Identification of potential harvest units in the United States of the American woodcock
Potential harvest units were examined in the United States for American woodcock (Philohela minor) based on the distribution of both direct and indirect recoveries of preseason bandings. Unweighted and weighted recoveries were used to definefour sets of units with a minimal interchange of birds. With a configuration that conforms to the existing boundary between the Atlantic and Mississippi wate

Impact of estuarine pollution on birds
Pollution of estuaries affects bird populations indirectly through changes in habitat and food supply. The multi-factor pollution of Chesapeake Bay has resulted in diminution of submerged aquatic plants and consequent change in food habits of the canvasback duck. Although dredge-spoil operations can improve wildlife habitat, they often result in its demise. Pollution of estuaries also affects b

Quantitative analysis of American woodcock nest and brood habitat
Sixteen nest and 19 brood sites of American woodcock (Philohela minoI) were examined in northern lower Michigan between 15 April and 15 June 1974 to determine habitat structure associated with these sites. Woodcock hens utilized young, second-growth forest stands which were similar in species composition for both nesting and brood rearing. A multi-varIate discriminant function analysis revealed a
