Fifty-eighth Christmas Bird Count. 166. Ocean City, Md Fifty-eighth Christmas Bird Count. 166. Ocean City, Md
Gauging the impact of manipulative activities, such as rehabilitation or management, on wetlands requires having a notion of the unmanipulated condition as a reference. An understanding of the reference condition requires knowledge of dominant factors influencing ecosystem processes and biological communities. In this paper, we focus on natural physical factors (conditions and processes)...

Factors influencing estimation of pesticide-related wildlife mortality Factors influencing estimation of pesticide-related wildlife mortality
Free-ranging wildlife is regularly exposed to pesticides and can serve as a sentinel for human and environmental health. Therefore a comprehensive pesticide hazard assessment must incorporate the effects of actual applications on free-ranging wildlife. Mortality is the most readily reported wildlife effect, and the significance of these data can be realized only when placed in context...

Relative effects of plumage coloration and vegetation density on nest success Relative effects of plumage coloration and vegetation density on nest success
Many passerine species are highly dichromatic with brightly-colored males and cryptically-colored females. Bright plumage in males is commonly thought to arise as a result of sexual selection by females such that males with bright coloration possess high fitness. However, bright plumage potentially could expose males to increased predation risk. Consistent with this idea, males of many...

Marsh birds and the North American Breeding Bird Survey: judging the value of a landscape level survey for habitat specialist species with low detection rates Marsh birds and the North American Breeding Bird Survey: judging the value of a landscape level survey for habitat specialist species with low detection rates
The North American Breeding Bird Survey was started in 1966, and provides information on population change for >400 species of birds. it covers the continental United States, Canada, and Alaska, and is conducted once each year, in June, by volunteer observers. A 39.4 kIn roadside survey route is driven starting 30 min before sunrise, and a 3 min point count is conducted at each of 50...

Characterizing backcountry camping impacts in Great Smoky Mountains National Park Characterizing backcountry camping impacts in Great Smoky Mountains National Park
This investigates resource impacts on backcounty campsites in the Great Smoky Mountains National Park, USA. Study objectives were to enhance our understanding of camping impacts and to improve campsite impact assessment procedures by means of multivariate techniques. Three-hundred and eight campsites at designated backcountry campgrounds, and 69 additional unofficial campsites were...

Forest area and distribution in the Mississippi alluvial valley: Implications for breeding bird conservation Forest area and distribution in the Mississippi alluvial valley: Implications for breeding bird conservation
Knowing the current forest distribution and patch size characteristics is integral to the development of geographically defined, habitat-based conservation objectives for breeding birds. Towards this end, we classified 2.6 million ha of forest cover within the Mississippi Alluvial Valley using 1992 thematic mapper satellite imagery. Although historically this area, from southern Illinois...

Husbandry and care of quail Husbandry and care of quail
Both the Japanese and Bobwhite quail are important species for biomedical, toxicological and basic biological research. In view of their rapid maturation, high reproductive rate in captivity, and other physiological characteristics, these species have been and will continue to be used successfully as model avian species. This short reviews describes caging, environmental, and feed...
