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. …

The status and distribution of rails and other marsh birds in natural and restored wetlands in northern Indiana
… loss on the populations of rails and other marsh-nesting birds. There can be little doubt, however, that the loss of Indiana wetlands during historic times has caused a dramatic decline in rail populations.Using tape-recorded calls to elicit vocalizations, the status and distribution of five …

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 recorded …

Estimating Forage Production for Waterbirds and Waterbird Response to Habitat Management at Lacreek National Wildlife Refuge, South Dakota
… 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 (Porzana …

Landscape Characteristics Affecting Habitat Use and Productivity of Avifauna on Stock Ponds in Western South Dakota
… landscapes is a sound management strategy for marsh birds. If the amount of tilled cropland continues to increase in fragmented landscapes. it is hypothesized that eventually this portion of western South Dakota will become similar to the prairie pothole region, and, as such, waterfowl …

Wildlife Habitat Evaluation of the Unchannelized Missouri River in South Dakota
… (9 percent), elm-oak (7 percent), cattail marsh (3 percent), sand dune (3 percent), and sand bar (1 percent). All non-developed habitats except sand bar were sampled to obtain vegetative composition and to determine their value to wildlife. The value of each habitat to nine faunal groups of …
