No, not a tunefull whistle, but a single note, repeated every 2 seconds for half an hour. Nothing stops him. He's a yellow crowned amazon, semi tame (no touching allowed but will take food and have conversations with me). He has a girlfriend and is very happy in an aviary with 3 other amazons. The whistling thing happens twice a day with no apparent trigger. It's like a beep from a microwave, half a second long, high pitched, but unlike the microwave which does 5, he does about 100 of them (1 every 2 seconds for half an hour). Any suggestions how to make him stop? I've tried saying "quiet", and shouting "quiet!!!", both make him quiet for about a minute, then he continues. I've tried whistling a tune every time he does it so he does that instead, but he's not interested. He doesn't seem to want attention, although he will go quiet when I go over and talk to him, then starts up when I walk away. I obviously can't talk to him 24 hours a day. TV doesn't work.
