Summer plumage

Auðnutittlingur – Redpoll – Carduelis flammea, in July

In summer the Redpolls often become rather rough and darker than in winter and spring. They probably replace old feathers (moult) and gradually take on a new and fresh plumage. To see the difference there is a picture from July 12 above and below another from the end of April.
