A computer program for sample size computations for banding studies
K.R. Wilson, J.D. Nichols, J.E. Hines
1989, Fish and Wildlife Technical Report No. 23
Sample sizes necessary for estimating survival rates of banded birds, adults and young, are derived based on specified levels of precision. The banding study can be new or ongoing. The desired coefficient of variation (CV) for annual survival estimates, the CV for mean annual survival estimates, and the...
Temporal and geographic estimates of survival and recovery rates for the mallard, 1950 through 1985
Diane S. Chu, J.B. Hestbeck
1989, Fish and Wildlife Technical Report No. 20
Estimates of survival and recovery rates and the corresponding sample variances and covariances were made for mallards (Anas platyrhychos) banded before the hunting season for the period 1950-85. Estimates were made for adults and young, males and females, for as many banding reference areas as possible using standard band-recovery...
Atrazine Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
R. Eisler
1989, Contaminant Hazard Reviews Report 18 ; Biological Report 85(1.18)
The herbicide atrazine (2chloro4ethylamino6isopropylamino1,3,5triazine) is the most heavily used agricultural pesticide in North America. Domestically, more than 50 million kg are applied yearly to more than 25 million ha, primarily to control weeds in corn and sorghum crops. Atrazine residues have been detected in runoff from treated fields in lakes...

Pentachlorophenol Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
R. Eisler
1989, Contaminant Hazard Reviews Report 17 ; Biological Report 85(1.17).
Pentachlorophenol (PCP) is now widely used as a wood preservative, and this has contributed to the detection of PCP residues in air, rain, groundwaters, surface waters, fish and aquatic invertebrates, and in human urine, blood, and milk of nursing mothers. This report briefly reviews the technical literature on ecological...

1989, Book chapter, Proceedings of the 1989 Northeastern Recreation Research Symposium, April 3-5, 1989, Saratoga Springs, NY. ,
Recreational trespass on private lands within the Upper Delaware Scenic and Recreational River, located along the eastern border between Pennsylvania and New York, prompted this survey of recreational trespass sites. The National Park Service has been mandated to manage river recreational use within its boundaries but land ownership shall...
Turkey vulture and California condor

Beth Giron Pendleton, editor(s)
1989, Book chapter, Proceedings of the Western Raptor Management Symposium and Workshop.
Populations of turkey vultures in the western states appear stable, with no evidence of recent significant changes in distribution. Turkey vultures occupy a variety of habitats, nest in diverse situations and utilize a wide variety of carrion. Consequently, no particular limiting factor is likely to have a major...
Snowy owl

1989, Book chapter, Proceedings of the Northeast Raptor Management Symposium and Workshop.
The snowy owl is a rare to uncommon, irregular winter visitor in the northeastern United States, decreasing southward in abundance except during incursion years, when it is more common and widely distributed. Although snowy owls are recorded in northern New England every winter, major incursions occur at approximately three...
Monitoring bird populations with Breeding Bird Survey and atlas data

The principal means of monitoring avian species in North America since 1966 is the Breeding Bird Survey (BBS). Nearly 2000 random roadside rouleS of 50 3-minule stops each are run once each summer by experienced observers. Two-year and 10ng-lerm population trends have been calculated for 250 of the more common...

The shiny cowbird (Molthrus bonariensis), an avian brood parasite, is endemic to South America, Trinidad, and Tobago, but during the last 100 years the species has spread through the West Indies. Successful colonization by the shiny cowbird depends on the availablitiy of suitable habitats and host species. As...

Various problems were identified with standardized hawk count data as annually collected at six sites. Some of the hawk lookouts increased their hours of observation from 1979-1985, thereby confounding the total counts. Data recording and missing data hamper coding of data and their use with modern analytical techniques....

1989, Book chapter, Disease and Threatened Birds
The whooping crane (Grus americana), although never abundant in North America, became endangered primarily because of habitat modification and destruction. To help recovery, a captive propagation and reintroduction program was initiated at the Patuxent Wildlife Research Center (PWRC) in 1966. However, in 1984, 7 of 39 whooping cranes...
