Changes in Avian Capture Rate and Migration Phenology Across 37 Years at a Coastal Barrier Island in Georgia
… Banding Station in Georgia. Capture rates of Neotropical migrants on Jekyll have declined 50-90% in many common species, and the mean ordinal passage date of Gray Catbird and Western Palm Warbler have shifted 8 days later. Landcover analysis of the island yielded non-significant results; …

Forest songbird abundance and viability at multiple scales on the Monongahela National Forest, West Virginia
… = 0.08). Abundance of forest-interior species, Neotropical migrants, and nine key indicator species were greatest in the mixed mesophytic (p < 0.05). Bird abundance and species richness differences at the transect scale were significant (p < 0.001) and were related to differences in stand height …

Relationship of human intrusion on avian body mass: Do recreationists hinder birds’ abilities to acquire fat during migration?
… between migratory guilds indicate long-distance migrants require areas of low intrusion to sufficiently acquire fat stores. In contrast, resident species are able to replenish body mass despite human intrusion. Since Neotropical migrants show increased sensitivity to human presence, conservation …

Avian Community Structure Associated With Woodland Habitats in Fragmented and Unfragmented Lanscapes in Western South Dakota
… in woodland habitats. Woodland obligate and Neotropical migrant species richness values were higher in nonfragmented landscapes whereas more species of edge and generalists were observed in fragmented landscapes. Greater vegetative diversity of natural woodlands attracted significantly more …
