Maybe just me, but when I opened that link, my computer froze and I had to switch off to restart.

a lot of the picking is to do with socializing and finding out who your mates are in the crew.
Can u imagine people doing that.

Fleas, it's protein!!

They are picking fleas etc from each other and also general grooming to develop friendships and establish the social hierarchy.
