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.

The paper identifies a repeat-rich genomic region, MARB, associated with bird migration using long-read assemblies and cytogenetic techniques, revealing it spans a large chromosome and contains many olfactory receptor genes.

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 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.
