Confirmed the black cap, gray/blue overall colour, black on upperside of tail and red underneath with the black eye. Size is right. Has been feeding from my platform feeder and suet wreath since Dec 30th. Feeds, then flies low to the ground into the lower branches of the cedar hedge or cedar trees. Very exciting to see a gray catbird, I understand it should be considerably farther south in winter. One has been nesting here for the last 2 summers. I had a chance to observe it at length and can confirm 100% it is a gray catbird. Going to put up my trail camera and see if I can capture some video /pictures.
