Hello to all. My name is Bob and I live in Northern Wisconsin. I have had a male Cardinal coming to my feeder and birdbath for a couple of weeks now that has no feathers on his head. I have read that this is from some sort of parasite. The rest of his feathers look pretty bad too. he keeps ruffling them and he keeps rubbing his beak on the edge of our deck. It's pretty cold, damp and windy today and he just looks so miserable. Is there anything I can do for him?
