Fall foods of migrant common snipe in North Dakota Fall foods of migrant common snipe in North Dakota
Studies of foods consumed by common snipe (Capella gallinago) during fall migration (Sperry 1940, Erickson 1941, Choate in Tuck 1972, Tuck 1972) have shown that diets vary among habitats. More recently, Fogarty and Arnold (1977) expressed the need for more detailed information on snipe food habits and more refined knowledge of the snipe's range and adaptability to various food situations...

Early imprinting in wild and game-farm mallards (Anas platyrhynchos): Genotype and arousal Early imprinting in wild and game-farm mallards (Anas platyrhynchos): Genotype and arousal
Early imprinting was studied under laboratory conditions in five lines of mallards (Anas platyrhynchos) with different degrees of wildness obtained through pedigreed breeding. Data were analyzed by the least squares method. Wild ducklings imprinted better than game-farm (domesticated) ducklings, and heterosis was demonstrated to exist in imprinting traits. Nonadditive genetic variations...

Interpreting the results of nesting studies Interpreting the results of nesting studies
Nesting studies are used to assess the production of birds and to evaluate nesting habitats. Most such studies involve finding nests in a given area and subsequently determining the proportion that hatched. Unfortunately, the results are often biased by unrecognized differences in the probabilities of finding successful and unsuccessful nests. The observed hatch rates of 1,900 nests of...

Red fox prey demands and implications to prairie duck production Red fox prey demands and implications to prairie duck production
Experiments were conducted during spring and summer with 33 red foxes (Vulpes vulpes) to determine prey demands, feeding characteristics, and growth rates using natural foods. Pups began eating prey the 4th week after birth. Then, prey consumption averaged 1.38 and 1.90 kg/pup/week for weeks 5-8 and 9-12 of the denning season respectively, and 2.54 kg/pup/week for the postdenning period...
