DISCRIMINATING OVERWINTERING ORIGIN AND MIGRATORY CONNECTIVITY IN A LONG-DISTANCE MIGRATORY SHOREBIRD STAGING IN THE CANADIAN PRAIRIES
Migratory birds are experiencing widespread global declines. Shorebirds appear to be experiencing some of the most dramatic declining population trends, with the long-distance, Arctic-breeding migrants apparently losing ground the fastest. Challenges arise in monitoring these populations as they …

Migratory connectivity and differential patterns of decline in Barn Swallow (Hirundo rustica) in North America: Potential effects of factors on breeding and wintering grounds
Populations of several Neotropical migratory bird species have experienced declines in the recent decades but long-distance migrant aerial insectivores seem to be declining at greater rates than any other group. The Barn Swallow (Hirundo rustica) is a long-distance migrant and an aerial insectivore …

Understanding the spring migration ecology of Sora and Virginia Rail in central Illinois: a study utiilizing automated telemetry
… wetlands. Detailed information about the spring migratory connectivity and stopover ecology of Sora and Virginia Rail is lacking. Much of the wetland habitat required by these secretive marsh birds has been lost across the Midwest over the last 200 years due to agriculture and urban development. …

Advancements in Isotopic Geolocation Tools for Insect Migration Research
Migratory insects are vital components of global ecosystems and provide important ecosystem services, yet the migration phenomenon is understudied in insects compared to vertebrates. In this thesis, I aim to deepen our understanding of insect migration, using the monarch butterfly Danaus plexippus …

Spring Migration Ecology of American Woodcock (Scolopax minor) in the Central Management Region of the United States
<p>American woodcock (Scolopax minor) is a migratory game bird in population decline since the start of monitoring in 1968. Researchers are interested in gaining knowledge of spring migration ecology to improve migration habitat and mitigate population decline. I captured six woodcock with mist and …
