Longevity records of North American birds: Coerebinae through Estrildidae Longevity records of North American birds: Coerebinae through Estrildidae
This is the fourth paper of a 4-part series detailing the longevity records of marked North American birds. The previous three papers can be found in the Journal of Field Ornithology, Volumes 53 and 54. Prio to this series only one definitive paper ( Kennard 1975) had been written on North American taxa. Records for 84 taxa are included in this paper. Thirty are birds older than those...

Improving atlas methodology Improving atlas methodology
We are studying a sample of Maryland (2 %) and New Hampshire (4 %) Atlas blocks and a small sample in Maine. These three States used different sampling methods and block sizes. We compare sampling techniques, roadside with off-road coverage, our coverage with that of the volunteers, and different methods of quantifying Atlas results. The 7 1/2' (12-km) blocks used in the Maine Atlas are

Checklist of vertebrates of the United States, the U.S. territories, and Canada Checklist of vertebrates of the United States, the U.S. territories, and Canada
On 30 January 1980 the Policy Group of the 1978 Interagency Agreement on Classifications and Inventory established a work group on fish and wildlife species names. The participating agencies were the Fish and Wildlife Service, Forest Service, Bureau of Land Management, Geological Survey, and Soil Conservation Service. The Fish and Wildlife Service was assigned the role of establishing...

Relationships between nesting populations of wading birds and habitat features along the Atlantic Coast Relationships between nesting populations of wading birds and habitat features along the Atlantic Coast
Using previously published atlas data for 122 mixed-species wading bird colonies on islands along the Atlantic coast (Maine to Florida, 1976-77), we examined relationships between population sizes of 11 species of egrets, herons, ibises, and wood storks (Mycteria americana) and nine habitat variables. On nautical charts, we measured four island characteristics (area, length, width, shape...

Genetic management of endangered species at the Patuxent Wildlife Research Center Genetic management of endangered species at the Patuxent Wildlife Research Center
Summary: The Patuxent Wildlife Research Center conducts one of the world's largest and best-known research programs for captive propagation of endangered wildlife. In order to be effective and to ensure the long-term survival of species, researchers at Patuxent attempt to manage captive populations according to the principles of population genetics. This includes the use of estimated...

The use of kestrels in toxicology The use of kestrels in toxicology
Various species of kestrels have become important bioindicators of environmental quality and test species for comparative toxicology in captivity. At least 7 species of kestrels have been used to document the presence of environmental contamination primarily organochlorines and metals, in at least 15 countries. Captive kestrels have been used in studies involving a wide variety of...

Selenium accumulation in mammals exposed to contaminated California irrigation drainwater Selenium accumulation in mammals exposed to contaminated California irrigation drainwater
In May 1984, 332 mammals of 10 species were collected at Kesterson Reservoir (San Joaquin Valley, Merced Co., CA), which had received selenium-laden irrigation drainwater, and at the nearby Volta Wildlife Area, which had not. The study concentrated on the California vole (Microtus californicus); 88 were taken at Kesterson, 89 at Volta. Mean selenium concentrations in livers were as much...
