Song divergence and a gleaming white iris reveal four species in a widespread Neotropical understory bird (Clibanornis rubiginosus, Furnariidae)

The paper uses song analysis to identify four species within the Ruddy Foliage-gleaner complex, revealing paraphyly and taxonomic splits.

Diversification and divergence in Myioborus warblers: insights into evolutionary relationships and plumage genetics

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

History of divergence and gene flow shaping geographic variation in Andean warblers (Myioborus)

The paper examines genetic and phenotypic variation in Andean warblers, finding geographic and plumage-related genetic structure and a hybrid zone with asymmetric introgression.

Distribution, ecology, and natural history of the recently rediscovered and critically endangered Santa Marta Sabrewing

The paper documents the rediscovery of the critically endangered Santa Marta Sabrewing, describes its ecology and natural history, and suggests it remains critically endangered.

Phenotypic variation and weak behavioral isolation in a putative hybrid zone between Andean Atlapetes brushfinches (Passerellidae)

The paper examines phenotypic variation and behavioral isolation in a hybrid zone between two Andean brushfinches, finding gradual phenotypic transitions and weak prezygotic reproductive barriers.

Shallow evolutionary divergence between two Andean hummingbirds: Speciation with gene flow?

This study examines speciation with gene flow in two Andean hummingbirds, finding low genetic differentiation and no MC1R link to coloration divergence.
