We retrospectively evaluated 20 y of using predator-deterrent fences to mitigate unusually high nest predation for the critically endangered Attwater's prairie-chicken Tympanuchus cupido attwateri at the Attwater Prairie Chicken National Wildlife Ref

We determined reference levels of minerals, fatty acids, and fat-soluble micronutrients in eggs from wild Attwater's Tympanuchus cupido attwateri and two (Minnesota, Nebraska) greater prairie-chicken T. c. pinnatus populations for comparison with egg

The invasive red imported fire ant (Solenopsis invicta) has negatively affected a host of taxonomic groups throughout its acquired North American range. Many studies have hypothesized indirect trophic impacts, but few documented those impacts. We eva

Twenty adult male American Bitterns (Botaurus lentiginosus) were marked on summer range in central North America with satellite tracking Platform Transmitter Terminals (PTTs) to document migration routes and wintering range. Nineteen complete fall mi

The number of greater prairie-chickens in Wisconsin has decreased by 91% since 1932. The current population of approximately 1500 birds exists primarily in four isolated management areas. In previous studies of the Wisconsin populations we documented

Over the last century, populations of the Greater Prairie Chicken ( Tympanuchus cupido ) have de- clined or gone extinct throughout midwestern North America. In Wisconsin the population declined by 50% from 1951 to 1961 and has remained at low (1500

Capture techniques were developed to study the American Bittern (Botaurus lentiginosus). Mirror traps, mist nets, landing nets, night capture, funnel traps and net gun techniques were evaluated. Mirror traps and mist nets were used with a tape record

Reticuloendotheliosis (RE) is a viral disease documented from poultry, which has been found to cause mortality in captive Attwater's (Tympanuchus cupido attwateri) and Greater (T. c. pinnatus) prairie-chickens. We surveyed blood samples from 354 Grea

Most life history traits of the American Bittern (Botaurus lentiginosus) have not been studied and are poorly understood. The ability of the American Bittern to renest has not been confirmed previously. A second nesting attempt by an American Bittern
