The Tomato Thiefs?

A few weeks ago I was out in my yard piddling around. My house has tons of woods around it with all kinds of animals. I noticed four woodpeckers and decided to sit and watch for a bit. These were the bigest woodpeckers I have ever seen and what seem so weird was that they were acting like young birds and not older ones. They stayed in pairs of two and were acting like they were learning to peck on the trees. I got a picture of these two. It was really hard to show in the picture, but they are just absolutely huge. Never in my life have I seen them this big. Wonder if there's something in my woods that they're feeding on that made them so big ... or are they the ones who have been stealing my ripe tomoatos? Time to do some investigative work. Stayed tuned for the update on the tomato thiefs.
