That is interesting, you must have a southern / south-eastern location.
I'm sitting at the base of a 12,000 ft. mountain here in Utah, and we get the migrations of the birds that live in the mountains out in the fall and back in the spring. Sometimes they fly up a week or two early, when there are storms up there still, and the valley is thick with cedar waxwings. We have a few hooded orioles for color, some canaries which have acclimated to the wild, and some pale orange birds more civilized than sparrows. Being on a migratory path for arctic birds going north and south, Utah has a fair number of bird-watching clubs.
I like the heated bird bath idea. I may add that to the hawk feeder.

This link shows exactly what we saw tonight when we went down to the lake at sunset (The view is facing east) and we are located right square in front of the center of that mountain Timpanogos.
Woa!
Wow! Gorgeous!
