I have been unable to access the pictures but I would suggest this scenario:
Falcon attacks roosting Frogmouth at high speed. Kills Frogmouth. Falcon then strikes against another branch of the tree with fatal results.
A young Collared Sparrowhawk dashed into a branch and was killed some years ago in our back creek flat. No marks on the body. No sign of prey – perhaps it dodged.
