This is not a great picture for ID purposes, but it's what you get shooting through a grimy window. I enlarged and cropped the original, then increased the clarity; otherwise, the birds would have been essentially invisible. The bird on the left, facing the camera, is of interest as I've never seen one at these feeders before. I'm thinking Song Sparrow but would appreciate other opinions. The one on the right, if I recall, was a Yellow-rumped Warbler, a regular at my feeders. The other possibility would be one of the Chippies that often hang out there, but they aren't streaky.
