My family is very proud of a family of Blue Birds they got to nest in this very special bird box in the back yard. So proud, they asked me if I wanted to look in the box to see the eggs. "Sure", I said. Billy goes and pops the top off of this bird box, I look in. "Billy, there are no eggs. " "WHAT!" *eyes pop out of head in a very dramatic way.
Apparently some other birds, (Wrens) like to wreck Blue Bird nests and then use them for themselves. We knew the Wrens did it. All the Blue Bird eggs were in the grass broken and there were some thick twigs in the bird box.
Billy pulled the old nest out, for the birds to start a new one.
