Earthworm populations as related to woodcock habitat usage in Central Maine Earthworm populations as related to woodcock habitat usage in Central Maine
Lumbricid earthworms were sampled 'on two central Maine study areas between late April and early September, 1974, to relate earthworm abundance to use of feeding covers by American woodcock(Philoheli minor). On sampling days, occurring at 2 to 3 week intervals, a formalin solution was applied to thirty O.25m areas in heavjly, commonly, and rarely used woodcock covers (5 samples/type of

Experimental woodcock management at the Moosehorn National Wildlife Refuge Experimental woodcock management at the Moosehorn National Wildlife Refuge
The purpose of this study is to develop woodcock(Philohela minor) management techniques that can be easily used by the small landowner or incorporated with other land management operations such as commercial timber harvesting. The Moosehorn National Wildlife Refuge contains areas which are characteristic of the abandoned farms now being purchased for recreation or retirement as well as...

Identification of potential harvest units in the United States of the American woodcock 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...

Impact of estuarine pollution on birds 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...
