They do seem to give a choked screech every now and then. The first time I
heard it I thought that a bird might have had something caught around it's
neck till I realised that they all made the same noise. It sounds like that
they may be trying to imitate the Glossy Black's.

On the topic - broadly speaking - of Yellow-tailed Black-Cockatoos, I
heard a call yesterday from one which I have never heard before (and I
see and/or hear them virtually every day). It was a cackling sound
almost like a deep-voiced wattlebird, quite different from anything in
the usual repertoire. The bird was quite animated, perhaps agitated,
while producing this call. Is anyone familiar with this call and its
possible significance?

My father lives at Old Bar and fishes for Ludrick at Manning Point. You
see
this behaviour on the other side of the river on the road to Harrington.
I
have also seen the same on the Old Bar Rd about 4Km's towards Taree from
Old
Bar on Chain Rd. I used to see them on the Salt Water Rd from Old Bar
but
this area is now built out. They seem to be happy to feed in the same
areas
with little or no interaction between the species.

We've just arrived back from a fabulous holiday break near Manning
Point, at
The mouth of the Manning River, Mid-North NSW.
Each day a flock of 6 Yellow-tailed Black-Cockatoos flew into the
immediate
Area around our cabin to feed on the seeds of Forest Red Gums
(Eucalyptus
Tereticornis) and various Banksia species. Interestingly, on the 2nd day
of
Our stay only, three Glossy Black-Cockatoos flew into the same area to
feed
On the seeds of Forest She-oaks (Allocasuarina torulosa) while the
Yellow-tailed Black-Cockatoos were still feeding.
This is the first time I've seen these two species feeding in the same
area
At the same time. They were quite clearly two separate feeding groups,
Feeding on different food items, and there were no obvious interactions
Between them, except maybe responding vocally to each others calls. I'm
not
So sure how common this association is and I'm interested to know if
anyone
Has observed these two species feeding together at other locations.
A 10-km stretch of a relatively secluded surf beach was just a 400-metre
Walk from our cabin. On Days 5, 6 & 7 of our holiday (6-8 January 2009),
the
Surf was low and beyond the breakers the water was relatively calm. We
Enjoyed watching small numbers of Little Terns dive for fish just beyond
the
Breaking waves at these times.
