Lead poisoning in a sample of Maryland mourning doves
A sick mourning dove (Zenuidura macroura) collected in Maryland with 2 lead shot in the gizzard showed acid-fast intranuclear inclusion bodies in the kidney tubular cells. The liver and the tibia contained 72 ppm and 187 ppm lead (wet weight) respectively. Four gizzards from 62 doves killed by hunters contained lead shot. The lead content of 43 dove livers ranged from 0.4-14.0 ppm (wet weight); 40

Histopathology of mallards dosed with lead and selected substitute shot
The histopathological response of male game farm mallards fed lead, three types of plastic-coated lead, two lead-magnesium alloys, iron, copper, zinc-coated iron, and molybdenum-coated iron shot was studied. Mallards fed lead, plastic-coated lead, or lead-magnesium alloy shot developed a similar pathological response, including the formation of acid-fast intranuclear inclusion bodies in the kidney

Case report: Coccidiosis and lead poisoning in Canada geese
Four dead Canada geese (Branta canadensis L.) collected at the Prime Hook National Wildlife Refuge, Delaware were found to have both marked duodenal lesions of coccidiosis and high levels of lead in the liver. Although only one goose had lead shot in the gizzard, all four had levels of lead in the liver suggestive of lead poisoning.

Three species of Plasmodium from Canada geese, Branta canadensis
Studies on Canada geese at the Seney National Wildlife Refuge in northern Michigan during the past few years have uncovered at least three species of Plasmodium: P circumflexum, P. relictum, and P. vaughani. Although rarely observed in direct blood smears from the wild hosts, isodiagnosis, using primarily domestic geese as recipients, revealed a prevalence of 60 percent in random samplings of the

Haemoproteus, a blood parasite, in domestic pigeons and mourning doves in Maryland
The occurrence of Haemoproteus in pigeons throughout the world and in mourning doves in the United States is reviewed. Haemoproteus has previously been reported only once from pigeons in Maryland. During this study it was found in all of 18 pigeons from one area but in none of 12 from an adjacent area. No infections were found in 90 Maryland mourning doves. All of the 10 mourning doves from Florid
