At least I'm pretty sure it is a Tufted Titmouse. The ap on my phone couldn't get more precise than "Titmice".
The birds (this morning) are stopping by the feeder just long enough to grab a seed then leave. Probably because of the squrrels that are hanging around.
I should probably clean up the feeder, it's actually brass, but with a decade or so of weathering. Incuding some hail damage...
Thanks all!
