During the annual molt, waterfowl have a complete and simultaneous molt of their wing feathers, which leaves them flightless for 2 to 4 weeks. Ducks often desert their breeding grounds, prior to the molt, in search of food-rich waters and areas that provide protection from predators while they are flightless. In the United States and Canada signed the _____, which called for joint management of waterfowl and their habitats. Migratory Bird Treaty Act ________ provide a generous, high-protein diet for young waterfowl.
Aug. 1, — Red knots make an amazing journey from their breeding grounds in the Canadian Arctic to their winter habitat in South America and back each year. Their numbers have fallen. Throughout the Great Plains, riverine systems function as critical stopover sites for migratory waterbirds to refuel and prepare for their arrival on the breeding grounds. The North Platte River, with channels and associated wetlands that extend eastward more than miles from the Nebraska /Wyoming state line, is an example of both the.
Migratory birds—be they waterfowl, shorebirds, long-legged waders, raptors, songbirds, or other groups—require stopover sites as they make their way north each spring to their breeding grounds throughout North America, and then again on their return to wintering areas. Following instinct and other cues, the birds follow well-established routes, known as flyways. The Prairie Pothole Region (PPR) is an expansive area of the northern Great Plains that contains thousands of shallow wetlands known as potholes are the result of glacier activity in the Wisconsin glaciation, which ended ab years decaying ice sheet left behind depressions formed by the uneven deposition of till in ground moraines.

This is a plea for the protection of the few suitable breeding grounds still remaining for these birds if we would save them from extermination.
This was a very positive move for the conservation of duck habitat on private lands in the PPR, because the bulk of waterfowl habitat is privately owned and landowner interest is high.
Cooperation with landowners is central to DU's "Grasslands for Tomorrow" initiative, which seeks to protect the best remaining waterfowl habitat on the continent. The Northern Great Plains is considered one of 67 areas of continental significance to North American waterfowl in the North American Waterfowl Management Plan (NAWMP).
A significant portion of North America’s continental waterfowl population either breeds or migrates through the NGPJV area. While the NGPJV provides important spring and fall migration habitat for waterfowl, it is most.
Come as you are and leave different. Like people, waterfowl rely on certain cues to prepare them for important activities.
For example, as day length increases in late winter, waterfowl sense that it's time to start "packing" for their long journey north to the breeding grounds. They prepare for the trip by consuming large quantities of high-energy foods such as moist-soil plant seeds, invertebrates, and agricultural waste grains.
These lands provide critical habitat for waterfowl, grassland song birds, and other resident wildlife. South America this little bird migrates at least 5, miles to its breeding grounds in grasslands of the Northern great plains.
Populations are in decline due to grassland conversion in their wintering and breeding grounds. Kaylan Carrlson is manager of conservation programs and Tanner Gue is a biologist in DU's Great Plains Region.
The Importance of Migration and Wintering Habitats Although studies have shown that events occurring on the breeding grounds have the largest impact on annual waterfowl populations, migration and wintering habitats also play a vital role in sustaining the birds throughout their annual.
This report includes the most current breeding population and production information available for waterfowl in North America and is a result of cooperative eforts by the U.S.

The primary breeding grounds for geese using the Pacific Flyway are the Yukon, Kuskokwin, and Copper River deltas and the north and west coasts of Alaska.
These birds typically winter in. Prairie potholes are important natural resources for people as well as waterfowl. They provide valuable, but often under-appreciated, ecosystem services that help people commercially, ecologically, and economically. They serve as natural sponges that hold excess water, which helps reduce the severity and risk of downstream flooding.

While 13 percent lower than last year's million breeding population figure, this year's number is still 17 percent above the long-term average (LTA) from Author: Lynn Burkhead. Participation growing in Ducks Unlimited's winter wheat incentive program October 26th, Printer-Friendly Version.
BISMARCK, N.D., Oct. 26, - More North and South Dakota farmers are choosing to plant winter wheat and that means a higher success rate for ducks nesting in those fields, according to Blake Vander Vorst, Ducks Unlimited’s (DU) regional agronomist in the Great Plains.

In fact, snow goose numbers have exploded, such that they actually damage their nesting grounds by feeding too heavily.
There have even been controversial spring seasons with high bag limits to reduce the snow goose population. Here's what state waterfowl biologists expect for the coming waterfowl seasons in the Great Plains.
