Although the Redpolls frequent our feeding trays, they are also diligent in nibbling on seeds from the Sitka Alder and Green Alder. Redpolls eat Birch seeds and all kinds of flower seeds, and insects in the summer time. However, after a cold and wet summer the availability of Birch seeds is scarce.

Recently flocks of Redpolls have been seen feeding on seeds in Alder trees in the South of Iceland.
