Last week I put up a bird feeder on my balcony. As far as I can tell, the birds have not found it. However, I do see lots of different birds from my balcony. I know most of them but every once in awhile I see one that I don’t know. For example, the one below showed up today and I don’t know what kind of bird it is. Any help would be greatly appreciated.

Update! I have found out that it’s a female Downy Woodpecker!
