Conservation of migratory raptors: An overview based on fifty years of raptor banding

During the 50-year period 1931-80, 422,000 raptors were banded in the United States and Canada. Encounter rates were calculated, by decades of banding, for all birds reported outside of the l0-min block of latitude and longitude where they had been banded. Encounter rates for the various raptor species decreased from about 15-25% in the 1930s to about 1-5% in the 1970s. The percentage of encounter

Evaluation of a mallard productivity model

A stochastic model of mallard (Anas platyrhynchos) productivity has been developed over a 10-year period and successfully applied to several management questions. Here we review the model and describe some recent uses and improvements that increase its realism and applicability, including naturally occurring changes in wetland habitat, catastrophic weather events, and the migrational homing of mal
