named for its trumpet call. Swans trumpet when defending territory, when excited, and to promote family or flock cohesion. In this case, a pair was swimming across a pond at sunset, apparently undisturbed, when one of the pair trumpeted. (Burnett County, Wisconsin)
Habitat: Breeds on freshwater ponds, lakes and marshes.
Wood Duck
Aix sponsa
The most commonly heard call of the Wood Duck is a squeal, ooEEK, given by the female. One version is used when she flies into a new area or approaches males and may serve as an advertisement. A shortened version is used as an alarm. The calls presented here were given by an alarmed hen leading ducklings away across a pond. (Albany County, New York.)
Habitat: Swamps, ponds, rivers with trees.
Mallard
Anas platyrhynchos
The familiar quack of the Mallard is made only by the female. This bird was startled by something unidentified. The female Mallard also often calls in flight. (Albany County, New York)
Habitat: Marshes, ponds, lakes, bays, city parks.
