Recently I observed a Bower's Shrike-thrush killing an arboreal snail
[Rhynchotrochus macgillivrayi] by tapping it repeatedly on a rock.  It then
extracted and ate the contents.
I cannot find reference to such behaviour in shrike-thrushes or whistlers.
The crustacean dietary items of the White-breasted Whistler I suspect would
be dispatched in a similar manner.
Any help gratefully received.
