In the winter frost

Skógarþröstur – Redwing – Turdus iliacus

As it gets colder the birds frequent the garden and the feeding trays. Redwings, Blackbirds, Starlings and Redpolls are here in the dozens along with several Crossbills. When it gets well below zero, minus 12° C in the picture, the birds puff themselves up to retain body heat, like the Redwing here.
