hi,
with regard to the caged bird/vagrant debate, my mum and I were lucky enough to 
be with Joy at the first sighting of the Rosy Starling on the morning of Friday 
3rd 
September.  The bird flew extremely well, towards the end of the sighting it 
flew 
very swiftly and extremely high in a wide arc away to the edge of the plain.  
We 
have seen several aviary escapees in our day, and they have always been poor 
fliers.  The bird also seemed to be in extremely good condition.  There was 
certainly 
no evidence of frayed wing or tail tips.  
It also seemed to be slimmer and lighter in build than birds depicted in the 
few field 
guides we have had access to, which matches with a long and arduous journey 
(although this may just be an artefact of the particular guides we have looked 
at).
as Rohan has said, it was a long way from town, and given the density and 
diversity 
of the raptors that we saw on our short visit to Broome, I doubt very much that 
a 
caged bird would make it out to Roebuck Plains Station.....
i think the sighting highlights the great work being done by the staff at the 
Broome 
Bird Observatory, and does credit to their outstanding commitment and expertise
regards
Carmel Flint
