Hi from Dublin
This account reminds me of an incident I saw on the North Bull Island, Co. 
Dublin last winter. An immature Spoonbill was sleeping on the mudflats, minding 
its own business. There were several Hooded (Carrion) Crows in the area and, as 
we watched, we saw one of these birds circle the sleeping Spoonbill. It then 
took three or four hops towards the bird and pulled on its tail feathers. The 
Spoonbill woke up and moved off. The crow then resumed feeding, ignoring the 
Spoonbill which had landed 20 metres away. We believed at the time that the crow
was simply up to mischief, as there was no other reason for such behaviour. 
Perhaps the same can be said of the Raven with the Cockatoo's!

*****************************************************************************
I saw a strange sight yesterday.
     
A flock of about 20 Sulphur-crested Cockatoos was feeding on the ground near 
where I 
work in the city of Canberra.  An Australian Raven (I call them crows:  'The 
Crow and 
the Cockatoo' sounds better than 'The Raven and the Cockatoo') walked or rather 
waddled 
slowly into the flock, feeding (probing the ground with its bill) as it went. 
The 
cockies ignored it and it ignored the cockies, even though they were as close as
one 
or two metres apart.
     
The crow then did something remarkable.  It was behind a cocky, less than a 
metre away. 
It took a few rapid steps forward and grabbed one of the cocky's large, central 
tail 
feathers in its bill.  It hung on while the poor cocky flapped its wings, 
hopping up and 
down, calling loudly, obviously trying to get away.  The crow stood its ground, 
firmly 
attached to the end of the cocky.  The result:  the cocky got away, leaving the 
crow 
with a feather in its bill and (presumably) the cocky with a sore bum!  It flew 
about 
two metres to a post, perched on it and screeched loudly!  The crow spat out 
(oops, I 
mean dropped) the feather and resumed feeding on whatever it was after in the 
soil.  The 
other cockies ignored this altercation.
     
What, pray, was going on?  
*    The crow could not have seen the cocky as a source of food.  
*    There could not have been any competition between the two species for food 
or 
territory or other breeding resources.  
*    Perhaps it was simply play/inquisitiveness on the part of the crow (what 
does it 
feel like to pull a tail feather out of a feeding cocky, it may have wondered?).
     
     
Any suggestions?
     
David
