I'm barely an amateur in terms of IDing the birds, but here's what we think we've observed in the first few days:
Robin
Bluebird
Woodpecker
Black and white warbler
A dove of some sort
A black bird (maybe a blackbird)
Oh, and a couple of squirrels. They seem to like the hot pepper stuff. Go figure! But they haven't even tried to climb the feeder. They are eating the feed on the ground. It's interesting; the birds also seem to enjoy the feed on the ground more than in the feeder. If anyone wants to try this for very minimal cost, just buy some feed, and sprinkle it on the ground; no feeder necessary!
Thanks
@Something Fishy for the idea. It is really beautiful to see, and fun and educational for the whole family מנער ועד זקן, טף ונשים!
