I still had well over 100 redpolls daily until today - now maybe down to 50. I too have one little chunky guy - I've named him/her "Pokey" - who's been here all winter and is definitely not quite right. Doesn't take up with the other birds, sits out feeding like a sitting duck when everyone's vacated (i.e. probably a hawk around). I am definitely worried for it, but seems like a resilient little guy and sort of assuming he's a resident now.
