Aberrant Raven?

["martin butterfield" <>]

This is a possible worry.  The description of the placement of the grey, and
the behaviour of the bird, made me instantly think of a House Crow (with
which I am cery familiar from East Africa).  I recall that there here was
another recent report of this vermin from Victoria.  It would be good to get
the appropriate authorities on to tracking (and deleting) this bird asap.
