Survival and other observations of adult female northern pintails molting in California Survival and other observations of adult female northern pintails molting in California
Survival rates of nine adult female Northern Pintails (Anas acuta) that became flightless after being radio-marked in the Sacramento Valley, California in August 1987-1989 were estimated. Seven of the radio-marked pintails molted in the Sacramento Valley, a nontraditional molting region, and two flew 280 km north to the Klamath Basin to molt. Molting marshes were dominated by emergent...

First flowering dates and flowering periods of prairie plants at Woodworth, North Dakota First flowering dates and flowering periods of prairie plants at Woodworth, North Dakota
We recorded flowering events for 97 species of prairie plants for 2-6 years near Woodworth, ND. Earliest and latest flower initiation dates varied by year. Temperature seemed much more important than precipitation in influencing phenology of species that bloom from late March through May, but no strong climatic effect was evident for plants that bloom later in the growing season.

Does supplemental feeding of red squirrels change population density, movements, or both? Does supplemental feeding of red squirrels change population density, movements, or both?
Supplemental feeding increased the number of red squirrels (Tamiasciurus hudsonicus) captured on two trapping grids, leading Sullivan (Journal of Mammalogy, 71:579–590, 1990) to infer that the population density of residents had increased. This conclusion is questionable because the residency status of captured squirrels was unknown.

Diurnal flight time of wintering Canada geese: consideration of refuges and flight energetics Diurnal flight time of wintering Canada geese: consideration of refuges and flight energetics
We monitored individual radio-equipped Canada geese (Branta canadensis) associated with a federal refuge to assess flight activities from late fall through spring. The number of flights per day was lowest in late fall when most geese remained within the refuge and highest in spring when they moved increasingly beyond the refuge area. The only significant seasonal difference in flight...

Application of a computer simulation model to migrating white-fronted geese in the Klamath Basin Application of a computer simulation model to migrating white-fronted geese in the Klamath Basin
The Pacific greater white-fronted goose (Anser albifrons) population has declined precipitously over the past 20 years. Loss of wetland habitat in California wintering areas has had a significant effect on the population, so recovery of the population may depend on innovative management of the few remaining wetlands. A computer simulation model, REFMOD, was applied to greater white...

Standing crops and ecology of aquatic invertebrates in agricultural drainwater ponds in California Standing crops and ecology of aquatic invertebrates in agricultural drainwater ponds in California
We examined standing crops and ecology of aquatic invertebrates in agricultural drainwater evaporation ponds in California from October 1982 to March 1983 and September 1983 to March 1984. Evaporation ponds supported low diversities but high standing crops of aquatic invertebrates. A water boatman (Trichocorixa reticulata) and a midge (Tanypus grodhausi) were the most abundant...

Brood parasitism among waterfowl nesting on islands and peninsulas in North Dakota Brood parasitism among waterfowl nesting on islands and peninsulas in North Dakota
During 1985 and 1986 I studied interspecific brood parasitism among seven species of waterfowl nesting on 36 islands and 24 peninsulas in central North Dakota. On islands, 40% of 178 nests were parasitized with an average of 4.3 parasitic eggs, and on peninsulas 2% of 275 nests were parasitized with an average of 2.2 parasitic eggs. Redheads (Aythya americana) were the primary parasite...
