Bird's opening.
what is the name of the opening movement begins with f4?

Generally it is a fight for the e5 square and a kingside attack

I thought it meant it was like flipping the bird.
Named after Henry Bird

Bird opening is a very unstable opening. There are many ways where black can overtake/demolish white for making such an unsound move. Unless you're willing to be bashed with tons of counterplay from black. Don't play it.

The bird's opening is = nothing more, nothing less, its like the english opening, but white has less active play, and tbh, white has more weaknesses in general. This from about a year and a half of experience playing the opening.
Imo, if you want to play to play some random opening for white, the best option is really 1.b3

Not so bad.
But one of the mainlines of the Bird is the From gambit (1.f4 e5), and that fact should make you suspicious. If Black gambits a pawn at move one and is considered to have enough compensation, there must be ways to go very wrong, very fast.

Gah he beat me to the music reference!
Anyway there are numerous approaches to the Bird like other openings so you are spoilt for choice. The most common after 1.f4 d5 is a setup with Nf3, Bb2, Bb5/Bd3 aiming for a kingside attack.
There's also a Leningrad Bird where White plays Nf3, d3 and prepares to slowly play e4 to control the center.
There's another one (I don't know the name) where White tries to play e4 without developing other pieces after 1.f4 d5 2.Nf3 Nf6 2.d3 e6 3.c3 c5 4.Qc2 and White just plays e4 next turn.
All this stuff is supposed to be equal but you can get good games with them.

The opening movement that begins with f4 I think is Beethoven's 5'th symphony.
No, it begins with g4.

Have you seen that video of Jerry's where he plays someone with an offensive avatar (you can guess) and then plays the bird opening...hilarious. :D

Transpose it into B flat minor! (that wouldn't work, because the cellos would have to play a low Bb in the 2nd movement, which would now be in G flat major.)
