someone after a room upgrade

Lucky for this youngster, it was school holidays and a teenager was roaming around early this morning (we're talking in terms of teenager early).

I think nest 3 is missing a youngster. They are due to fledge about now, so makes sense. The cup appears to have only one or two occupants now. 3 fledged nests, two currently feeding and one incubating/feeding is more than seemed possible a few months ago.
