Drunk Parrots? Luxury!
Here in Sydney, we get drunk Flying Foxes.
For the unenlightened - Flying Fox = Fruit Bat. These aren't cute little critters; they are 1m wingspan evil-smelling loudly screeching bastards. That are also somehow 'protected endangered species' despite there being about 250,000 of them in Sydney alone.
Flying Foxes LOVE Mulberries, especially mulberries that have fermented on the tree. A drunken, screeching ball of sharp-clawed ferocious anger smacking into your face at speed is one of a Sydney summer's prime experiences.
Oh, and their poo gets stained a deep purple by the mulberries, and is the consistency of quick-setting epoxy resin. It is not fun to get it on you, your car, your house, your timber deck, etc.
For tourists, the best place to see them is the Sydney Botanic Gardens, where about 80,000 (yes, that many) have taken up residence in the past decade. The are destroying the gardens, and the area they live in reeks of rancid flying fox poo; the Gardens Trust isn't allowed to remove them because they are an 'endangered' animal. Animals seem to be worth more than rare plants!
Take a raincoat you can throw away if you want to see them.
