Bold Eagles: Angry Birds Are Ripping $80,000 Drones Out of the Sky (cetusnews.com)
schwit1 found this story in the Wall Street Journal:
Daniel Parfitt thought he'd found the perfect drone for a two-day mapping job in a remote patch of the Australian Outback. The roughly $80,000 machine had a wingspan of 7 feet and resembled a stealth bomber. There was just one problem. His machine raised the hackles of one prominent local resident: a wedge-tailed eagle. Swooping down from above, the eagle used its talons to punch a hole in the carbon fiber and Kevlar fuselage of Mr. Parfitt's drone, which lost control and plummeted to the ground... "It ended up being a pile of splinters"...
These highly territorial raptors, which eat kangaroos, have no interest in yielding their apex-predator status to the increasing number of drones flying around the bush. They've even been known to harass the occasional human in a hang glider... Camouflage techniques, like putting fake eyes on the drones, don't appear to be fully effective, and some pilots have even considered arming drones with pepper spray or noise devices to ward off eagles.
One mining survey superintendent said he's now lost 12 different drones to eagle attacks, costing his employer $210,000. Another drone was actually attacked by nine different eagles, and its pilot estimates eagles are now attacking 20% of all drone flights in rural Australia.

I hope the eagles knock each and every one of these machines out of the sky. I hope it ends up costing these companies millions, and there's not a fucking thing they're going to be able to do about it. Drone operators/owners are some of the most selfish, self-entitled assholes around, and every time one of them loses one of their drones, I cheer. Good riddance.
The world's burning. Moped Jesus spotted on I50. Details at 11.
wedge-tailed eagles strike at speed with incredible power as they rely on this to stun/kill, they are also very large birds which can weigh up to around 6kg and while the rotors may do some damage the drone will still be destroyed by the impact. They are also a protected species
Best of all, these eagles are listed as endangered and are protected by Australian law. In fact IIRC, the sections of the law that pertain to endangered species impose a "strict liability" standard on actions that injure a member of that species. That means you don't even have to intend to inure one of these eagles. Just being careless can get you serious prison time.
So pretty much those drone operators have to suck it up.
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.
Nothing a 10 gauge goose gun can't fix.
It's a protected species. Hope you like spending time in jail.
more power to Mother Nature.
drone ops...tossers and wankers.
OP is correct that birds are immune to capsaicin (the chemical in hot peppers which makes them "hot"). Speculation is that pepper plants use the chemical as a way to discourage land mammals from eating their fruits, thus guaranteeing their seeds would be dispersed more widely by birds. Pepper spray isn't going to do squat.
What you're describing is cartwheeling. It's a show of trust between them, and is an integral part of courtship.

Worried about the eagles? Mining companies generally do surveys not to enhance a species' habitat but to destroy it. Oh, we're not allowed to harm eagles? NP, we'll just mine the shit out of their territory, and they can sustain themselves by preying on the leftover boulders. Yummy!
