Eggshell modifications in captive American kestrels resulting from Aroclor 1248 in the diet Eggshell modifications in captive American kestrels resulting from Aroclor 1248 in the diet
American kestrels (Falco sparverius) were fed diets containing 3 μg/g Aroclor® 1 1248 or control diets from mid-January until July. Eggs were removed from first clutches 2 to 4 days after laying ceased and shell thickness and shell dimensions were measured. Contents of the third egg of each clutch, the carcasses of all adults that received Aroclor® 1248 and of three males and three...

Trace elements and organochlorines in surf scoters from San Francisco Bay, 1985 Trace elements and organochlorines in surf scoters from San Francisco Bay, 1985
Surf scoters (Melanitta perspicillata) were collected from 6 locations in San Francisco Bay during January and March 1985. Overall, mean concentrations of cadmium and zinc were higher in livers of scoters from the southern region of the Bay, whereas mean iron and lead were higher in those from the northern Bay region. Mean concentrations of arsenic, copper, lead, zinc, aluminum (January...

Effects of maternal and grandmaternal nutrition on deer mass and vulnerability to wolf predation Effects of maternal and grandmaternal nutrition on deer mass and vulnerability to wolf predation
In a Minnesota ecosystem, mass of female white-tailed deer (Odocoileus virginianus) fawns and adults, and survival of adult females in the face of wolf (Canis lupus) predation, were directly related to maternal nutrition during gestation. Mass of single male fawns produced by 2-year-old females, and survival of yearlings to 2 years of age were related directly to the nutrition of their

Factors affecting winter distribution and migration distance of wood ducks from southern breeding populations Factors affecting winter distribution and migration distance of wood ducks from southern breeding populations
We used direct band-recovery records of Wood Ducks (Aix sponsa) banded 1 April-15 September (1960-1987) in the southern and southeastern reference areas of Bowers and Martin (1975) to test whether winter distribution and migration distance were age- and sex-specific. Effects of variation in early-autumn temperature and precipitation conditions on winter distribution patterns also were...

Methods for control of tick vectors of Lyme Borreliosis Methods for control of tick vectors of Lyme Borreliosis
During the IVth International Conference on Lyme Borreliosis in Stockholm, 1990, a workshop on control of Lyme disease vectors briefly reviewed: basic ecological principles for tick control; biocontrol of ticks; chemical control, including the use of repellents and use of permethrin-treated rodent nest material; tick control by habitat modification; and reduction of tick host...

Introgression of coyote mitochondrial DNA into sympatric North American gray wolf populations Introgression of coyote mitochondrial DNA into sympatric North American gray wolf populations
Mitochondrial DNA (mtDNA) genotypes of gray wolves and coyotes from localities throughout North America were determined using restriction fragment length polymorphisms. Of the 13 genotypes found among the wolves, 7 are clearly of coyote origin, indicating that genetic transfer of coyote mtDNA into wolf populations has occurred through hybridization. The transfer of mtDNA appears...

Flight restraint techniques for captive cranes Flight restraint techniques for captive cranes
Traditional techniques for preventing escape of captive cranes (i.e., tenotomy, tenectomy, wing clipping, confinement under nets, and amputation) are discussed briefly. Two additional techniques (i.e., brailing and vane trimming) are described in detail. The advantages and limitations of each technique are presented.

Past and potential contributions of captive breeding to population recovery of the Whooping Crane Past and potential contributions of captive breeding to population recovery of the Whooping Crane
A captive Whooping Crane colony was established at the Patuxent Wildlifa Research Center in Maryland in 1966. This colony first produced eggs in 1975 and has produced 252 eggs through 1990. From 1976 to 1984, 73 eggs were sent Io Grays Lake, Idaho, the site of the first Whooplng Crane reintroduction attempt. Canada also provided 216 eggs (1976-1988) from the wild population. Although 84...
