I'm aware of my GCC's basic vocalizations and meanings (more or less) for such as: his contented beak grinding, happy ratcheting growl/purr, warning "don't do that" squeal, and his piercing whistle of unconstrained excitement.
However my male GCC has started to make a new sound, only in the dark in the evening and early morning; it's a quiet, long drawn out squeal like you'd make sucking air through your teeth. It varies in pitch, sounds extremely eerie and I would hate to think it means anything serious. I think/hope it may be his "I was asleep, why did you wake me to tell me goodnight/goodmorning ?" complaint.
Other than a custodial requirement; I feel I should make an effort to understand his language if I expect him to understand mine... after all aren't we supposed to be more intelligent ?
Any ideas ? Any other interesting GCC noises, or vocalizations ?
