What are the best petting spots for macaws?

[5 feathers]

My B&G Macaw loves petting, especially on his ear. What are other spots to make him comfy? Are there bad spots to touch a macaw? Is touching a macaw too much a problem?

The head only

Head, neck, feet & beak. Otherwise nothing else. JaKhu likes me to touch her tongue & loves head & neck rubs. I rub feet, so they aren't fussy about nail trims.

For baby birds, I touch them all over so they get used to being handled. As they get towards a year old then I leave it to the head and the feet. My baby greenwing would lay on her back and sometimes I would rub her belly, but I stopped as she got older.
