The influence of diet composition upon growth and development of Sandhill Cranes
John A. Serafin
1982, Condor (84) 427-434
Experiments were conducted to evaluate the effect of protein, metabolizable energy, and sulfur amino acid content of five diets upon growth and development of captive Florida Sandhill Crane (Grus canadensis pratensis) and Greater Sandhill Crane (G. c. tabida) chicks raised under controlled conditions. A high protein (32%) diet resulted...
Reduced mortality among young endangered masked bobwhite quail fed oxytetracycline-supplemented diets
John A. Serafin
1982, Avian Diseases (26) 422-425
Two experiments were conducted to examine the effect of oxytetracycline-supplemented diets on mortality of young endangered masked bobwhite quail (Colinus virginianus ridgwayi). Inclusion of oxytetracycline at 200 g per ton in the feed for 6 weeks resulted in a marked, significant reduction in mortality of young masked bobwhite quail raised...
Oviposition and the plasma concentrations of LH, progesterone, and corticosterone in bobwhite quail (Colinus virginianus) fed parathion
Barnett A. Rattner, L. Sileo, C.G. Scanes
1982, Journal of Reproduction and Fertility (66) 147-155
Bobwhite quail were fed concentrations of parathion (0,50, 100, 200 or 400 p.p.m.) for 10 days. Food intake, body weight change, brain acetylcholinesterase activity, egg production, and ovary weight were reduced in a dose-dependent manner. In a second experiment, birds were fed 0, 25 or 100 p.p.m. parathion...
Shotshell and shooter effectiveness: Lead vs. steel shot for duck hunting
D.D. Humburg, S.L. Sheriff, P.H. Geissler, T. Roster
1982, Wildlife Society Bulletin (10) 121-126
Shooter and shotshell effectiveness were tested during the 1979 waterfowl season at the Schell-Osage Wildlife Management Area (WMA), Missouri. Hunters who participated in the study bagged 1,967 ducks with 10,587 shots. No significant differences in bagging, crippling, or missing rates were measured among 4 Winchester 12 gauge loads: #4 buffered...
Diagnosis of anticholinesterase poisoning in birds: Effects of environmental temperature and underfeeding on cholinesterase activity
Barnett A. Rattner
1982, Environmental Toxicology and Chemistry (1) 329-335
Brain cholinesterase (ChE) activity has been used extensively to monitor exposure to organophosphorus (OP) and carbamate (CB) insecticides in wild birds. A series of factorial experiments was conducted to assess the extent to which noncontaminant-related environmental conditions might affect brain ChE activity and thereby confound the diagnosis of OP and...
A field evaluation of frogs as a potential source of secondary organophosphorus insecticide poisoning
G.V.N. Powell, L.R. DeWeese, T. G. Lamont
1982, Canadian Journal of Zoology (60) 2233-2235
Because amphibians are relatively resistant to organophosphorus insecticides and can bioaccumulate residues to high levels, they may be a source of secondary poisoning for vertebrates that feed on them. This hypothesis was tested by determining residues in breeding upland chorus frogs Pseudacris triseriata, that were collected from ponds treated...
Social organization in a nesting population of eastern willets (Catoptrophorus semipalmatus)
M.A. Howe
1982, The Auk (99) 88-102
The breeding ecology of eastern Willets (Catoptrophorus semipalmatus) was studied over a 3-yr period in a salt marsh on the Atlantic coast of Virginia. During the study, 171 adults were color-marked. Willets are strictly monogamous and show strong site and mate fidelity from year to year. Normally a pair bond...
Capturing birds with mist nets: A review
B.E. Keyes, C.E. Grue
1982, North American Bird Bander (7) 2-14
Herein we have tried to provide a comprehensive review of mist-netting techniques suitable for both novice and experienced netters. General mist-netting procedures and modifications developed by netters for particular bird species and habitats are included. Factors which influence capture success, including site selection, net specifications and placement, weather, and time...
Seasonal brain acetylcholinesterase activity in three species of shorebirds overwintering in Texas
C. A. Mitchell, Donald H. White
1982, Bulletin of Environmental Contamination and Toxicology (29) 360-365
There was no seasonal variation in average brain AChE activity for the 3 species of wild birds collected between October and February. Further work needs to be done, however, covering an even broader time frame which includes the reproductive cycle. It appears that some birds feeding at the mouth of...
A rapid field techniques for preparing ant chromosomes for karyotypic analysis
Patricia Mehlhop, A. L. Gardner
1982, Stain Technology (57) 99-101
This technique for chromosomal preparation of ant tissues for karyotypic analysis is advantageous under field conditions because it reduces processing time and can be used under humid conditions. The cerebral ganglia from prepupae or early pupae are incubated 20 minutes in a hypotonic citrate solution, minced in a fixative solution...
Sea turtle distribution along the boundary of the Gulf Stream current off eastern Florida
W. Hoffman, T. H. Fritts
1982, Herpetologica (38) 405-409
Aerial surveys, out to 222 km off the east coast of central Florida during August 1980, revealed that marine turtles were distributed in a narrow zone west of the Gulf Stream. Of 255 loggerhead turtles, Caretta caretta, only three were observed east of the western boundary of the Gulf...

Embryotoxic and biochemical effects of waste crankcase oil on birds' eggs
D. J. Hoffman, W. C. Eastin Jr., M. L. Gay
1982, Toxicology and Applied Pharmacology (63) 230-241
Waste crankcase oil (WCO) is a major source of oil pollution in both the aquatic and terrestrial environment and has been implicated in the poisoning of mammals and fish. It is also mutagenic. Since birds' eggs are highly sensitive to external microliter applications of environmentally polluting oils, we examined the...
Pharmacokinetics and tissue concentrations of tylosin in selected avian species
D. Locke, M. Bush, J. W. Carpenter
1982, American Journal of Veterinary Research (43) 1807-1810
Tissue and plasma concentrations and the biological half-life of tylosin in avian species of a variety of body sizes and metabolic rates were studied. The species chosen were eastern bobwhite quail (Colinus virginianus virginianus), pigeons (Columba livia), greater sandhill cranes (Grus canadensis tabida), and emus (Dromaius novaehollandiae). In the 1st...
Lead shot incidence in sediments and waterfowl gizzards from Merrymeeting Bay, Maine
J. R. Longcore, P.O. Corr, H.E. Spencer Jr.
1982, Wildlife Society Bulletin (10) 3-10
Lead shot in bottom sediments from Merrymeeting Bay, Maine, averaged 99,932 shot/ha. More shot (P < 0.05) was present in silt sediments than in sand sediments. Number 6 size shot was the most abundant in all 6 river deltas sampled. Ingested lead shot occurred in gizzards of...
Short-term effects of oil ingestion on American kestrels (Falco sparverius)
O. H. Pattee, J. C. Franson
1982, Journal of Wildlife Diseases (18) 235-241
The Mexican Ixtoc oil well blowout resulted in extensive oil contamination along the Texas Gulf coast. This oil posed a potential hazard to migrating birds including the endangered peregrine falcon (Falco peregrinus). Laboratory tests with the American kestrel (Falco sparverius) indicated that the oil: water mixture gathered at the surface...
Food habits of diving ducks in the Carolinas
Matthew C. Perry, F.M. Uhler
1982, Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies (36) 492-504
Food habits analyses were conducted on 264 diving ducks (7 species) from North and South Carolina during the 1970'S. The Baltic clam (Macoma balthica) was the predominant food among canvasbacks (Aythya valisineria) from the Pamlico River area, whereas sago pondweed (Potamogeton pectinatus) predominated in birds from impoundments in North...

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...
