I am working with a Blue and Gold Macaw that is just under 1 year old. Unfortunately she was clipped before she learned to fly, so I am thinking that could be part of the problem. I have been watching YouTube videos with macaws climbing ropes and climbing around at all angles, doing tricks like role over, and hanging upside down. But it seams like the she does not do things that require her body to not be level. She has multiple natural perches in her cage and she will go from perch to perch, but I don't seam to remember her climbing on the bars the way other parrots do. I am doing toweling desensitize training like Barbara Heidenreich and it is along fine as long as I am sure to hold the bird straight. I have been looking at role over tricks and hanging on my hand by the feet tricks. Even in the middle of a flat table I pushed on the bird so that she is just a bit off balance and she became highly annoyed when I only put her off balance by only a small amount. I stopped doing this as soon as I realized it was bothering her. I started trying to desensitize her to being off balance with the following method. I sit down on a bench and hold my torso straight up and down. I then hold her against my chest and pet her on the head. I then start to lean back on the bench so that the bird and I at the same angle. I usually don't have to lean back too far before she becomes nippy. I will then straighten back up and keep petting her on the head so that she will calm. I've had cockatoos who will move to a new perch by grabbing it with there beak first then transferring their feet over. This will put the bird's body at an odd angle, but the bird doesn't seam to mind. I have seen this video with a fully-flighted macaw on ropes high up in the air transferring and swinging. Is it a thing that young Macaws will refuse to put there bodies in a non-horizontal position? Does it happen when birds that are clipped before learning to fly? I have a few ideas I haven't tried yet. I have the bird target trained. I'm thinking about getting a bushy piece of dead tree and mount it firmly. I can put her on one Branch. I will target her to different places and see if I can get her to climb around on uneven parts of the branch, or get her to climb from branch to branch. Another thing I am thinking about is to mount a rope to a firm perch and target her so that she will need to put one foot on the rope and one on the perch to reach the target. What do you all think?
