Junco hyemalis right? I have a whole flock of those that visit daily and refuse to leave the bird feeder during snowstorms. Well, below the bird feeder, they tend to eat what I and the Chickadees drop. However they do seem to be taking stuff out of my feeder this year, maybe because the snow is deeper than usual. They are smarter than a lot of other species in some ways, for example they can remember where I usually leave seed for them and they are willing to dig for seed in the snow if it is not too deep. They are even willing to hop along until they reach the tunnels I dig for them to get to the sheltered seed scattering places.
