This was a one day visitor to our yard on its way back to its northern breeding home. We caught this little thing eating cabbage beetles. So if I have anything negative to say about it, it is the fact the bird moved on. We have been dealing with too many of these with our expanded garden.
Editing to add:
After two years of just one day visits, in 2014 they decided to stay around longer. With the cooler temperatures, they didn't eat too many bugs, but ate a lot of millet.
