ALL pets are pretty much unpredictable, all except like fish or something. I thought I was building great relationship with my boyfriends birds, one being an obese birdie named Binkie who was on my boyfriends arm last Saturday and I was standing next to him tickling his tummy and pulling my finger away and Binkie would giggle and "dance". on about the third tickle he catches my finger and bites!!! I was bleeding and still got a fresh looking mark there on my finger. But boyfriend kissed my first birdie booboo and made it all better
