I love my bird to death ... every time I come home and he sees me , he chirps and hops down off his perch when I go over to his cage . He preens my hair and nibbles on my fingers ( sometimes he bites , but I forgive him ) . I was reading in a cockatiel book I had upstairs that they only scream in one - syllable notes when they 're ignored , and I felt bad .

What is probably true about this bird ?
It cries when it wants to be petted .
