Back in the day, white cockatoos would appear in thousands in the tropical North of Western Australia, & sit on the Boab trees,(the trees are the same species as the African Baobab,) making them look like they were in flower.
That was harmless, but their favourite "party trick" was to cluster in huge groups on the pole route (phone
landline) South of Wyndham WA.
They would swing back forth, until they managed to entangle the wires.
This would cause feedback on the carrier telephone system.
The incoming & outgoing channels were on separate frequencies, but get enough coupling & it would overwhelm the filtering, so the whole system would go into oscillation.
This always happened just when atmospheric conditions were at their worst for the backup HF Radio system.
Back in the present, my major problem is Ibises stomping around on my roof.
I'm too old to climb up on the roof & yell at them, throw stuff, or shoot at them (even if that was legal, I'd probably miss the Ibis & pot a TV antenna installer in the next street).
