Blue-Winged Warblers (Vermivora Pinus) Versus Golden-Winged Warblers (V. Chrysoptera)

The future of Blue-winged and Golden-winged Warblers in Connecticut

Conservation Practices Benefit Golden-winged Warblers in Appalachia

The golden-winged warbler (Vermivora chrysoptera) is a neotropical migrant songbird that winters in portions of Central and South America and breeds in the northern Great Lakes regions of the United States and Canada, and at higher elevations of the central and southern Appalachian Mountains (Confer et al. 2011). The species is experiencing steep population declines throughout its Appalachian M...

Evaluating outcomes of management targeting the recovery of a migratory songbird of conservation concern

Background Assessing outcomes of habitat management is critical for informing and adapting conservation plans. From 2013-2019, a multi-stage management initiative, led by the American Bird Conservancy (ABC), aims to create >25,000 ha of shrubland and early-successional vegetation to benefit Golden-winged Warblers (Vermivora chrysoptera) in managed forested landscapes of the western Great Lakes ...

Seasonal and population variation in male testosterone levels in breeding orange-crowned warblers (Vermivora celata).

Comparative hormone studies can reveal how physiology underlies life history variation. Here, we examined seasonal variation in plasma testosterone concentration between populations of male orange-crowned warblers (Vermivora celata) breeding in Fairbanks, Alaska (V. c. celata) and on Santa Catalina Island, California (V. c. sordida). These populations face different ecological constraints and e...

Plumage Genes and Little Else Distinguish the Genomes of Hybridizing Warblers

When related taxa hybridize extensively, their genomes may become increasingly homogenized over time. This mixing via hybridization creates conservation challenges when it reduces genetic or phenotypic diversity and when it endangers previously distinct species via genetic swamping [1]. However, hybridization also facilitates admixture mapping of traits that distinguish each species and the ass...
