In my youth in the UK I used to hang out with falconers.  Their Peregrines would take out Grey Herons with ease, and usually in the air. I suspect a Bin Chook would be heavier than a Grey Heron but length and wingspan possibly the same.

This morning I woke to find a Peregrine Falcon in the process of killing and then eating a White Ibis on my driveway. I'm surprised, but perhaps I shouldn't be, that such a large bird would be taken by a Peregrine.

I presume that the Peregrine most likely took the Ibis in the air, but by the time I saw them, they were on the ground.
