One of the Black-capped Chickadees takes a sunflower seed from a handful I had scattered on the snow-covered wood pile. If you click on the photo to enlarge it, you will be able to see the chickadee's tongue.
The little Red-breasted Nuthatch is here most days and is a delight to watch. *He is certainly outnumbered by the chickadees, but that does not bother the nuthatch at all. If a chickadee is in his space, he scolds with a short "pfft". He might even take an aggressive hop towards the chickadee causing the poor reluctant bird to fly off to a nearby perch and wait until the nuthatch has left.
*I'm not positive that this is a male Red-breasted Nuthatch.
