Responses of the iguanid lizard Anolis carolinensis to four organophosphorus pesticides
R.J. Hall, D. R. Clark Jr.
1982, Environmental Pollution (Series A) (28) 45-52
Dose related mortality and cholinesterase effects of parathion, methyl parathion, azinphos-methyl and malathion on Anolis carolinensis were investigated. The comparative effects of the four compounds on fish, birds and mammals are well known, but the effects of organophosphates on reptiles have not been studied critically. Sensitivity and patterns of mortality from exposure...
Nesting by one-year-old black-crowned night herons on Hope Island, Rhode Island
Thomas W. Custer, William E. Davis Jr.
1982, The Auk (99) 784-786
There have been few consistent reports concerning the frequency and success of nesting attempts by immature night herons of the genus Nycticorax. One- year-old Black-crowned Night Herons (Nycticorax nycticorax) mated to 2-yr-old or older birds built nests and incubated eggs in the wild (Gross 1923). In a captive colony, many...
Observer variability in estimating numbers: An experiment
R.M. Erwin
1982, Journal of Field Ornithology (53) 159-167
Census estimates of bird populations provide an essential framework for a host of research and management questions. However, with some exceptions, the reliability of numerical estimates and the factors influencing them have received insufficient attention. Independent of the problems associated with habitat type, weather conditions, cryptic coloration, ete.,...
Estimating reproductive success in colonial waterbirds: An evaluation
R.M. Erwin, T. W. Custer
1982, Colonial Waterbirds (5) 49-56
To estimate reproductive success in a population one ideally would like to determine the number of young fledged per nesting female. However, this is difficult because often (1) the adults are not individually marked, (2) the colony is not visited daily, and (3) the investigator is unable to monitor...

Effects of a chemical dispersant and crude oil on breeding ducks
P.H. Albers, M. L. Gay
1982, Bulletin of Environmental Contamination and Toxicology (29) 404-411
Effects of chemically dispersed crude oil on mallard reproduction. Incubating female mallards were exposed to a water source treated with either Prudhoe Bay crude oil, Corexit 9527, or a combination of oil and dispersant during the first 10 da of development. Used thermocouple probes to monitor incubation temperature....

Further interpretation of the relation of organochlorine residues in brown pelican eggs to reproductive success
L. J. Blus
1982, Environmental Pollution (Series A) (28) 15-33
This study was conducted to provide additional interpretation of the relation of organochlorine pollutants to reproductive success and population stability of brown pelicans Pelecanus occidentalis in the southeastern United States from 1969 to 1977. The sample egg technique was employed in South Carolina; it involved collecting an egg from each of 156...
Inclusion body hepatitis in kestrels (Falco sparverius)
L. Sileo, J. C. Franson, D.L. Graham, C.H. Domermuth, Barnett A. Rattner, O. H. Pattee
1982, Conference Paper, Wildlife Disease Association Conference Proceedings
Inclusion body disease of suspected adenovirus etiology was the apparent cause of death of 9 captive kestrels (Falco sparverius). Cloacal hemorrhage was the only prominent gross lesion; disseminated hepatocellular necrosis and intranuclear inclusion bodies were evident microscopically. Attempts to reproduce the disease, and to propagate and serologically characterize...
Inorganic and organic mercury chloride toxicity to Coturnix: Sensitivity related to age and quantal assessment of physiologic responses
E. F. Hill
1982, Dissertation Abstracts International (43) 57B-58B(abs)
The toxicities of mercuric chloride (HgCl(,2)) and methylmercuric chloride (CH(,3)HgCl) were compared for coturnix (Coturnix coturnix japonica) from hatching to adulthood. Comparisons were based on: (1) Median lethal dosages (LD50) derived by administering single peroral and single intramuscular dosages of mercury, (2) median lethal concentrations (LC50) derived by feeding mercury...

