My bird just got on my finger and started doing a little jig or something. Just wanted to know exactly what that is or means. It is silly and it tickles. I have a video of it posted in my facebook and the link is below.
Like FaeryBee said, it doesn't seem like he's doing anything unusual, he ops on and off your finger, tries some millet and gives your finger lovebites (or maybe he's trying to eat your finger, mistaking it for more millet muhahah). Looks normal to me :3
