I've had a couple hanging around for a while now. One of them nearly knocked me over the other day when I took the feeder down to refill it. Pushy little bugger.
I only have a couple right now. I believe you'll find that any in the neighborhood right now are sitting on eggs. You'll wake up one morning and they'll be all over. Don't stop putting your feeder out.
I think the storm we had a couple or 3 weeks ago killed some of mine. I had seen at least 8 at a time and thats all I could count. Ever since the very strong wind I have just seen 3 at a time.
