Congrats Dan on posting the 11,000 message to the archive. That
should keep new people busy for a while.
I have not heard a Raven beak click but that does not mean a lot.
I note the context of that click in response to an agression by
another. This I have seen common in Owls and it could be the Raven
is giving the owl response "in context". As ravens mob owls, it
would be expected that a raven has heard that response before.
Parrots on the other hand beak click in all sorts of situations such
as "play" and Ravens are pretty good in the "play" department as well.
