Effects of weather on breeding ducks in North Dakota Effects of weather on breeding ducks in North Dakota
The present report quantifies relations between weather and several aspects of the breeding biology of four duck species: mallard (Anas platyrhynchos), gadwall (A. strepera), blue-winged teal (A. discors), and redhead (Aythya americana). Data were obtained from two locations in North Dakota,--the J. Clark Salyer National Wildlife Refuge, intermittently during 1936-68, and the Northern...

[Book review] The wildfowl of Britain and Europe [Book review] The wildfowl of Britain and Europe
Of about 140 extant species of waterfowl in the world, 54 occur in the western Pale- arctic. In this, his most recent book, Ogilvie introduces the reader to the waterfowl of Europe including occasional visitors and introduced species. Although written primarily for laymen, ornithologists will find the book informative but should not expect a major treatise on European waterfowl. The text...

Breeding bird community colonization of sown stands of native grasses in North Dakota Breeding bird community colonization of sown stands of native grasses in North Dakota
Breeding passerine birds were studied in three native grass plantings of predominantly western wheatgrass (Agropyron smithii) and green needlegrass (Stipa viridula) in south-central North Dakota during 1982-1984. A total of eight different species of passerines readily colonized this relatively new type of wildlife habitat during the second, third. and fourth growing seasons.

Proper expression of metabolizable energy in avian energetics Proper expression of metabolizable energy in avian energetics
We review metabolizable energy (ME) concepts and present evidence suggesting that the form of ME used for analyses of avian energetics can affect interpretation of results. Apparent ME (AME) is the most widely used measure of food energy available to birds. True ME (TME) differs from AME in recognizing fecal and urinary energy of nonfood origin as metabolized energy. Only AME values...

Inheritance patterns of enzymes and serum proteins of mallard-black duck hybrids Inheritance patterns of enzymes and serum proteins of mallard-black duck hybrids
From 1974 to 1976, a breeding program was used to produce hybrids of black ducks and mallards for the evaluation of inheritance patterns of serum proteins and serum, liver and muscle enzymes. In addition to the crosses designed to produce hybrids, a series of matings in 1975 and 1976 were designed to evaluate inheritance patterns of a hybrid with either a black duck or mallard. At the F1...

Swainson's hawk nesting ecology in North Dakota Swainson's hawk nesting ecology in North Dakota
Swainson's Hawks (Buteo swainsoni) were studied at 270 occupied nest sites in south-central North Dakota on a 1,259-km2 intensive study block and on a surrounding study area (16,519 km2) during three breeding seasons. On the intensive study block the number of occupied nests ranged from 46 in 1977 to 100 in 1979. Average nest densities were highest on ground moraine (0.119 nest/km2) and...
