Something's Eating Our Rhubarb - Rufus Sided Towhee

I was just out looking at my rhubarb plants, when I heard a rufus-sided towhee say "drink your tea." First time this season. Something is eating our rhubarb leaves. Very annoying. My transplanted rhubarb is still living, though it seems to be collecting snails. I'm going to have to see what to do about that. I need to find some vegetable that will grow well in partial sun. That area under the "fake woods" looks too nice to not do something with. Mild spring day today with complete overcast. But you can still feel the sun through the clouds. We've had a bit of rain overnight and perhaps this morning, and it feels humid. The moisture will be good for growing things.
