A variable circular-plot method for estimated bird numbers
A bird census method is presented that is designed for tall, structurally complex vegetation types, and rugged terrain. With this method the observer counts all birds seen or heard around a station, and estimates the horizontal distance from the station to each bird. Count periods at stations vary according to the avian community and structural complexity of the vegetation. The density of each

Atlantic Flyway review: Region V
Four of last year's Maryland stations were either discontinued or banded too few birds to report their results in 1978; these were Cloisters in Baltimore County, Cylburn in Baltimore City, tum Suden Sanctuary in Harford County, and Sandy Point State Park in Anne Arundel County. Banding was severely curtailed at Damsite, Maryland's last remaining Eastern Shore Station. Each of the other stations in

Computer simulation models as tools for identifying research needs: A black duck population model
Existing data on the mortality and production rates of the black duck (Anas rubripes) were used to construct a WATFIV computer simulation model. The yearly cycle was divided into 8 phases: hunting, wintering, reproductive, molt, post-molt, and juvenile dispersal mortality, and production from original and renesting attempts. The program computes population changes for sex and age classes during ea
