Embryotoxicity, teratogenicity, and aryl hydrocarbon hydroxylase activity in Forster's terns on Green Bay, Lake Michigan Embryotoxicity, teratogenicity, and aryl hydrocarbon hydroxylase activity in Forster's terns on Green Bay, Lake Michigan
Known reproductive problems, including congenital malformations and poor hatching success, exist for the state endangered Forster's tern (Sterna forsteri) in Green Bay, Wisconsin. Twenty Forster's tern eggs were collected from separate nests at (i) a natural colony with documented reproductive problems, situated at Green Bay, Lake Michigan, and (ii) an inland colony at Lake Poygan...

A quick-catch corral trap for wintering canvasbacks A quick-catch corral trap for wintering canvasbacks
We designed a bait trap for wintering Canvasbacks (Aythya valisineria) that has proven more effective than conventional funnel or slot entrance traps for diving ducks. The unique feature of this trap is the corral entrance that presents unimpaired access to the bait and thus ease of entrance to the trap. Catches of 50-75 ducks have been made in a matter of minutes at prebaited sites.

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...
