We have one of those bird clocks - the kind that each hour sings a bird song - and a cockatiel named Spike. Spike likes some of the bird songs on the clock, and he truely hates others! The song sparrow chirps make him screech in protest for at least 10 minutes. Other song, though, produce many happy mintues of singing and trying to coax the birds to sing back to him. He's trying to imitate some of the songs he hears.
The funniest thing he sings is the theme song from the Adam's Family - including the finger snaps!
He's a riot - except when I wake him up too early in the morning - he preferrs to get up at around 10 a.m. - and no worms, thank you very much, indeed!
