We have a parrot, situated in my room at the moment because it seems to enjoy the sun alot more. (As well as that, it is reasonably large area adjoining to the upstairs rumpus room) so it spends usually 2 or 3 hours during the day out of its cage, usually when my mums doing the ironing upstairs, and usually 1 or 2 more at night - more on weekends and when its rainy. In winter when I don't have to leave my Windows open, I just generally lock the door and let it go in and out of it's cage as it pleases during the night, only problem is if it's bored it usually rips at my hair.
But they are high mateinence, and as Rugby_Cyrmu said, very jealous - there is hell to pay when i'm seen patting the dog or feeding the fish. It seems to know about 20-25 words, i'm not sure if this is the norm, but it took awhile to learn words, but as soon as it learnt to the basic wolf whistle, things suddenly sped up and it started mimicking things like ordinary car noises along the street and my mobile phone, until it gradually began to form simple words like "Hello" and "Shut Up"... now it mimics specific car noises, whenever my dads car pulls up, it will make that sound, and whenever my Mums scooter pulls up, it mimics that sound as well.
