Of course, a far simpler countermeasure would be to fly your drone for malicious purposes at night. As far as I know, there are no birds of prey that hunt other birds at night. Could owls be trained to take prey in the air despite being adapted to hunting rodents? I don't know.
Haha, that is crazy! It is a strike against a stationary target, however. I have yet to see an owl pick off another bird in flight. After all, why would any other bird be flying around in the dark?
