Methods to evaluate habitat use by raptors
M.R. Fuller, B.R. Noon, J. A. Mosher
Wilbur N. Ladd, P.F. Schempf, editor(s)
1982, Book, Proceedings of a Symposium and Workshop: Raptor Management and Biology in Alaska and Western Canada
The peregrine falcon in Arizona: Habitat utilization and management recommendations
D. H. Ellis
1982, Institute for Raptor Studies Research Reports 1.
The peregrine falcon once bred in significant numbers in Arizona. Good documentation is available for specific breeding sites and an additional 20 general locations. This report, based on the published literature, an extensive personal contact survey, an aerial habitat inventory (over 124 hours air time), and ground visits to...
Assessment of some important factors affecting the singing-ground survey
J. Tautin
1982, Report, Woodcock ecology and management
A brief history of the procedures used to analyze singing-ground survey data is outlined. Some weaknesses associated with the analytical procedures are discussed, and preliminary results of efforts to improve the procedures are presented. The most significant finding to date is that counts made by new observers need...
Terrestrial animal species panel
R. Gerrits, G. Rabb, G. Gee, and others
1982, Book chapter, Proceedings of the U.S. Strategy Conference on Biological Diversity, November 16-18, 1981
Regional population inferences for the American woodcock
T.J. Dwyer, J.D. Nichols
1982, Book chapter, Woodcock Ecology and Management
Woodcock (Philohela minor) bandings and recoveries from 1967 to 1977 were analyzed from two large banding reference areas corresponding to existing Eastern and Central harvest units. We examined temporal, age-specific, sex-specific, and geographic variation in both survival and recovery rates, using recently developed stochastic models. Survival rate estimates...
Woodcock response to habitat management in Maine
G.F. Sepik, T.J. Dwyer
1982, Research Report 14
A study was initiated in 1975 at the Moosehorn National Wildlife Refuge to develop habitat management techniques for woodcock (Philohela minor) that could be used by small landowners as well as in commercial forestry operations. Use of selected diurnal covers by adult female and juvenile woodcock increased after strips...
Hormonal treatment and flight feather molt in immature Sandhill Cranes
G.F. Gee
J. C. Lewis, editor(s)
1982, Book chapter, Proceedings of the 1981 Crane Workshop
Molt, the production of a new generation of feathers, is a poorly understood physiological phenomenon in nondomestic birds. Often in large birds like geese, flight is restricted by clipping the primary remiges on 1 wing and flight is restored after the molt when the primaries are replaced. A similar technique...
Examination of woodcock nest sites in central Pennsylvania
R.A. Coon, B. Kenneth Williams, J.S. Lindzey, J.L. George
1982, Wildlife Research Report 14
Evidence is given to support Iow selectivity in choice of nest sites by woodcock (Philohela minor). Habitat characteristics measured at 30 woodcock nest sites were compared with non-nest control sites in Huntingdon County, central Pennsylvania. Mean nest density per year was 1/4.8 ha within the 54-ha study area. Of 14...
Modern pesticides and bobwhite populations
K. L. Stromborg
Frank= Schitoskey Jr., Elizabeth C. Schitoskey, Larry G. Talent, editor(s)
1982, Book chapter
Bobwhite (Colinus virginianus) are frequently used as test animals for wildlife tests of pesticides. The organophosphate and carbamate pesticides that have replaced the organochlorines have many desirable properties, but they span a wide range of acute toxicities and some of them affe,ct survival, reproduction, food consumption, behavior, and nervous system...
Subacute dietary toxicities of dicrotophos and dieldrin in time-replicated trials with young ring-necked pheasants and mallards
E. F. Hill
D.W. Lamb, E.E. Kenaga, editor(s)
1982, Book chapter, Avian and Mammalian Wildlife Toxicology: Second Conference
The dietary toxicities of (E)-phosphoric acid 3-(dimethylamino)-1-methyl-3-oxo-1-propenyl dimethyl ester (dicrotophos) and 3,4,5,6,9,9-hexachloro-1a,2,2a,3,6,6a,7,7a-octahydro-2,7:3,6-dimethanonaphth[2,3-b]oxirene (dieldrin) to 10-day-old ring-necked pheasants (Phasianus colchicus) and 5-day-old mallards (Anas platyrhynchos) were compared in five time-replicated trials. Toxicities were calculated as median lethal concentrations (LC50s) based on 5 days of ad libitum feeding on geometrically spaced concentrations...
Mourning Dove Nesting: Seasonal Patterns and Effects of September Hunting
P.H. Geissler, David D. Dolton, R.A. Coon, H.F. Percival, R. Field, D. W. Hayne, L.D. Soileau, R.R. George, J.H. Dunks, S.D. Bunnell
1982, Book
A nationwide State/Federal cooperative study was initiated in 1978 to examine effects of September hunting on mourning dove (Zenaida macroura) nesting. This study was designed to (1) determine the proportion of the annual total of dove nesting activity and production that occurs in September and October, and (2) determine if...
A.B.A. Checklist: Birds of Continental United States and Canada
G.S. Keith, L.G. Balch, D.D. Gibson, R.G. McCaskie, C.S. Robbins, A. Small, P.W. Sykes Jr., J.A. Tucker
1982, Book
The 'Summary' in this edition of the A BA Checklist has been greatly expanded to include all properly documented records for each accidental species. These records are published, except for a very few recent ones which are in press or in preparation. Emphasis is on records supported by...
