|Comment||The colouration is certainly right to the extent I almost mentioned this when I posed my question. Only the size gave me pause - the birds appeared much more Cardinal sized to me (seen through 8x40 binoculars). I am quite familiar with the American Goldfinch too as we had a Goldfinch niger-seed feeder at our other house. Interesting how Chickadees at first have difficulty getting at the niger-seeds - but quickly learn the upside-down technique from the American Goldfinches. Thanks Roger.|
