The spookiest sounds that Moses has made was one dark October evening about dusk I was alone in a huge house with only my computer on and low and behold "someone" was sharpening knives in my kitchen! He only heard that sound one time and then said it to perfection. Scared me to death.
When I worked tech support for Toshiba - I was working an issue with an owner, and in the background, I kept hearing a burglar alarm getting armed. I asked what it was, and he explained that it was their parrot, imitating the burglar alarm being set. He told me to wait a minute, and then I'd really hear something. Suddenly, there's a siren going off in the background, all whoops and wails - it's the parrot. Guy tells me that it's really fun when the bird decides to do it in the middle of the night.
great stories. I would love to one day own a parrot, but I'm a little intimidated by their life span.
