Eh Tu, Towhee?

Is there something in that feeder I need to know about?  Just two days ago I marveled at the use of our Mega Sunflower Tube by an unexpected Red Bellied Woodpecker.  And now I find...Eastern Towhees!  Another species that I do not recall ever seeing use a tube feeder, or practically any other feeder.  These birds scratch for eatings on the ground and don't like to get into exposed situations.  Yet there was photo after photo with that towhee working out seeds.  Just a reminder that even backyard birds can be full of surprises!
