I read this forum aloud. Then I comment aloud on it in an excited tone. I also stick them on my shoulder (no need to wait, poop washes out, or if it dries a little it can be carefully lifted upward and leaves no mess). Whoever's on my shoulder rides around while I clean the cages, refill and replace food dishes, etc. I talk the whole time about what I'm doing or seeing. "Look at Torrie! She wishes she were up here like you!"
For play, I keep a basket of toy parts like bitty bagels, beads, paper shreds, and foot toys. I play in it or stir it around, taking one out and examining. Usually the bird takes the lead and grabs it. Sometimes he'll initiate the game, like taking the toy from me which turns into either "give" and hand it back and forth, or "keepaway" (where I say give me that! And pretend to grab it.) Sometimes I let them see me drop a treat in among the toys. Sometimes I lay out a few toys and ask which one, and if he doesn't choose one I start picking them up and playing wiht them, and he then plays too.
A couple of them like to beak wrestle. One LOVES that. I crawl with my fingers very slowly and he puts his beak down and the monster (my 2 fingers) grabs his beak gently and wrestles it. He puts it down there again and again for that game.
Target training is da bomb, and you can do almost anything once they get it. It really is a way of bonding with them. Even my ones who are not target trained play the Perch game. I tap a perch and they fly to it (and get a reward, like a bit of millet that I hide behind my back). Then another perch, reward with millet again. They all like this game and they know the word Perch -- another "game" that makes it easy to move them around if you need to.
You can see that I should be preparing the house for a major remodel and instead I hang out in the bird room.
