S. Haseltine, Gary L. Hensler
1981, Environmental Pollution (Series A) (25) 139-147
Mallard ducklings (Anas platyrhynchos) were exposed to a 13-day dietary treatment of 0, 0·5 or 5·0 ppm phosphamidon at one of three successive age intervals (5–17 days, 18–30 days, or 31–43 days) during a 10-week growth period. Weekly measurements of body weight, wing length, primary feather length, and bill length...

Iatrogenic salt poisoning in captive sandhill cranes
J. C. Franson, L. Sileo, W. James Fleming
1981, Journal of the American Veterinary Medical Association (179) 1211-1213
Salt poisoning developed in captive sandhill cranes (Grus canadensis) when sea salt was added to normal drinking water to produce a sodium chloride concentration of 1%. Two of 18 cranes died and 2 were euthanatized when moribund. Muscle weakness, paresis, dyspnea, and depression were observed. Brain and serum sodium, serum...

Importance of structural stability to success of mourning dove nests
R.A. Coon, J.D. Nichols, H.F. Percival
1981, The Auk (98) 389-391
Studies of nest-site selection and nesting habitats often involve a "characterization" of nests and of habitats in which nests are found. Our objective in the present work is to identify nest-site characteristics that are associated with variation in components of Mourning Dove (Zenaida macroura) fitness (e.g. the probability of a...
Colony site dynamics and habitat use in Atlantic coast seabirds
R.M. Erwin, J. Galli, J. Burger
1981, The Auk (98) 550-561
Seabird colony sizes and movements were documented in the DelMarVa coastal region in 1976-1977 and in New Jersey in 1978-1979. Most colonies were found on marsh and dredge deposition islands and on barrier island beaches. For the "traditionally" beach-nesting Herring Gull, Common Tern, and Black Skimmer, larger, more stable colonies...
Marine turtles of the Galapagos Islands and adjacent areas of the eastern Pacific on the basis of observations made by J.R. Slevin 1905-1906
T. H. Fritts
1981, Journal of Herpetology (15) 293-301
The field notes of J. R. Slevin written during the expedition of the California Academy of Sciences to the Galapagos Islands in 1905-1096 contain previously unavailable data on the marine turtles of the eastern Pacific. 'Land basking' by green turtles in Galapagos was predominately, if not exclusively, a female behavior....
Censusing wading bird colonies: An update on the 'flight-line' count method
R.M. Erwin
1981, Colonial Waterbirds (4) 91-95
1. Thirteen mixed-species heronries (10 in Florida, two in Virginia, one in North Carolina) were studied in 1980 as part of a project begun in 1979 aimed at evaluating the 'flight-line' census method..2. Standardized counts of Snowy and Cattle Egrets, Louisiana and Little Blue Herons flying to and from the...
Pharmocokinetics of cephalothin and cephalexin in selected avian species
M. Bush, D. Locke, L.A. Neal, J. W. Carpenter
1981, American Journal of Veterinary Research (42) 1014-1017
Plasma concentrations and the biological half-lives of cephalothin and cephalexin in avian species of a variety of body sizes and metabolic rates were studied. The species chosen were eastern bobwhite quail (Colinus v virginianus), pigeons (Columba livia), hybrid rosybill ducks (Netta sp), greater sandhill cranes (Grus canadensis tabida), and emus...
Gentamicin tissue concentration in various avian species following recommended dosage therapy
M. Bush, D. Locke, L.A. Neal, J. W. Carpenter
1981, American Journal of Veterinary Research (42) 2114-2116
Plasma and tissue drug concentrations were compared in eastern bobwhite quail (Colinus virginianus virginianus) and pigeons (Columba livia) given gentamicin by IM administration at the dosage of 10 mg/kg, and in greater sandhill cranes (Grus canadensis tabida) and hybrid rosybill ducks (Netta sp) given the same antibiotic at a dosage...

Nationwide residues of organochlorine compounds in wings of adult mallards and black ducks, 1979-80
B. W. Cain
1981, Pesticides Monitoring Journal (15) 128-134
Organochlorine residues in wings of adult mallards (Anas platyrhynchos) and black ducks (Anas rubripes) were monitored nationwide from birds harvested during the 1979-80 hunting season. DDE residues were found in all samples. DDT residues had declined from levels reported in 1976 on a flyway basis but the decline was significant...
Studies on the riboflavin, pantothenic acid, nicotinic acid and choline requirements of young Embden geese
John A. Serafin
1981, Poultry Science (60) 1910-1915
Four experiments were conducted to examine the riboflavin, pantothenic acid, nicotinic acid, and choline requirements of young Embden geese fed purified diets. Goslings fed diets deficient in either riboflavin, pantothenic acid, nicotinic acid, or choline grew poorly. Feeding a pantothenic acid-deficient diet resulted in 100% mortality. Goslings fed diets containing...
Organochlorine and metal residues in eggs of waterfowl nesting on islands in Lake Michigan off Door County, Wisconsin, 1977-78
S. D. Haseltine, G. H. Heinz, W. L. Reichel, John F. Moore
1981, Pesticides Monitoring Journal (15) 90-97
One egg from each of 114 red-breasted merganser (Mergus serrator) nests in 1977 and 92 nests in 1978 was collected and later analyzed for organochlorines, polybrominated biphenyls (PBBs), polychlorinated styrenes (PCSs). and metals. One egg was also collected from each of the dabbling duck nests located: Twenty-nine of...
Embryotoxic effects of benzo[a]pyrene, chrysene and 7,12-dimethylbenz[a]-anthracene in petroleum hydrocarbon mixtures in mallard ducks
D. J. Hoffman, M. L. Gay
1981, Journal of Toxicology and Environmental Health (7) 775-787
Studies with different avian species have revealed that surface applications of microliter amounts of some crude and fuel oils that coat less than 70% of the egg surface result in considerable reduction in hatching with teratogenicity and stunted growth. Other stUdies have shown that the embryo toxicity is dependent...
Recovery of cholinesterase activity in mallard ducklings administered organophosphorus pesticides
W. James Fleming, S.P. Bradbury
1981, Journal of Toxicology and Environmental Health (8) 885-897
Oral doses of the organophosphorus pesticides acephate, dicrotophos, fensulfothion, fonofos, malathion, and parathion were administered to mallard ducklings (Anas platyrhynchos), and brain and plasma cholinesterase (ChE) activities were determined for up to 77 d after dosing. In vivo recovery of brain ChE activity to within 2 standard deviations of the...

W. James Fleming, E. Cromartie
1981, Pesticides Monitoring Journal (14) 115-118
Breast muscle DDE residues were as high as 5.8 ppm wet-weight basis and 280 ppm lipid-weight basis in young wood ducks (Aix Sponsa) collected on Wheeler National Wildlife Refuge near a former DDT manufacturing plant in northern Alabama.

Organochlorine residues and mortality of herons
Harry M. Ohlendorf, Douglas M. Swineford, Louis N. Locke
1981, Pesticides Monitoring Journal (14) 125-135
Since 1966, 72 herons found dead or moribund in the field have been analyzed for organochlorine chemicals. In addition, 36 herons were obtained through systematic collections, and carcasses were analyzed to determine sublethal exposure to organochlorines. Brains of birds found dead or moribund were analyzed to determine whether the birds...
