Except for my bourke parakeet who has no interest in human interaction (especially lately, having to flush her sinuses! and give daily supplements - poor girl!), I've been able to get all of my birds to interact with me in some way!
I honestly don't care if my birds desire my interaction or not as long as they are happy! If they want interaction, then I'll interact with them!
Over 6 years ago, I had a small flock of budgies. Only five. All adults, all flighted! Non tame! As an "experiment", I decided to see what I could do with this flock.... I started by feeding them by hand.

I eventually was sitting just outside the cage with my hand on the other side. The budgies came out of the cage to eat from my hand. They were nervous about it, but monkey see, monkey do!
A month later, I was standing four or so feet away from the cage, standing, and with food in my hands!

That was essentially my experiment. To see if I could get 5 untamed adult budgies to fly to me. Well, I had a cockatiel who was watching, so she started following me around the room. I didn't know why she was following me. A couple of times she got frustrated with me enough to momentarily land on me! This is new behavior... then it clicked! Offer food to the bird! She was nervous at first, but she became comfortable with the idea! (hand raised tiel that was owned by a boy who grew up and discovered girls and sports so got ignored)

Have I mentioned monkey see, monkey do? Sure enough, another tiel saw me doing this behavior with the first tiel, and she wanted to be included, too! She was very hesitant about it, but she still wanted to be fed! (don't mind the fact that she could have easily eaten from the food dishes instead!) (this tiel has had at least 3 homes prior to me, her mate was supposedly killed by mice, it was not a good situation)

In time, she too became comfortable and confident in this behavior! This time, we have pellets!

And the other cockatiels had to join in, too... (Casey, handraised and tame cinnamon pearl pied hen, Pistachio, most skittish cockatiel, father of Sunshine the first tiel shown, was taken out of an animal shelter with his mate years ago and Tomi Girl, a pied hen who was found in someones yard then they nearly starved her to death because they "simply forgot to feed" her.... not to mention the fact she was also on eggs and over 40% underweight)

Since moving, I haven't continued this interaction, but I did enjoy this simple interaction with my hands off birds!
