Disturbance during development may have lasting effects on the growth rates and stress physiology of birds. Although repeated handling by researchers is often necessary, the possible effects of such handling on the development of semi-altricial [...]

Five subspecies of Dunlins (Calidris alpina) that breed in Beringia are potentially sympatric during the non-breeding season. Studying their ecology during this period requires techniques to distinguish individuals by subspecies. Our objectives [...]

Heat-shock proteins (HSP) are molecular chaperones that play key roles in the maintenance of cellular homeostasis under variable environmental conditions. Although HSP are frequently used in studies of wild vertebrates as indicators of stress, n[...]

Fledging is a critical event in the avian breeding cycle, but remains unstudied in almost all species. As a result, little is known about factors that cause nestlings to leave nests. We documented fledging behavior in a box-nesting population of[...]

The ability of sexually mature non-territorial floaters to sire offspring affects the success of floating as a breeding strategy. Red-winged Blackbirds (Agelaius phoeniceus) have second-year (SY) and after-second-year (ASY) floater males, and ge[...]

Use of soft-metal (aluminum alloy) bands on gulls (Laridae) is known to result in high rates of band loss and, as a result, hard-metal (monel, incoloy, or stainless steel) bands are superior for most studies. However, the U.S. Bird Banding Labor[...]

Prescribed burning maintains marsh habitat, but its impact on breeding King Rails (Rallus elegans) is poorly understood. This practice may serve as a means to enhance populations of a species whose numbers are declining in the southeastern Unite[...]

Conditions in wintering areas can have persistent effects throughout the year for bird populations. Most studies, however, are conducted during the breeding season and the non-breeding ecology of many species remains poorly understood. We assess[...]

Despite concerns about their population status, information about the habitat preferences, population size, and vital statistics of Wilson's Plovers (Charadrius wilsonia) is currently lacking. We compared habitat characteristics of nest sites an[...]
