I had a HUGE (Hyuge) murder of crows in the back yard yesterday. Reminded me of that old Black and White movie, “The Birds”. There had to be a couple of hundred or more.
SE Tennessee here. I haven’t noticed any robins yet, but my usual gang are hanging around the feeder every day - Cardinals, woodpeckers, mourning doves, Nuthatches, and mockingbirds. It was a little chilly this morning, but it’s sunny and bright out there.
For interesting winter bird watching get yer self a Bird Bath Heater.
Mine sits in a plastic, very large flower pot tray on a stand and is under the shed overhang. Goes on and of at specific temp and shuts of if the level goes too low.
Had it for 15 plus years and its fun to see the Jays and other winter hangers on in there when its in the single digits.
