This is Woodstock, a just fledged Northern cardinal, baby of Flitter and Maude (in the post above). He is sort of brown and at this stage it is not clear whether he is male or female.
Here he is a few weeks later; his red plumage is starting to come in. Meanwhile, he is still not a good enough flyer to land on the feeder; so, he eats the seeds on the ground.
Here’s Woodstock two weeks later. Now more red and black, he is an almost a full-grown adolescent. At last, he has made it up to the feeder.
Sorry, the photos in this post are all slightly under- or over-exposed. Jamie
