Bird specimens and documentation: Critical data for a critical resource
M.S. Foster, P. Cannell
1990, Condor (92) 277-283
As governments impose increasingly stringent regulations on the collection of bird specimens and as man alters ever greater areas of habitat with the loss of many of their contained species, museum specimens increase immeasurably in importance. Yet at present, museum collections do not contain an adequate representation of the...
Factors influencing bird foraging preferences among conspecific fruit trees
M.S. Foster
1990, Condor (92) 844-854
The rates at which birds visit fruiting individuals of Allophylus edulis (Sapindaceae) differ substantially among trees. Such avian feeding preferences are well-known, but usually involve fruits and trees of different species. Factors controlling avian preferences for particular trees in a population of conspecifics are generally undocumented. To address this issue,...
Lead and cadmium concentrations in mink from northern Idaho
L. J. Blus, Charles J. Henny
1990, Northwest Science (64) 219-223
The purposes of this study were to determine concentrations of cadmium and lead in mink (Mustela vison) in northern Idaho, to discuss potential effects, and to determine whether levels have declined. Mink (skinned carcasses) from the Coeur d'Alene River system (northern Idaho) were ohtained from trappers during the 1981-82 (n...
Evidence for a fall raptor migration pathway across the South China Sea
D. H. Ellis, A.K. Kepler, C. B. Kepler
1990, Journal of Raptor Research (24) 12-18
While conducting seabird surveys along the cruise track of the Soviet oceanographic Research Vessel Akademlk Korolev in the South China Sea in late October, 1988, we encountered about 150 land birds, including about 40 raptors. Most of the raptors were small accipiters, but we also recorded small numbers of Peregrine...
Trace elements in soil and biota in confined disposal facilities for dredged material
W. N. Beyer, G. Miller, J.W. Simmers
1990, Environmental Pollution (65) 19-32
We studied the relation of trace element concentrations in soil to those in house mice (Mus musculus), common reed (Phragmites australis) and ladybugs (Coccinella septempunctata) at five disposal facilities for dredged material. The sites had a wide range of soil trace element concentrations, acid soils and a depauperate fauna....
Dicofol (Kelthane®)-induced eggshell thinning in captive american kestrels
D. R. Clark Jr., J. W. Spann, C.M. Bunck
1990, Environmental Toxicology and Chemistry (9) 1063-1069
Reproductive parameters of American kestrels (Falco sparverius) were measured through two breeding seasons. Exposure to Kelthane® (containing no DDT-related compounds) at dietary concentrations of 0 (control), 1,3, 10 and 30 μg/g (wet weight) began in late November before, and continued through, the second season. Kelthane thinned eggshells and lowered the...
Flexible models for analysing ring recovery data to estimate survival rates
M.J. Conroy, J.E. Hines
1990, Ring (13) 173-192
We describe MULT, a flexible procedure for analysing ring recovery data. The procedure starts with parametric structures similar to, but more general than, those described by Brownie et al. (1985). Particular models, including those in Brownie et al. (1965), can be obtained by imposing constraints on the general parametric structures....
Effects of arsenate on growth and physiology in mallard ducklings
M.B. Camardese, D. J. Hoffman, L. J. LeCaptain, G.W. Pendleton
1990, Environmental Toxicology and Chemistry (9) 785-795
Arsenic (As) has been found at elevated concentrations in irrigation drainwater and in aquatic plants utilized by waterfowl. Mallard (Anas platyrhynchos) ducklings received an untreated diet (controls) or diets containing 30, 100 or 300 ppm As added as sodium arsenate. After 10 weeks blood and tissue samples were collected for...
Raptor road surveys in South America
D. H. Ellis, R.L. Glinski, D.G. Smith
1990, Journal of Raptor Research (24) 98-106
Twenty-six (23 traveling and three point) raptor roadside surveys were conducted during a 29,000 km expedition through nine nations of South America. During roadside surveys, we tallied 41 of the 87 (47%) diurnal raptor species (including vultures) that occur in South America. The number of species observed per route varied...
[Book review] Ospreys: A natural and unnatural history
Charles J. Henny
1990, The Auk (107) 808-809
The Osprey (Pandion haliaetus) is now arguably the world's best known bird of prey. The DDT-related Osprey population crash in the northeastern United States resulted in an unparalleled amount of research during the last 20 years. In 1969, when I published my first paper on Ospreys in The Auk, there...
[Book review] Return of the Whooping Crane
D. H. Ellis, D.G. Smith
1990, The Auk (107) 812-814
Fewer than 40 years ago, Life magazine ran an article decrying the plight of Whooping Cranes (Grus americana) on their wintering grounds at Aransas National Wildlife Refuge (Aransas) along the Gulf Coast. The small flock of approximately 20 birds that summered at Wood Buffalo National Park (Wood Buffalo) in Canada...

