I know grey owners who say it is really easy to tell the difference between the back off head bow and the scratch me please head bow, but, seriously, I can't. I also know MANY owners who tell me they can't, either. Dr. Friedman said she personally can't see the difference, either, but she knows lots of people who can and lots of people who can't. I also know grey owners who swear that greys do this on purpose to lure unsuspecting strangers to them so they can bite them, lol. Personally, I think it is that the difference in the postures is hard to read, but, honestly, none of us can really know what goes on inside those heads.
I've never been bitten by a cockatoo, and I don't want to be!
This morning I was saying silly things to Ashlynn while I was feeding everyone, and she was giving me the evil eye. There is nothing in the bird world that looks more seiously disgusted with you than the grey "evil eye". It's not a leave me alone kind of thing. It is like the evil eye a mom gives her kids when they've embarrassed her beyond belief and they KNOW when she gets them alone life isn't going to be very good.
Grey's are VERY interesting, but, wow, they keep you on your toes!
I'll try to get a photo of that look some day, but with my photography skills, don't hold your breath.
DALLY and/or Daisy - and really lots of others of you great photographers - you need to have an opportunity to photograph some grey faces. They are sooooooooo expressive.
All the South American birds thought my silly actions were cause for celebration and joined in being silly with me.
