Lethal mobilization of DDT by cowbirds Lethal mobilization of DDT by cowbirds
This study is an experimental demonstration of lethal mobilization of DDT by brown-headed cowbirds (Molothrus ater) and the effects of food deprivation on the distribution and loss of DDT, DDD, and DDE. The principal experimental group consisted of 20 birds fed a dietary dosage of 100 ppm of DDT for 13 days. After 2 days of full rations of untreated food, they were subjected to food...

Some effects of aldrin-treated rice on Gulf Coast wildlife Some effects of aldrin-treated rice on Gulf Coast wildlife
Wildlife casualties from aldrin-dieldrin poisoning are associated with the planting of aldrin-treated rice seed along the Texas Gulf Coast. The fulvous tree duck (Dendrocygna bicolor), which depends on the rice field habitats and is highly susceptible to aldrin-dieldrin poisoning, is suffering a serious population decline in that area. Dead waterfowl, shorebirds, and passerines were...

Some physiologic blood values of wild diving ducks Some physiologic blood values of wild diving ducks
Blood samples were obtained from 54 canvasbacks (Aythya valisineria), 30 lesser scaup (A. affinis), 3 ring-necks (A. collaris), and 3 buffleheads (Bucephala albeola), which were wintering on Chesapeake Bay. These blood samples were used for: red blood cell counts (cans. 2.56 × 106/mm3; scaup 2.45 × 106/mm3; ring-necks 2.50 × 106/mm3; bufflehead 2.64 × 106/mm3), packed cell volume (cans...

Immunologic status of mourning doves following an epizootic of trichomoniasis Immunologic status of mourning doves following an epizootic of trichomoniasis
An epizootic of trichomoniasis in mourning doves at the Carolina Sandhills National Wildlife Refuge began in 1969 and continued into 1970. The disease was seen in 16% of the adults and 2% of the immatures in 1970, but only one immature bird out of 37 surveyed (3%) carried Trichomonas gallinae. Challenge infection of 33 doves from the epizootic area showed 85 percent to be resistant to

Effect of Hygromycin-B on pigeons (Columba livia) with and without Trichomonas gallinae Effect of Hygromycin-B on pigeons (Columba livia) with and without Trichomonas gallinae
Hygromycin-B was administered in varied quantities to pigeons harboring nonvirulent Trichomonas gallinae and to pigeons free of T. gallinae. Both groups responded identically with large yellow caseous lesions in the upper digestive tract which superficially resembled canker (trichomoniasis). No mycotic association with the lesions could be established in either .group from sections...
