I have had Jet, my Cockatiel, since September, and Skye, my Budgie, since December. One thing I have noticed with regard to the two birds, is that the Cockatiel craves more attention and loves to be held, pet, and climb all over me. My Budgie, who is finger tamed and friendly enough, craves no attention, will come out of his cage but has no problem going back in as if he'd rather be back in there. My Cockatiel is the total opposite. He has a temper tantrum when I leave the room. lol My question (and I know this is generally as all birds are different) is do you think Cockatiels are more social and attached to their human friends. The other weird thing is I've always heard that Budgies are generally more aggressive than Cockatiels. While my Budgie could care less if I'm around, he is in love with my Cockatiel (who wants nothing to do with my Budgie). Would love to hear some opinions.
