Cast query

["Philip Veerman" <>]

Could be one of several bird species. I took the question to be about the close location of these things around the stone. I wonder if the stone is incidental and the answer lies in the presence of a suitable favourite perch above. Certainly some birds develop a habit of using the same location for doing this. Mammals do things like that to mark territory but I don't know that birds do. I'm not suggesting it is a mammal.

I have often seen such things,
with beetle wings evident,
I have always assumed them to be Currawong pellets
(regurgitations).
I do know they regurgitate undigested kernels of plant
seeds, for example (which incidentally, are great for germination of native
plants - but be prepared to weed out the weedy plants).

In January on a track in Campbell Park, I noticed a number of apparent casts heaped around a stone (see attached photo)- mostly containing insect parts I think - and was intrigued by the number possibly implying some sort of regular use of the stone? .
Any suggestions re bird involved? (The original larger photo has much better cast details).
