The current status of woodcock and woodcock surveys in the United States
A comparison of American woodcock (Philohela minor) wing collection survey data for 1975-76 and 1976-77 showed that there was little change in the indices to breeding success and hunter success between years in the Atlantic and Central regions. The 1977 breeding population index was up 15.2 percent from 1976 in the Central region and static in the Atlantic region. There is a long-term decline in t

Research, management, and status of the osprey in North America
Osprey populations were studied throughout North America during the last decade as a result of dramatic declines reported along the North Atlantic Coast in the1950s and early 1960s. Researchers used banding, localized studies, aerial surveys, and pesticide analyses to identify factors influencing regional populations. Declining populations showed extremely poor production, contamination by envir

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

Woodcock utilization of commercial timberlands in the northeast
This paper reports the results of studies in Maine (1975-77) and New Brunswick (1974) on the utilization of commercial timber areas by woodcock (Philohela minor). Openings created by logging operations were utilized for singing grounds and nocturnal roosting habitat. Singing male densities of 3.4 birds/1oo ha on were found on New Brunswick elearcuts, 0.24 birds/IOO ha on northern Maine elearcuts

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
