Why should it sacrifice itself? There are more than fast-flying kamikaze drones. Smaller spotters or all those improvised models based on commercial quadrocopters with an AT warhead are nice targets for a properly sized bird of prey coming at them like they would hit their regular prey… fast and from top.

In fact there were several project world-wide to actually train birds to hunt down drones. Most were abandoned as fast spinning rotors can be a danger to claws when they get unlucky… but still it’s perfectly reasonable to expect a big owl, eagle etc. to down a drone.

yes you can. dutch police and probably some others trained eagles to take down drones, but project was shelved because of lack of interest
