Breeding Males, But Not Females, Have Elevated Androgen Receptor Expression in the Northern House Wren (Troglodytes Aedon), a Temperate Songbird with Female Song

The study compares androgen receptor and related gene expression in male and female northern house wrens across seasons, finding males have higher expression in song nuclei, suggesting testosterone's greater role in male song.

Seasonal neurogenomic changes provide genetic links between male song and testosterone-mediated neurogenesis in a wild songbird

This study identifies seasonal gene expression changes in a songbird's brain linked to testosterone and neurogenesis during breeding transitions.
