I suggest you try  the Hobbs and Hobbs-Zilbermints Gambits to defeat the Bird.   Here is how:

HOBBS GAMBIT:  1 f4 g5  2 fxg5  h6 3 g6!

HOBBS-ZILBERMINTS GAMBIT:  1 f4 h6!  2 Nf3 g5  3 fxg5  hxg5  Now if  4 Nxg5  d5! with the idea of ...Qd6, pressuring the weak h2-square. 

I defeated many players with the Hobbs-Zilbermints on the Internet Chess Club.  As for regular over the board chess games, my score is 4/4 .

  Keep in  touch.

Well then I guess 7. 0-0 nbd7 8. c4 c5 it is then. Thanks for the advice  

The main point for black is to not allow 4.b4, since the dual q-side space gain/fianchetto can offer white chances for an advantage. To this end, black should play either 2...g6, or 3...c5 before his kingside fianchetto. The lines with b3, as Tim Taylor shows in his book, do not offer white any chance for an advantage, so the thematic point is to stop the b4 thrust and then look to clamp down later with d4, to kill the b2 bishop.

Still, below master level, such positional nuances aren't quite so important.
