Goldfinch with abnormal plumage
This Goldfinch has been visiting the garden over several weeks. In place of the black heading markings is an area of white, meaning that this bird is suffering from some form of plumage abnormality. The BTO is running an Abnormal Plumage Survey and wants to hear from you if you have seen a bird with unusual plumage, perhaps a Blackbird with some white feathering. You can access the BTO pages on abnormal plumage here.
