What is the noise vomit bird? The cockatoo. Sure, they look handsome but holy shit is their screech unsettling and loud. I presume it's some sort of benefit to do it; maybe it's to put other birds off being around because the cockatoo is the equivalent of someone on a rage bender drunkenly cursing the street?
I have PTSD. One was about three metres from me in a tree when it cooked off and its unpleasant screech pulsed through my body and head.
Hilariously some people enjoy the cockatoo. So do I---as a concept. I just hate them in real life being anywhere near me.
It may too be a Canberra thing. In our third house we had a roost of them in a power pole junction and they'd raise unholy hell against us at dawn and again at dusk.
Cockatoos; they're history's greatest monster.
