Look closely at this bird. Notice anything missing? This is a male American goldfinch in summer/breeding plumage. Bright yellow body, black wings and tail...
Here's a photo of a different male American goldfinch. Notice the prominent black cap? Now look again at the male above. And, when you're ready, scroll down to the third image in this post.
This is the male American goldfinch we call Half-cap. He's been around our farm for more than a year. We're not sure why he has just half a black cap. Was it some genetic abnormality? Is he half female? Was he injured on his head at some point in his life?
Whatever the reason, he seems to be otherwise normal and enjoys all the things goldfinches do—sing, chatter, visit the feeders, fly around the valley in noisy, undulating flocks.
It's always nice to see him. He's another one of our marker birds—birds with a telltale physical feature that makes them easy to spot as individuals. We've had Mr. Troyer, the male eastern bluebird with a droopy wing from a sharp-shinned hawk attack; Snowflake the leucistic dark-eyed junco, and a few others.
I'm hoping Half-cap enjoys a long, fruitful life here on our farm.
