Such delays in nest initiation by scaup are especially alarming, given that scaup are migrating through North Dakota earlier than they did historically. |

|
Canvasback, redhead, lesser scaup and ruddy are a few of the diver ducks. |

On the Firth of Forth, says Northumbrian Water's Mr Spray, large populations of scaup, a diving duck, vanished after the effluent was cleaned up. The European Commission, however, is unflappable. |

|
The species present at these locations are mainly the American black duck, Mallard, American wigeon, Northern pintail, Common goldeneye and scaup species. |
|
For lesser scaup, population declines are most pronounced in the boreal forest region, where recruitment of young and survival of females have also declined. |
|
However, later breeding ground studies conducted in the western boreal forest and parklands found that selenium concentrations in scaup eggs were below critical levels and that most eggs under observation hatched. |
|
Research suggests this change has caused shifts in the types and numbers of aquatic invertebrates in these wetlands, including a reduction in those that female scaup and ducklings prefer to eat. |
|
Research has demonstrated that tests with embryonic liver cell cultures prepared from domestic chickens, Peking ducks and greater scaup and exposed to 18 different PAHs may be used to develop rapid and inexpensive bioassays. |
