Evaluating the Use of Autonomous Recording Units to Monitor Yellow Rails, Nelson's Sparrows, and Le Conte's Sparrows
… A standardized protocol for monitoring secretive marsh birds exists (Conway 2009, 2011); however, these species call at night and may be missed during early-morning marsh bird surveys. I tested the effectiveness of autonomous recording units (ARUs) to survey these species by analyzing …

Understanding the spring migration ecology of Sora and Virginia Rail in central Illinois: a study utiilizing automated telemetry
… Rail (Rallus limicola) belong to the family of marshbirds called Rallidae which consists of rails, coots, and gallinules. These secretive marshbirds are difficult to detect due to their cryptic nature in the dense emergent vegetation of wetlands. Detailed information about the spring migratory …

Estimating Forage Production for Waterbirds and Waterbird Response to Habitat Management at Lacreek National Wildlife Refuge, South Dakota
… wintering on the refuge. Population changes of secretive marsh birds were also analyzed to determine if moist-soil management practices were having any impacts on breeding marsh bird numbers. This study focused on habitat associated with breeding American bitterns (Botaurus lentiginosus), soras …

Modeling the spatial and temporal dynamics of coastal marsh birds
Wetland birds are likely to be influenced by habitat at multiple spatial scales, yet few studies have investigated bird responses at both broad and fine scales. Northern Gulf Coast marshes are dynamic ecosystems, and they provide an ideal place to examine habitat across spatial and temporal scales. …
