Biomarkers of contaminant exposure in common terns and black-crowned night herons in the Great Lakes Biomarkers of contaminant exposure in common terns and black-crowned night herons in the Great Lakes
Morphological and biochemical indexes of contaminant exposure were examined in hatching common terns (Sterna hirundo) and black-crowned night herons (Nycticorax nycticorax) from industrialized and nonindustrialized locations in the Great Lakes. In 1984, naturally incubated, pipping common tern and black-crowned night heron embryos collected from industrialized locations exhibited smaller...

Sampling bird communities in bottomland hardwood forests of the Mississippi Alluvial Valley: Number of points visited versus number of visits to a point Sampling bird communities in bottomland hardwood forests of the Mississippi Alluvial Valley: Number of points visited versus number of visits to a point
Within each of 4 forest stands on Delta Experimental Forest (DEF), 25 points were visited 5 to 7 times from 8 May to 21 May 1991, and 6 times from 30 May to 12 June 1992. During each visit to a point, all birds detected, visuallyor aurally, at any distance were recorded during a 4-minute interval. Using these data, our objectives were to recommend the number of point counts and the...

Species richness and relative abundance of breeding birds in forests of the Mississippi Alluvial Valley Species richness and relative abundance of breeding birds in forests of the Mississippi Alluvial Valley
In 1992, the Vicksburg Field Research Station of the National Wetlands Research Center initiated research on the ecology of migratory birds within forests of the Mississippi Alluvial Valley (MAV). The MAV was historically a nearly contiguous bottomland hardwood forest, however, only remnants remain. These remnants are fragmented and often influenced by drainage projects, silviculture...
