This has nothing to do with peregrine falcons, which are falcons, not eagles and are not being used here. Golden eagles do not usually go over 300 km/hr and 320km/hr is the _maximum speed_ they will hit. Saying 'several hundred', for something that is almost always in the 200s, is disingenuous. If someone has $2.75, I would not say they have 'several dollars'. But that gets into a discussion about if two is considered part of several and that is completely pointless.

In any case, they most certainly cannot 'generally' avoid rotors. I have seen birds of prey - as well as smaller birds - attack and/or collide with UAVs. I have never seen a bird escape uninjured except with a small quadcopter with plastic blades. If someone was orchestrating a terrorist attack they would obviously need some sort of payload, and would not be flying a palm-sized plastic-blade quadcopter.

I think eagles are cool and they're clearly majestic creatures. But using them to catch a set of spinning blades in the sky - when a bullet works just fine - is really stupid.
