Turns out the main problem with designating the plastic nest box Magic Purveyor of Tasty Seeds is that after awhile it gets half full of seed hulls. Removed it this morning to clean it out, but caused massive Finstipations when I tried to put it back in. Finally removed the annoying little clips that came with the box and hot-glued wire to it. Much easier to put back in! Unfortunately, it took the Finsters about half a day to forgive the intrusion.

Never fear, though, tasty seeds will win out! I've seen three or four of them snacking this evening.
