Dispersion patterns of Holarctic-breeding, migrant landbirds : global paradigms or regional patterns?
This study quantifies the breeding and wintering ranges, habitat occupancy, diet and foraging mode of each migrant taxon on each of the three flyways. It aims to compare how patterns of migration between the temperate and tropical latitudes vary spatially in response to a) the geography of the land …

Predicting extinction risks to landbirds on tropical islands : a Western Indian Ocean model
Includes bibliographical references.

Using banding data to assess the use of 100-meter-wide habitat corridors by breeding landbirds, in an intensively managed pine landscape.
… landscape that would be beneficial to breeding landbirds. To address this question, avian productivity and abundance were monitored using nest searching, point counts, territory mapping, and mist netting. The objectives of my study, based on banding data, were to see how birds were using the …

Migration Plasticity as an Adaptation to Climate Change: The Spatial Distribution and Abundance of a Subset of Neotropical Migrant Landbirds Wintering in the Northeastern United States
… December presence of seven neotropical migrant landbirds near the northern edge of their winter ranges. CBC data and historical weather data from the U.S. Historical Climatology Network (USHCN) were analyzed to confirm the northward shift in average abundance over time among species near the …

Relationship of human intrusion on avian body mass: Do recreationists hinder birds’ abilities to acquire fat during migration?
Many North American landbirds undergo biannual migration, which is energetically costly. Quality stopover sites are crucial to avian survival, as they provide opportunities to quickly replenish fat stores, rest, and avoid predation. One component of habitat quality that is often overlooked is the …

The Effect of Area on Resource Competition among Migrant Birds at a Stopover Site
… habitat and resource requirements of migratory landbirds along migration routes. Habitat fragmentation may exacerbate the costs of migration by reducing food availability and/or increasing competition at crowded stopover sites. I predicted that smaller forest fragments would have higher …

Bayesian hierarchical models for estimating nest survival
… a critical value in avian study to evaluate the landbirds populations. The widely used likelihood-based logistic regression model was evaluated in the first part of the dissertation. In this part, we investigated the importance of nest age in estimating survival rates and measured the model …

Landscape Ecology of Birds on Mount Leconte, Great Smoky Mountains National Park
<p>Landbirds form a significant component of wildlife resources in the Great Smoky Mountains National Park. The present study explored how forest structure and composition of deciduous-coniferous ecotones influenced diversity, richness, and relative abundance of bird species and how bird species …

Migratory Stopover of Songbirds in the Western Lake Erie Basin
… attributes that support high numbers of migrant landbirds during stopover is needed to develop conservation strategies for these species, many of which are in decline. I examined how migrant density during stopover in the Western Lake Erie Basin (WLEB) of Ohio was influenced by local- and …

Assessment of Factors Influencing Migratory Landbird Use of Forested Stopover Sites Along the Delmarva Peninsula During Autumn Migration
… survival of the hundreds of species of migratory landbirds that migrate annually, and thus identifying important stopover sites is a high priority for conserving such taxa. The Delmarva Peninsula; a coastal region of Delaware, Maryland, and Virginia along the mid-Atlantic flyway; consists of …
