SO IT TURNS OUT a peacock meows. I feel like my primary school education was somehow lacking since I didn't know a peacock meows, but alas, it does, in a register somewhere between a cat and man in falsetto. I can attest to this because one decided to meow quite loudly at six am, after walking on the roof and scaring me into thinking I was about to be attacked by burglars. They also eat rodents, which I guess makes them the cats of the avian world.
