We examined the relationship between offspring sex and paternity over six breeding seasons in an Illinois population of the house wren (Troglodytes aedon), a cavity-nesting songbird. Out of the 2345 nestlings that had both sex and paternity assigned, 350 (15%) were sired by extra-pair males....

Indeed, house wren (Troglodytes aedon) females were most likely to produce extra-pair offspring when paired with old males35. Although we did not compare attractiveness between yearling males and old males (more than one year old), one signal indicating male maturation is feather brightness and ...

Evidence supporting these relationships exists but is sometimes mixed or weak. Here we provide...
