I took lots of photos hoping to be able to determine whether he was finding bugs under the deer feed, or eating the feed itself. Originally, the feed was moldy and nothing went near it, but after being exposed to rain and sun for months, it seems pretty well sanitized.
I could never detect any insects in his beak, so I'm leaning toward thinking he's eating the feed.
This is the only photo that seems to show something in the beak. I couldn't get as close as I would have liked because that sent him scurrying for cover. I guess those deer pellets are a good source of protein. Just to cover all bases, though, I ordered a bunch of live meal-worms online.
Meanwhile, a Green-tailed Towhee is checking out the grapes. It never did eat one though.
Now the days start to get longer. That always cheers me up.
