Wigeongrass (Ruppia maritima): a literature review
Wigeongrass (Ruppia maritima L.) is a submersed macrophyte of nearly cosmopolitan distribution and worldwide importance as a waterfowl food. Unfortunately, the plant no longer inhabits vast areas disturbed by human activities. Taxonomic status of the plant is uncertain, especially in North America. In mild climates, in habitats subject to environmental extremes, the plant behaves as an annual (veg

Homing and reproductive habits of mallards, gadwalls, and blue-winged teal
We studied mallard (Anas platyrhynchos), gadwall (A. strepera), and blue-winged teal (A. discors) populations on 2 study areas of 22.6-km2 each in central North Dakota during 1976-81. Data regarding rates of return of females to natal or previously used nesting areas, nest site selection, and productivity of hens of different ages were collected from 1,166 nasal-marked and 2,142 banded hens of the

Sago pondweed (Potamogeton pectinatus L.): A literature review
Sago pondweed (Potamogeton pectinatus L.) is a submersed macrophyte of nearly cosmopolitan distribution. The plant is of worldwide importance as a waterfowl food but also can be a nuisance in irrigation canals and recreational areas. The plant reproduces by many different means, depending on habitat and environmental stress. Several genetic ecotypes have evolved. Most important as waterfowl food a

An evaluation of techniques to measure contour feather molt in ducks
We evaluated 3 techniques (air jet, flat skin, grab sample) to assess molt in dead waterfowl (green- winged teal [Anas crecca] and king eider [Somateria spectabilis]). The air jet technique was fast and required no specimen preparation. The flat skin technique required lengthy preparation time after which molt was assessed quickly. Both techniques underestimated the extent of molt (P < 0.01). The

Conditioning of sandhill cranes during fall migration
Body mass of adult female and male sandhill cranes (Grus canadensis) increased an average of 17 and 20%, respectively, from early September to late October on staging areas in central North Dakota and varied by year. Increases in body mass averaged 550 and 681 g among female and male G. c. canadensis, respectively, and 616 and 836 g among female and male G. c. rowani. Adult and juvenile G. c. rowa

Estimating nest success: When Mayfield wins
The Apparent estimator of nest success may be severely biased because unsuccessful nests are less likely to be found than are successful nests. The Mayfield estimator is a preferred alternative. The situation is somewhat different for nests in colonies or on islands because of greater visibility of nests, higher synchrony of nesting, and often higher hatch rates than dispersed mainland nests.
