I have noticed this strange behaviour for the past month. I have had this Robin coming under my sunflower feeder and eating fallen seeds. At first, I figured that it was eating insects that were there until tonight. Tonight I saw it up close on my deck eating Black Oil and Stripped Sunflowerseeds. This is really strange. I also saw the robin eating suet 2 weeks ago. I can tell that it is the same bird because of the large puffed up fur on its head.
