M. P. Dieter, Stanley N. Wiemeyer
1978, Comparative Biochemistry and Physiology, Part C: Comparative Pharmacology (61) 153-155
1. Activities of creatine phosphokinase, glutamic oxalacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase, fructose diphosphate aldolase and cholinesterase were measured in plasma of bald eagles.2. There were no sex differences in the plasma enzyme activities.3. An acute dieldrin dosage (10 mg/kg) of a female bald eagle resulted in 400% increases...

D. R. Clark Jr.
1978, Bulletin of Environmental Contamination and Toxicology (19) 707-714
In a previous study (CLARK and LAMONT 1976), 26 pregnant big brown bats were captured, caged, and fed uncontaminated mealworms until their litters were born. Immediately after parturition, female bats and litters were frozen. Five litters included at least one dead young, and these five litters contained significantly more of...
Avian cholera and organochlorine residues in an American oystercatcher
L. J. Blus, L. N. Locke, E. Cromartie
1978, Estuaries (1) 128-129
Pasteurella multocida, the causative bacterium of avian cholera, was isolated from cultures of the liver and heart blood of a female, adult American oystercatcher (Haematopus palliatus) found dead on the Cape Romain National Wildlife Refuge, South Carolina, in May 1973. This is apparently the first record of avian cholera in...

Richard C. Banks
1978, The Auk (95) 348-352
There are two distinguishable subspecies of the Black-bellied Whistling-Duck, one in South America to eastern Panama and one from western Panama through Central America to the southernmost United States. The type locality of the species is the West Indies, but there is little evidence that birds from that area are...
Prealternate molt in nuthatches
Richard C. Banks
1978, The Auk (95) 179-181
Nuthatches of the genus Sitta constitute one of the passerine groups in which prealternate (prenuptial) molt is generally believed not to occur. Dwight (1900: 298) discussed this genus with the family Paridae and stated: "All the members of this family have only the annual moult. They are peculiar in assuming...
Dieldrin-induced mortality in an endangered species, the gray bat (Myotis grisescens)
D. R. Clark Jr., R. K. LaVal, D. M. Swineford
1978, Science (199) 1357-1359
Brains of juvenile gray bats, Myotis grisescens, found dead beneath maternity roosts in two Missouri caves contained lethal concentrations of dieldrin. One colony appeared to be abnormally small, and more dead bats were found a year after the juvenile bats had been collected. This is the first report to link the...
Habitat selection by breeding red-winged blackbirds
P.H. Albers
1978, The Wilson Bulletin (90) 619-634
Habitat preferences of breeding Red-winged Blackbirds in an agricultural area were determined by comparing population density, landscape characteristics, and vegetational descriptions. Observations were made throughout the breeding season. Preferred breeding habitats of Red-wings, in order of preference, were wetlands, hayfields, old fields, and pastures. Males and...
The effects of petroleum on different stages of incubation in bird eggs
P.H. Albers
1978, Bulletin of Environmental Contamination and Toxicology (19) 624-630
Artificially incubated mallard eggs were treated externally with 5 μl of No. 2 fuel oil or 5 μl of Southern Louisiana crude oil at various times during the incubation period. Embryos were most sensitive to petroleum during the first 10 days of incubation. Southern Louisiana crude...
Organochlorine residues and eggshell thinning in anhingas and waders
Harry M. Ohlendorf, Erwin E. Klaas, T. Earl Kaiser
1978, Conference Paper, Proceedings of the 1977 conference of the colonial waterbird group
Residues of organochlorine compounds occur commonly in environmental samples and have been associated with adverse effects in numerous avian species (Cooke 1973; L. F. Stickel 1973; W. H. Stickel 1975; Ohlendorf et al. 1977; H. M. Ohlendorf, R. W. Risebrough, and K. Vermeer, unpublished manuscript). The affected species are...

Distribution and abundance patterns of the palila on Mauna Kea, Hawaii
Charles van Riper III, J. Michael Scott, D.M. Woodside
1978, The Auk (95) 518-527
Censuses of the known geographical range of the rare and endangered Palila were conducted in January (nonbreeding season) and September (breeding season) 1975. The habitat (mamane and naio forest of Mauna Kea, Hawaii) was divided into five major areas, with each analyzed for vegetational composition, phenology of the predominant tree...
Differential use of fresh water environments by wintering waterfowl of coastal Texas
Donald H. White, D. James
1978, The Wilson Bulletin (90) 99-111
A comparative study of the environmental relationships among 14 species of wintering waterfowl was conducted at the Welder Wildlife Foundation, San Patricia County, near Sinton, Texas during the fall and early winter of 1973. Measurements of 20 environmental factors (social, vegetational, physical, and chemical) were subjected to multivariate statistical methods...
Uptake and retention of dietary cadmium in mallard ducks
Donald H. White, M. T. Finley
1978, Environmental Research (17) 53-59
Adult mallard ducks fed 0, 2, 20, or 200 ppm of cadmium chloride in the diet were sacrificed at 30-day intervals and tissues were analyzed for cadmium. No birds died during the study and body weights did not change. The liver and kidney accumulated the highest levels of cadmium. Tissue...

Histopathologic effects of dietary cadmium on kidneys and testes of mallard ducks
Donald H. White, M. T. Finley, J. F. Ferrell
1978, Journal of Toxicology and Environmental Health (4) 551-558
Mallard ducks fed 2, 20, or 200 ppm cadmium chloride were sacrificed at 30, 60, and 90 d. No mortality occurred during the study and body weights remained unchanged. Kidney weights of the 200-ppm group were significantly greater after 60 and 90 d than those of controls; also, testis weights...
Influence of laying on lead accumulation in bone of mallard ducks
M. T. Finley, M. P. Dieter
1978, Journal of Toxicology and Environmental Health (4) 123-129
Paired mallard ducks (Anas platyrhynchos) were given No. 4 lead shot, and bone lead concentrations were compared in drakes and in laying and nonlaying hens. Lead accumulation was significantly greater in bones with a high medullary content (femur and sternum) compared with bones with a lower medullary content (ulna-radius or...
Rehabilitation of birds oiled on two mid-Atlantic estuaries
Matthew C. Perry, Fred Ferrigno, Fairfax H. Settle
1978, Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies (32) 318-325
An estimated 52,500 birds died as a result of 7 major oil spills on 2 mid-Atlantic estuaries between 1973-78. Ruddy ducks (Oxyura jamaicensis) constituted 98% of 12,500 birds known to have died from 5 spills on the Delaware River. Seventy-six percent of 40,000 dead birds from 2 Chesapeake Bay spills...

S.R. Wilbur
1978, North American Fauna No. 72
The California condor (Gymnogyps californianus) was studied on about 900 field days between 1966 and 1976. In addition, some 1,000 items of literature, specimen records from 56 museums, and 3,500 reports of condor sitings by cooperators were analyzed. Distribution does not appear to have changed significantly since the...

About 31 pairs of peregrines still nest north of Mexico, from Idaho and Montana south through West Texas, New Mexico and Arizona. At least thirty-six additional pairs nest in Mexico. Although the nesting sites are occupied, the tissues of the peregrine?s prey species still contain high concentrations of pesticides....
