Foraging strategies of granivorous dabbling ducks
wintering in protected areas of the French Atlantic coast.
Autumn foods of dabbling ducks
in southeastern Alaska.
First, we predicted that opportunistic shorebirds and dabbling ducks
would use any suitable microhabitat available in the landscape and that more appropriate conditions would exist in areas with macrotopography.

(Anus)," William E.
The common dabbling ducks
are the familiar Mallard, now accompanied by Teal, Gadwall and - particularly when the temperatures start to drop - Wigeon.
such as mallards tip down in the water with their tails poking up while they are feeding.
Age of the oldest giant Canada goose ever recorded 65 Percent is the annual mortality rate of the blue-winged teal, the highest among dabbling ducks
At least 47 species of shorebirds, as well as great blue herons, trumpeter and tundra swans, lesser snow geese and dabbling ducks
use this critical habitat.
Double brooding has been documented less frequently in several other species of dabbling ducks
including White-cheeked Pintail (Anas bahamensis) (Sorenson et al.
had slightly higher detection rates (224/7,607, 2.
This study was designed to verify if flight speeds are varied between species of dabbling ducks
and if difference in wing morphology could be attributed to these differences.
Nest parasitism is relatively uncommon among dabbling ducks
, except for cavity nesting or ducks that crowd together on nesting islands (Sayler 1992).
Our study supports the consensus that dabbling ducks
are more likely than diving ducks to be positive for AIV; however, as others have documented, not all dabbling ducks
are equally likely to be AIV positive (2,23,33).
The prairie marshes produce incredible numbers and varieties of diving and dabbling ducks
, and in the past two decades, the province has become a machine for producing Canada geese.
Recently, all duck species, especially dabbling ducks
, have been assessed as high-risk species for possibly contributing to the transmission of HPAIV (H5N1) (15).