Environmental contaminant concentrations in biota from the lower Savannah River, Georgia and South Carolina
P. V. Winger, D.P. Schultz, W.W. Johnson
1990, Archives of Environmental Contamination and Toxicology (19) 101-117
Planned harbor expansion and industrial developments may adversely affect the economically important aquatic resources of the lower Savannah River, including those at the Savannah National Wildlife Refuge. To establish the present level of chemical contamination in this system, we collected a total of 102 samples of nine species of fish...
Survival of northern bobwhites in Georgia: Cropland use and pesticides
Donald H. White, J.T. Seginak, R.C. Simpson
1990, Bulletin of Environmental Contamination and Toxicology (44) 73-80
At the end of 18 weeks during spring and summer in 1986 and 1987, survival was 0.5339 and 0.3709 respectively. Repeated organophosphorus insecticide sprays to crops in 1987 may have significantly reduced survival of bobwhites beyond that seen in 1986 when few pesticides were applied. Cropland use was...

1990, Journal of Wildlife Diseases (26) 103-106
Brain cholinesterase (ChE) activities of songbirds collected in pecan groves 6 to 7 hr after separate applications of the organophosphorus pesticides, phosalone and disulfoton, were compared to mean ChE activities of controls (normals) as a measure of insecticide exposure. In general, reduction of...

1990, Environmental Pollution (65) 169-180
Small mammals were trapped, tagged and recaptured in 0·45 ha plots at six hazardous industrial waste disposal sites to determine if populations, body mass and age structures were different from paired control site plots. Low numbers of six species of small mammals were captured on industrial waste sites or control...

W.V. Sliter, I. Premoli-Silva
1990, Paleoceanography and Paleoclimatology (5) 639-667
Detailed planktonic foraminiferal biostratigraphy from eight measured sections of Cretaceous limestone near Laytonville, California, indicates a composite sequence that extends in age from late Albian to early Turonian. The sequence contains seven biozones and two subzones based on the first and last appearance datums of planktonic foraminifers examined in thin...
Statistical inference for capture-recapture experiments
Kenneth H. Pollock, James D. Nichols, Cavell Brownie, James E. Hines
1990, Book, Wildlife Monographs
This monograph presents a detailed, practical exposition on the design, analysis, and interpretation of capture-recapture studies. The Lincoln-Petersen model (Chapter 2) and the closed population models (Chapter 3) are presented only briefly because these models have been covered in detail elsewhere. The Jolly- Seber open population model, which...

Chlordane Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
R. Eisler
1990, Contaminant Hazard Reviews Report 21 ; Biological Report 85(1.21).
Technical chlordane is an organochlorine compound first introduced into the United States in 1947 in a variety of formulations for use as a broad-spectrum pesticide. By 1974, about 9.5 million kilograms of chlordane were produced annually. Concern over the potential carcinogenicity of chlordane has led to sharply curtailed...
Paraquat Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
R. Eisler
1990, Contaminant Hazard Reviews Report 22 ; Biological Report 85(1.22)
Paraquat (1,1`dimethyl4,4`bipyridinium) are broad-spectrum contact plant killers and herbage desiccants that were introduced commercially during the past 25 years. Today, they rank among the most widely used herbicides globally and are frequently used in combination with other herbicides. The recommended paraquat field application rates for terrestrial weed control...
