Estimating nest success: The Mayfield method and an alternative
Douglas H. Johnson
1979, The Auk (96) 651-661
Mayfield's method for calculating the success of a group of nests is examined in detail. The standard error of his estimator is developed. Mayfield's assumption that destroyed nests are at risk until the midpoint of the interval between visits leads to bias if nests are visited infrequently. A remedy is...
Nesting ecology of Arctic loons
Margaret R. Petersen
1979, The Wilson Bulletin (91) 608-617
Arctic Loons were studied on the Yukon-Kuskokwim Delta, Alaska, from the time of their arrival in May to their departure in September, in 1974 and 1975. Pairs arrived on breeding ponds as soon as sufficient meltwater was available to allow their take-off and landing. Loons apparently do not initiate nests...
Earthquakes, September-October 1978
W. J. Person
1979, Earthquake Information Bulletin (USGS) (11) 71-73
The months of September and October were somewhat quiet seismically speaking. One major earthquake, magnitude (M) 7.7 occurred in Iran on September 16. In Germany, a magntidue 5.0 earthquake caused damage and considerable alarm to many people in parts of that country. In the United States, the largest earthquake occurred...
Pomarine jaeger preys on adult black-legged kittiwake
George J. Divoky, Karen L. Oakley, H.R. Huber
1979, The Wilson Bulletin (91) 329-329
On 5 June 1977, while on a cruise in the decomposing pack ice in the Bering Sea, we observed a light phase Pomarine Jaeger (Stercorarius pomarinus) attack, kill and feed on an adult Black-legged Kittiwake (Rissa tridactyla), 1 of approximately 10 individuals within 20 m of the ship's stern. We...
Fall foods of migrant common snipe in North Dakota
E.K. Fritzell, G.A. Swanson, M.I. Meyer
1979, Journal of Wildlife Management (43) 253-257
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...
Mathematics and mallard management
L.M. Cowardin, Douglas H. Johnson
1979, Journal of Wildlife Management (43) 18-35
Waterfowl managers can effectively use simple population models to aid in making management decisions. We present a basic model of the change in population size as related to survival and recruitment. A management technique designed to increase survival of mallards (Anas platyrhynchos) by limiting harvest on the Chippewa National Forest,...
PCBs and DDE in commercial fish feeds
Michael J. Mac, L.W. Nicholson, C.A. McCauley
1979, Progressive Fish-Culturist (41) 210-211
Three commercial fish feeds were analyzed for PCBs and p,p' DDE and were reported in dry weight concentrations. In various sizes of Oregon Moist Pellets, concentrations of PCBs ranged from less than 0.10 to 0.30 I?g/g and those of p,p' DDE from less than 0.01 to 0.47 I?g/g. In Silver...
