Is there such a thing called Body Touch Training where you try to touch around the bird's head, wings, feet, and back to get them to be more comfortable with physical contact with you more like them not minding you to touch them? I know you can't pet them due to hormonal triggers but saying if there is such a thing is all and how to start off. My bird is fine with head scratches when she wants them the most on her own but like her to get used to me touching her without any fear.
Yes there is but you do have to be very aware of their body language, a bird allowing you to touch anywhere other than the head is a very cautious process that can quickly turn sour if you start pushing their boundaries. This post is talking about them letting you open their wings but the same sort of concept applies. Start with the hands far away where they’re comfortable, reward for comfortable body language and very gradually work your way closer, don’t come from above them and don’t come from right below them you’ll want to be either at their side or a little bit below eye level so they don’t see you as as strongly of a threat. When you are able to contact them don’t start petting or hold your hand there too long, start with a gentle touch and work up to longer durations very slowly. If the bird every pushes you away, lowers their body, opens their beak or shows other signs of discomfort remove your hands, we want them to know that using these methods of communication to tell us they don’t like what we’re doing works, otherwise they will escalate to biting since it’s the only way to make us listen.
