avian influenza viruses and avian paramyxoviruses in wintering and breeding waterfowl populations in north carolina, usa.although wild ducks are recognized reservoirs for avian influenza viruses (aivs) and avian paramyxoviruses (apmvs), information related to the prevalence of these viruses in breeding and migratory duck populations on north american wintering grounds is limited. wintering (n=2,889) and resident breeding (n=524) ducks were sampled in north carolina during winter 2004-2006 and summer 2005-2006, respectively. overall prevalence of aiv was 0.8% and restricted to the winter sample; however, prevalence ...201121270016
accumulation of environmental contaminants in wood duck (aix sponsa) eggs, with emphasis on polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans.we measured polychlorinated dibenzo-p-dioxins (pcdds), polychlorinated dibenzofurans (pcdfs), polychlorinated biphenyls (pcbs), organochlorine pesticides, and mercury in wood duck (aix sponsa) eggs collected near a north carolina (usa) bleached kraft paper mill. samples were taken a decade after the mill stopped using molecular chlorine. using avian toxic equivalency factors, 2,3,7,8-tetrachlorodibenzo-p-dioxin toxicity equivalent (teq) concentrations were 1-30 pg/g fresh wet weight in eggs (n = ...200818726540
hematozoa of wood ducks (aix spons) in the atlantic flyway.a total of 213 wood ducks (aix sponsa) from 24 localities in 12 states in the atlantic flyway was examined for blood parasites in 1976 and 1977. hematozoa were present in birds from every collection site from virginia northward to maine. only one infection was detected in birds from north carolina southward to florida. haemoproteus nettionis was the most common parasite, occurring in 56% of the northern wood ducks; leucocytozoon simondi (20%), plasmodium circumflexum (6%), and microfilariae (18% ...19806774111
