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

Organochlorine pesticide, PCB, and PBB residues and necropsy data for bald eagles from 29 states - 1975-77
During 1975-77, 168 bald eagles (Haliaeetus leucocephalus) found moribund or dead in 29 states were analyzed for organochlorine pesticides and polychlorinated biphenyls (PCBs); 32 specimens from 13 states were analyzed for polybrominated biphenyls (PBBs). PCBs were present in 166 bald eagle carcasses and DDE was found in 165. TDE and dieldrin were identified in 137 samples, trans-nonachlor in 118,

White-faced ibis populations and pollutants in Texas, 1969-1976
Eggshell thickness, levels of pollutant residues, and population status of the white-faced ibis (Plegadis chihi) were monitored in Texas from 1969 through 1976. Texas ibis nesting populations declined by 42%. Reproductive success apparently was limited by DDE-induced shell thinning and by dieldrin-caused mortality. Eggshells averaged 4% to 10% thinner than the pre-1943 mean thickness. Shells of nu
