I have quite a number of books on parrots and other birds... none of which explains why my African Gray bobs his head. It seems like a friendly gesture... but I would like confirmation.

I have noticed our blue fronted Amazon does it too, but it isn't the same thing when he does it.
Thanks :-)

Head bobbing, when done quickly and in short spurts means "I love you." When done slowly, rhythmically and endlessly it means "I've gone permanently insane from a lack of attention from humans or a total lack of interaction with other birds."

I often see one or more birds doing the latter of those in pet stores (usually larger birds like macaws) and it breaks my heart every time.

How did you come to that conclusion?

Here's my sun conure enjoying corn chips and doing some head bobbing:

I have heard that it is a feeding thing.

The feeding reflex isn't the same thing. As a 11 year AG I'll tell mine does it when she is happy. When I give her a peanut she'll take a bite, do a head bob, take another bite, do another head bob and repeat until the peanut is eaten up.

Your bird is expressing friendliness. If he does it when he's nervous, he means that he's non-threatening.
