Painted Buntings (Passerina ciris) have been declining in the southeastern United States since the 1970s. A recent demographic assessment highlighted the importance of estimating demographic parameters, which have received little attention to date. T

— Understanding natal dispersal and rates of philopatry can help provide minimum estimates of juvenile survival, a vital demographic parameter for which little information is available. However, despite the large number of hatch-year migratory bird

Despite advances in tracking technologies, migration strategies remain poorly studied for many small-bodied passerines. Understanding variation within a migration strategy is important as variation impacts a population’s resilience to environmental

We studied the nesting ecology of Swainson's Warblers (Limnothylpis swainsonii) in Britton's Neck, South Carolina, USA and found 144 nests of which 78 were active. Nest initiations followed a bimodal distribution. Clutches averaged (± SE) 3.19 ± 0.

Swainson's Warbler (Limnothlypis swainsonii) breeds in bottomland hardwood forests across the southeastern United States, where it is believed to be one of the rarest breeding songbirds. Although information on its nest-site habitat is considerable,

We examined factors affecting the nesting success of a migratory songbird, the Acadian flycatcher (Empidonax virescens), in loblolly pine plantations in the coastal plain of South Carolina, USA. From 1997–2000, we located and monitored 163 Acadian

Little is known about factors that structure biodiversity on landscape scales, yet current land management protocols, such as forest certification programs, place an increasing emphasis on managing for sustainable biodiversity at landscape scales. We

Forest structural features at the stand scale (e.g., snags, stem density, species composition) and habitat attributes at larger spatial scales (e.g., landscape pattern, road density) can influence biological diversity and have been proposed as indica

Migratory species can comprise 80-90% of the breeding birds in eastern deciduous forest habitats (Whitcomb 1977, Kilgo 1996) and 45% to 65% of the birds in southeastern bottomland hardwood forests (Dickson et al. 1993, 1995; Pashley and Barrow 1993).

Selection of scale is critical when investigating ecological processes on landscapes because different patterns emerge in spatial data at different scales. Landscape studies commonly identify a single scale, or spatial extent of data, for assessing b
