That
would seem notable for two reasons: if indeed they are seeking to dislodge
owners of an existing nest and the timing is very early in the year. If we get
other early records, it could be indication of a change to their annual
patterns and maybe a climate change feature. Certainly potentially something of
interest. So I looked at Birds of Canberra Gardens V2 to see if there is any
updated information with the extra years of data now available since The GBS
Report. No surprise, there is no mention of it beyond what I wrote in 1999 and
not even any monthly graph of this: one of the most notable results of the GBS
(so much so that it is on the cover of The GBS Report, apart from of course the
opportunity to use my painting of the bird on the cover) .
The
behaviour Mark wrote of but the raven seemed totally
disinterested is also in contrast to what I observe most years between
the Pied Currawongs & Aust Ravens who battle out for 2 or 3 weeks as to who
gets nesting ownership of the big tree in my yard. Both species get very
involved in the fight.
As
referenced in The GBS Report and my much earlier paper:
(1991) ‘The monthly pattern of records of the Australian Hobby Falco longipennis in
Canberra, A.C.T.’, Australian Bird Watcher
14: 70–72.

Good morning all,
I have just come back from purchasing tickets for the Raiders
home semi final on Sunday and in the car park opposite the entrance to the AIS a
pair of Australian Hobbies was trying valiantly to dislodge an Australian Raven
from its perch just below what I assume to be a raven nest that the hobbies
would like to use. There was some spectacular aerial activity on display, but
the raven seemed totally disinterested.
Cheers,
Mark
