Seventy year old eyes suck.........
I found it.
I must be missing something, I look and look and all I see is a winter-range Hermit Thrush, doing what hermit thrushes usually do. Fuzzy pic tho and I don’t see the distinctive russet tail, but hermit thrushes are found all across North America and have several subspecies which vary somewhat in appearance. Beautiful song tho, especially in the Eastern forms.
