Rocky in the back bedroom

This morning, we were eating breakfast in the kitchen. Rocky had been playing in the hallway when suddenly we realized that we hadn't heard him making any noise for a few minutes. That is never a good sign.

We suspected he was in a back bedroom when we noticed that a macaw-sized opening existed:Lately, he's been going in the back bedroom and then climbing on the clothes drying rack we have for out running clothes that can't go in the dryer:
This is so strange! Why would he prefer to be in the back bedroom, all alone, than with his flock? What is so compelling about the clothes dryer? The rack can't possibly be a comfortable perch for him -- look at how skinny it is!

After taking this picture, I left him alone and he came out to find us about 5 minutes later.
