I've had a baby cockatiel for several months now who exhibits very similar behavior with me. It can sometimes be a little irritating trying to deal with the noise as she is incredibly needy, but she's still only a baby. As you say though, they are very affectionate animals, so there is something strangely comforting about how much they confide in you. Love my little lady ❤️ https://imgur.com/a/Padki9F
