great tit

i was watching animal planet today and it was showing a bird and the birds' species name was "great tit." i heard the name but it kind of slowly processed through my head. then i was rollin'. then i googled it just now and went on http://en.wikipedia.org/wiki/Great_Tit nd it said shit like: "japanese tit,"  "cinereous tit." lets just say it says the word tit a lot. i have one question? who the hell named this bird? sorry 2 questions? why the hell did you name it great tit? did we run out of bird names or did this guy just like tits a lot?? lol.
