Largest flying birds are right now are: - In the west it's the Andean Condor - Globally, the african Kori Bustard. Now, birds can be tough. The prime example is the conflict between the Australian Army (including the Royal Australian Artillery) and 20,000 emus known as the Great Emu War. The outcome was a decisive Emu victory. https://en.wikipedia.org/wiki/Emu_War https://en.wikipedia.org/wiki/Emu_War Some people argue that this was not a conflict as it is frivolous to consider Emus as a military force. However the fact they were capable of the formidable achievement of defeating a regular army proves they can, and this is also not the first conflict involving animals (e.g: https://en.wikipedia.org/wiki/Gombe_Chimpanzee_War https://en.wikipedia.org/wiki/Gombe_Chimpanzee_War). Note that emus cannot fly.
