Bullfinches (dompap) feed on a wide range of natural foods in winter from the seeds of berries like rowan to maple and nettle seeds and shoots and buds of many different trees and bushes. However, this was the first time I’ve recorded them on guelder rose (korsved) berries, Viburnum opulus. They eat the seeds, discarding the flesh. I’ve only seen waxwings (sidensvans) on these berries before.
