What an interesting observation!
Many bats are killed by birds, not just owls but also things like Jays
(think Butcherbirds!). Bats are often easily caught up with by birds, but
they can have an advantage in manoeverability and perhaps also from being
able to easily know where the predator is even if they cannot see it. But
sometimes this does amaze me a bit. How did a Boobook catch a Miniopterus?
Those bats are fast and show an extreme ability to change direction
suddenly. I suspect for whatever reason, it wasn't a fair fight!
No idea what your bats were. Quite unusual to see groups hunting like that
in Aus. But given that it was an oval, maybe it had been watered or
something and there was some insect event going on.
Cheers, Chris.
