My red-bellied has shown up to the balcony suet feeders the last 3 days in a row. He’s easy to startle away, but he eventually returns.

I am so envious of your huge list! Do you document them on eBird? They really like it if you do. (It’s still cornell bird labs, but designed to count known species sighted. It doesn’t do identification. I sometimes start a checklist on ebird, switch over to Merlin and run the sound identification, then go back to ebird to log the “heard. but not seen.”
