I don't know about "old bird house" as I don't know (or can't remember) where that was. to the side of the bird keeper kitchen there's a door that leads to the corridor that goes behind the Islands in Danger aviaries (rollers, azure wings, pied starlings etc). There are a couple of off-show areas on this side of the corridor. I believe these frogmouths will be going into the main owl area when some of the other owls move out.
