Oh! Another thing that happened this week is that the baby bluebirds seem to be leaving the nest. The other day we watched the mom and dad bluebird doing some crazy stuff around the bluebird box where the male would sit on top of the box and do some weird one-winged wing flapping, and the mom would go in and out of the box. At one point the mom went in and two birds flew out!
My mom told me to tell the bluebird babies that they were too little to leave the nest yet and they should stay a bit longer, but I think their mom said "Thats it!! Out! Get out!!" I don't think they're all out for good yet as the box seems to jiggle around a lot still, suggesting there are still bluebird babies hanging out inside. But I think an empty box is coming pretty soon, and perhaps a new clutch of eggs?
