Droppings?

I'm trying to help Lisbeth identify these. She thinks that they are probably droppings of some kind.

They are on the path by the bamboo and on the path next to a Pavillon de la Musique. Just those two places and nowhere else.

They are sloppy and look like regurgitated fruit, so she doesn't think it's owls. She wondered about bats but each dropping is as big as a bat's body in itself, so it can't be bats. Any suggestions?
