Or birdhouse builders? I started doing this early this year and had several bird boxes made up for a few different species of birds. Made up two for Eastern Bluebirds, 2 for Carolina Wrens, 1 for Chickadees or Titmice, and another for either Screech Owls or Wood Ducks (Depends on how high you put it)... Here's a pic of one of my Bluebird houses. It's made of E.Red Cedar. The tenants' kids. The kids not long after hatching. Not as cute as a baby chicken. Here they are about a week later. And once again, right before they were able to fly. Yeah the poo is nasty... These birds came along in Spring and they survived a few pretty harsh storms. Up until I took the last pic, I thought there were only 5 in the nest, but if you look close enough in the last pic you can see 6. Before anyone asks about me opening up the house, I made it so that it hinges on the front piece. Yes you can take a look at the birds when they're that young. It just makes the parents a little nervous and I had Ma and Pa Bluebird dive-bombing me while I was taking pics of their babies. I was really hoping to attract some Purple Martins here, but from what I've been reading it may be a big pain to do that.
