Plasma antioxidant capacity and oxidative damage in relation to male plumage ornamental traits in a montane Iberian Pied Flycatcher Ficedula hypoleuca population.

The article presents a study on oxidative damage and plasma antioxidant capacity in relation to male plumage ornamental traits in a population of montane Iberian Pied Flycatcher Ficedula hypoleuca. The researchers performed the study in a montane deciduous oak forest at 1,200 meters elevation near Valsaín in central Spain. They also punctured a brachial vein at capture and collected blood in heparinized capillary tubes, which were stored in locked eppendorf tubes in an icebox until returning to the laboratory on the same day.
