Yes John. It would be an interesting project. I've been recording the YTBCs 
flying over Uriarra Village for a few months now. If someone wants to do a more 
comprehensive study they are welcome to my notes. Yesterday there was a large 
flock of 60+ which arrived at the woodland adjacent to the western horse 
paddock at 5.15pm. There seemed to be a lot of quarrelling over roosting spots 
and a group of 10 birds had to make do with an isolated tree in the paddock. 
It's the first time I've seen them roost in the open.
