The Black Rail (Laterallus jamaicensis) is the most secretive of the secretive marsh birds and one of the least understood bird species in North America. The Eastern Black Rail (L. j. jamaicensis) is listed as endangered in five states along the Atlantic Coast and is under review for federal listing. Historical population size was likely in the tens of thousands but is now believed to be in the hundreds or low thousands (Watts 2016). Within the United States, Eastern Black Rails breed within three general geographic areas within the United States - the Atlantic Coast, the Gulf Coast and the Midwest-Great Plains. The Atlantic Coast has generally been considered to support the largest breeding population throughout...
Much of the focus of Red Knot research and conservation over the past twenty years has largely focused on just a few sites along the Atlantic flyway, primarily in the mid-Atlantic region. The major cause of the Red Knot population decline in the 1990’s through 2003 was mostly attributed to declining horseshoe crab numbers in Delaware Bay due to their overharvest for the commercial bait industry. Substantial focus has been placed on improving horseshoe crab populations through better horseshoe crab management in the Delaware Bay region and on improving horseshoe crab and shorebird habitat in Delaware Bay. This work has likely halted the decline in the numbers of Red Knots passing through Delaware Bay: populations...
Migratory birds are responding to changes in climate in complex and sometimes unpredictable ways. The timing of breeding and migration typically coincide with the periods of peak food availability; however, these peaks are shifting as temperatures and precipitation patterns change, resulting in a mismatch in the timing of key events. The degree to which this mismatch is impacting migratory birds varies among species and regions, creating a major source of uncertainty for managers. The goal of this project is to develop tools to support migratory bird management decision-making in the face of uncertain future climate and land use conditions. In order to identify and implement the most effective management strategies,...
