I just observed the bird hanging onto my thistle sock and attacking it in much the same way it would a suet feeder.  I had long blamed House finches for this destructive activity although i had never caught them in the act.  It is also a reminder to me that i need to get my actual suet feeders out ASAP and while i'm at it will broom off the ground under the feeders for the sparrows, et al.
