I'm assuming the aerial defense force is summoned by playing "ride of the Valkyries"
To see an intruder savaged by a Macaw would fill me with amusement
The main arial attack would actually be Kelly the evil YNA... he is truly a vicious thing that would happily fly and attack anyone (including me). It's a shame we did not get on video the one time Kelly flew at me to eat me....
Our TV area is built in and has two drawers and cabinets under. The one side I keep the towels I use for bird 'stuff' - like there is always a towel under the two chairs where Max sits and eats, he is mostly potty trained (his own OCD doing), so putting down the towels is the easiest and quick clean up way. But Kelly has decided that the towel cabinet is his 'nest' and he gets nasty protective over it. Our home is fairly open with high ceilings. Kelly was on the large java playstand in the breakfast nook area (which is a bird stand nook for our family), and it's a straight line view to where the TV is. Without thinking, I opened the cabinet to get a clean towel with cleaning Max's area. Kelly decides I must die for invading his 'nest'... now keep in mind, he's a heavy turkey bird and does not fly well, he pretty much can take off and fly in a straight line slowly losing altitude (he gets no lift)... My back is to where Kelly is and I am walking towards Max's hang out spot and I hear the flapping wings, but my Ivory (bare eye) is a super flyer and is always buzzing around, so never crossed my mind it was not her. I hear Victoria yelling Mom, but again, not registering it's Kelly on his for me.
I was thankfully wearing a hoodie that day, and had just started to turn around to see what she was yelling about, so Kelly landed on me at the side of the hood just missing my neck and cheek. The spot I'm standing where he lands is just next to the two steps that go from the upper to lower living room area, so I find myself trying to flip him off the hood without him getting my fingers and I can't see him as I kinda bent so he was hanging from the hood and not climbing easily to my face. In my movements, I step down the those two steps and find myself kinda spinning while trying to flip the evil monster off my hood. In that spinning movement, I find myself getting closer to the three steps that go from lower living room to the vestibule / entry area. By this point, I am debating using the wall to knock him off.... but apparently I am twirling and flipping the hood while trying to get him off without hurting him. As I approached the second group of steps, which I don't realize, I think Kelly decided to abandon the ship before he ended up crushed as I was about to go over the edge...
Keep in mind, with this whole thing, I have MS, so my balance is not always the best, so that adds to the amusement of how off kilter I've gotten from trying to avoid being eaten. Thankfully I ended up on my feet going over the steps and did not injure anything, tho my body was angry at me for days... Still not sure what took Victoria so long to get there to help, but I am guessing she was too dazzled by my flailing and spinning

We both about peed ourselves laughing after realizing that no one was hurt and tho he tried, no blood was involved.
And sorry, no I'm not open to recreating that event for video sake! But, it was pretty funny looking back. It would be amusing if someone broke it and we did get the chance to toss Kelly...
I think both Max and Titan would be more likely to scream and would only go into attack mode if the person got close to me or Victoria.
