The mtDNA cytochrome c oxidase subunit I (COL) genetic variation has been used to discriminate and establish the phylogenetic relationships among Korean dabbling duck
species (Jin et al.
Foraging strategies of granivorous dabbling ducks
wintering in protected areas of the French Atlantic coast.
Overall, these wetlands had 4 times more diving ducks than dabbling ducks
, but this relationship was driven principally by abundance of Lesser Scaup (Table 1).
In 2001 and 2002, we monitored the response of three indicator communities migratory shorebirds, dabbling ducks
, and breeding amphibians - to microhabitat features such as water depth and hydroperiod in areas with and without macrotopography enhancement.
Most of the dabbling ducks
that winter in south Louisiana stay in the freshwater marshes because that's where their food is," says Delta Waterfowl scientific director Dr.
Other vulnerable birds include the endangered red knots and piping plovers that winter in coastal Florida, as well as the green-winged teal, the American widgeon and other dabbling ducks
, loons, white-fronted geese, sandpipers, turnstones, and dowitchers.
There are dabbling ducks
, Western sandpipers, barn swallows, red-shouldered hawks, osprey, bald eagles and peregrine falcons in the area, and they all thrive in tidal estuaries.
prefer shallow, ephemeral wetlands with emergent vegetation like the SWMA and several species of dabblers often use the SWMA (IDFG 2005).
From my study of dabbling ducks
, I have come to believe that formation of hybrids is common during speciation events.
Significant correlations between T1 contents in kidney and liver were observed for all dabbling ducks
except mallard (Anas platyrhynchos); similar correlations were not observed in diving ducks.
Brown wrote this: "I am not familiar specifically with any research on Muscovy ducks for mosquito control, but dabbling ducks
like mallards, readily consume mosquito larvae in wetlands.
3:00 BREAK 3:20 "Correlation between variation in flight speeds and wing morphology of North American dabbling ducks
(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.
