Stopover duration and habitat use of spring-migrating dabbling ducks in the Wabash River Valley, USA
… period of the waterfowl annual cycle. Stopover sites along migration routes contain habitats and resources required by waterfowl to rest and refuel before continuing north to the breeding grounds. The Wabash River Valley (WRV) in southeastern Illinois provides habitat for over 500,000 …

Improving the Use of Migration Counts for Wildlife Population Monitoring
… vs. non-daily sampling) and a temporal change in stopover duration (and thus detection probability) influenced our ability to estimate the known trend. I also tested whether analyzing data as hourly, daily or annual counts, or accounting for random error using analytical techniques, could improve …

Ecology of fall-migrating ducks in central Illinois: a radar perspective
… ducks as they emigrated from this important stopover area. With this technique, I quantified duck emigrations during 7 falls (1996, 1997, 2003, and 2005-2008). I used WSR-derived estimates of annual turnover in combination with aerial inventory estimates of duck use to estimate the average …

Stopover behavior and refueling physiology in relation to migration distance in Wilson's Warblers (Wilsonia Pusilla)
… migration distance within a species affects stopover behavior and refueling rate. Wilson’s Warbler is a leapfrog migrant passerine that winters in Central America and breeds throughout North America. Birds were captured in the spring and fall of 2006 during passage through a desert stopover …

Understanding the spring migration ecology of Sora and Virginia Rail in central Illinois: a study utiilizing automated telemetry
… 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. Stopover sites are critical …

Effects of Hurricane Disturbance on the Stopover Ecology of Intercontinental Landbird Migrants in Coastal Louisiana
… of weather events on migratory birds during stopover, and essentially none on how hurricanes affect their stopover biology during spring passage. About two thirds of eastern North American forest breeding bird species migrate twice annually between temperate breeding areas and subtropical and …

Piping Plover (Charadrius melodus) demography, behavior, and movement on the Outer Banks of North Carolina
… models on resighting and count data to estimate stopover superpopulation and stopover duration of migrating birds based on their breeding region of origin. Annual survival of adults from North Carolina (x ̅ = 0.69, SE = 0.07) was not different from another population on Fire Island, New York (x ̅ …
