American Redstart

The five genetically distinct populations of American Redstart (Setophaga ruticilla) across the breeding range (left map). PCANGSD-ADMIX was used to estimate probability of membership to distinct genetic clusters. Individuals sampled on the wintering grounds (right map) were then assigned back to a genetic cluster, allowing us to better understand the migratory connectivity of American Redstart populations. Wintering birds were assigned to genetic clusters using WGSassign. Genetic clusters are visualized as transparency levels of different colors overlaid upon a base map from Natural Earth (naturalearthdata.com) and clipped to the species breeding range using an eBird shapefile.

We worked in collaboration with Pete Marra of the Smithsonian Institute, Mike Webster of Cornell University, Thomas Sherry of Tulane University, Nick Bayly of SELVA, Keith Hobson of Environment and Climate Change Canada, and Lisle Gibbs of Ohio State University to build a genoscape for the American Redstart (Setophaga ruticilla).

See below for details of samples used.
