The paper quantifies song complexity in 4,940 bird species and finds a latitudinal gradient linked to ecological and evolutionary factors rather than traditional explanations.

This study examines the relationship between corticosterone levels in feathers and feather growth rate or quality across passerine birds, finding no association but suggesting elevation may influence corticosterone levels.

This study investigates conspecific brood parasitism in barn swallows and finds it rare, challenging previous assumptions and highlighting the need for rigorous genetic validation.

The paper presents complete GRC assemblies from passerine birds, revealing their composition, evolution, and dynamic nature despite their stability in the avian karyotype.

The paper compares plasma steroid hormone levels between Afrotropical and Palearctic passerines, finding lower baseline corticosterone and testosterone in tropical species.

This study shows that recent breeding experience improves egg ejection behavior in barn swallows, suggesting awareness of own egg-laying is key, not a template image.

This study assesses the impact of Colophospermum mopane dominance on biodiversity in South African savannas, finding reduced species richness and community shifts in birds, mammals, and insects.

This study compares human and machine learning accuracy in identifying parasitic eggs using UV-visible photographs, finding machine learning models significantly outperform humans.

The paper identifies a centromeric satellite repeat in songbirds and shows it is absent from the germline-restricted chromosome (GRC), suggesting sequence changes underlie its programmed elimination.

The paper identifies germline-restricted chromosomes (GRCs) in 6,700 passerine species, showing rapid evolution and functional gene retention despite programmed DNA elimination.

This study investigates the mechanisms and timing of programmed DNA elimination in songbirds, identifying key cellular and epigenetic processes involved in the removal of the germline-restricted chromosome from somatic cells.
