The paper investigates whether shared genetic variation drives repeated evolution of migratory behavior in songbirds and finds no evidence of selection on candidate genes for this trait.

The paper shows how Barn Swallows overcame inbreeding challenges by expanding rapidly through behavioral flexibility and genetic variation during cross-hemisphere colonization.

The paper uses historical DNA to show that a small population's genetic load was not purged after a bottleneck, despite demographic recovery.

The paper uses whole-genome sequencing of Myioborus warblers to study evolutionary relationships and plumage genetics, finding patterns of colonization, hybridization, and genomic differentiation.

The paper tracks myrtle warbler migration using geolocators and isotopes, finding most birds migrate to the southeastern U.S., not the Pacific Coast as previously hypothesized.

The paper develops an amplicon sequencing method to genotype plumage-associated loci in Vermivora warblers and provides data and scripts for replication.