Organophosphate inhibition of avian salt gland Na, K-ATPase activity
W. C. Eastin Jr., W. James Fleming, H. C. Murray
1982, Comparative Biochemistry and Physiology, Part C: Comparative Pharmacology (73) 101-107
1. Adult black ducks (Anas rubripes) were given freshwater or saltwater (1.5% NaCl) for 11 days and half of each group was also given an organophosphate (17 p.p.m. fenthion) in the diet on days 6–11.2. After 11 days, ducks drinking saltrwater had lost more weight and had higher plasma Na...
Ecology of avian brood parasitism at an early interfacing of host and parasite populations
J. W. Wiley
1982, Dissertation Abstracts International (43) 973-B(abs)
The shiny cowbird (Molothrus bonariensis), a brood parasite, has recently spread into the Greater Antilles from South America via the Lesser Antilles. This species is a host generalist and upon reaching Puerto Rico exploited avian communities with no history of social parasitism. Forty-two percent of the resident non-raptorial land bird...

Organophosphate insecticide poisoning of Canada geese in the Texas panhandle
Donald H. White, C. A. Mitchell, L.D. Wynn, Edward L. Flickinger, E. J. Kolbe
1982, Journal of Field Ornithology (53) 22-27
Sixteen hundred waterfowl, mostly Canada Geese, died near Etter, Texas, in late January 1981 from anticholinesterase poisoning. Winter wheat in the area of the die-off had been treated with organophosphate insecticides to control greenbugs. Cholinesterase (ChE) levels in brains of a sample of geese found dead were 75%...
Care of nestlings by wild female starlings exposed to an organophosphate pesticide
C.E. Grue, G.V.N. Powell, M.J. McChesney
1982, Journal of Applied Ecology (19) 327-335
(1) Our objective was to determine the effect of exposure to an organophosphate pesticide (OP), dicrotophos (3-hydroxy-N,N-dimethyl-cis-scrotonamide dimethyl phosphate), on care of nestlings by wild female starlings (Sturnus vulgaris).(2) We selected twelve pairs of active nests based on synchrony in the reproductive cycle. When nestlings were 10 days old (day...
Influence of protein level and supplemental methionine in practical rations for young endangered masked bobwhite quail
John A. Serafin
1982, Poultry Science (61) 988-990
A study was conducted to examine the protein requirement of young endangered masked Bobwhite quail (Colinus virginianus ridgwayi). Five practical starting rations containing 24 to 32% protein were fed alone and supplemented with methionine for 5 weeks. Supplemental methionine significantly improved growth of quail fed diets containing 24...
Influence of dietary protein and excess methionine on choline needs for young bobwhite quail
John A. Serafin
1982, Poultry Science (61) 902-908
Experiments were conducted with young Bobwhite quail (Colinus virginianus) to investigate the effect of differing dietary protein levels and nondetrimental amounts of excess methionine on choline needs. Growth and feed consumption of quail fed an adequate (27.3%) protein purified diet supplemented with 2000 mg/kg of choline were unaffected by increasing...

1982, Water-Resources Investigations Report 82-350
The Loxahatchee River estuary empties into the Atlantic Ocean at Jupiter Inlet in southeastern Florida. Although relatively small, the estuary is important for its esthetic value and for its sport fishing, boating, recreation, tourism, and prime residential development. In recent years, the condition of the estuary has become of concern...
Wolf depredation on livestock in Minnesota
S. H. Fritts
1982, Resource Publication 145
Depredation by wolves (Canis lupus) on cattle, sheep, and other livestock in Minnesota currently is a minor problem except to a few individual farmers. Indices to the seriousness of the problem are available only from recent years, so historical trends cannot be detected. From 1976 through 1980 the number of...

This is the seventh in a series of comprehensive reports on population ecology of the mallard (Anas platyrhynchos) in North America. Banding records for 1961-1975 were used, together with information from previous reports in this series, to estimate annual and average preseason age and sex structure of the mallard...
