I must admit that I'm guilty of such trickery on occasion. One example involves Zaffer, my Hyacinth. He is often impossible to peel off of my arm or shoulder. The problem emerges whenever I require the use of both of my arms for a task. I find that in such cases it's easier to simply say to my tenacious friend, "Zaf, shoulder!" He will then happily move up to my shoulder, which may render adequate limb freedom for my current needs. But there are other times when the only option is a full extraction from my person of my clingy blue buddy - such as when I require the ability to move within a cramped area.
Enter the deception. All I have to do when Zaf is firmly anchored to part of my body (and in "lock" mode) is say to him, "let's go clip your toenails." Once I do that, he will immediately, and vigorously, leap off of my arm or shoulder and onto whichever structure or surface appears the quickest path away from me. It works like a charm!
I should also mention that Zaffer will always allow me to clip his toenails while he sits on a T-perch. He usually even hands me each foot willingly. But that's only after he has resigned himself to the fact that he's been placed in the posture and the procedure IS going to happen... i.e., that he has no out. If ever he thinks he may be able to escape before then, he'll embark on the aforementioned rapid beeline away from me. Conveniently, that tendency in him serves as a perfect tool for me to free myself from his grasp
Do any of you ever use similar trickery techniques on your birds?
