To his red footed cousin:
Just looking at a tv documentary about the Blue Footed Booby, where I hear the commentator say that Booby comes from Spanish bobo.(so far so good) But that this means clown. Not 'stupid fellow' as Wikipedia sold me. That the word refers to the way the bird lifts its feet and I have indeed seen that the Blue Footed Booby walks like a clown. Very funny, not stupid.
Wicked wiki.
