At the end of last week, I saw a male goldfinch. I was amazed and thrilled to see that he is starting to turn yellow. Their winter plumage is a very dull olivey green-yellow. The guy I saw had a distinct yellow tinge to his head. You would've thought I was daft to see how happy that made me! In spite of the wintry look of things these days, spring really is coming.
Here is a female in summer plumage. They are much duller than the males, so that they won't be noticed when on the nest.
