Great feeder until, as with Judith, a squirrel decided to put the bite on the exposed, top plastic parts of the seed tube. Totally destroyed. I'm now in the pleasant misery of trying to replace the tube. If you buy this otherwise great Goldfinch feeder, shape a 1/4 inch metal mesh cover over the vulnerable top and bend the end wires to keep it in place. Otherwise, this thing is too expensive to put out for tree rat marauders.
