To our surprise, we discovered when we got home Monday night that some birds had decided our larger tomato pot was a perfect place to build a nest! Figuring it wouldn't hurt the tomatoes and not wanting to disturb their hard work (I am amazed at the work these little birds can do!), we left it alone.
Then this morning I found a robin's egg in the nest! Did a little searching on the web and it looks like we'll see at least one baby robin in a couple of weeks!
