Just wanted to get some feedback about which Australian birds will attack the Phantom 3.

Most I've encountered are curious at the most.., however my P3P did return with a splatter of blood on the prop and arm once.
Noticed ants crawling in the next day, probably eating small bits that made it inside. Makes me wonder what it was.

Might have been a Vampireroo that attacked your drone....You know, one of those Kanga's that have been bitten by a Vampire that can now fly..hence, Vampireoo!..

The birds are not the problem, it is the Drop Bears, they can crush your drone flat.

I found at my home even little Swallows will attack my aircraft, as it is to0o near their tiny nests. I think you could get almost any bird attacking, if you go near their nest.

Birds attack? I haven't heard that which type of birds have a special interest on the drone. But it might be very dangerous for the birds and drone, so it's better to stay away from that area.

Magpies can be the worst around nesting season - July-Sept.
Butcher birds and Kurrawongs can also get territorial and try to get rid of a buzzing intruder.
There's also a youtube video of a Wedgetail eagle dispatching a Phantom.

I would think most birds of prey and any birds known to be territorial I've had black kites demonstrate a bit of interest but no actual attack.
