The annual course of plasma testosterone (T) and song activity during the day was examined in free-living male great tits (Parus major) in a single year and in a single population. We provide the first study in this species investigating plasma T during the breeding season among and within breeding stages. As expected for a temperate-zone monogamous species, plasma T levels showed a pronounced peak in March at the start of the breeding season and fast decreasing levels thereafter to moderate… CONTINUE READING
