Hi,
There is bird come with some goldfinches. But it doesn’t has a red face, and its pattern of the head looks different with others (picture might not super clear) . The rest body part is same with other goldfinch.

Our herring gulls are red listed birds. Think about that the next time you hear some flaming idiot calling for a cull of them.
