Campaigners have made a last ditch attempt to stop work on a multi-billion pound high-speed rail link - cutting through the Buckinghamshire and Oxfordshire countryside.
Protestors say 500 acres of precious land is being cleared during the bird nesting season - to make way for HS2. The company responsible for the work says it will be one of the most environmentally responsible infastructure projects.
The £56 billion rail link would run from London Euston to the Midlands - and then onto Leeds and Manchester. The first phase isn't due to open until 2026.
Opponents travelled to Birmingham to hand in a petition with thousands of signatures. There for us was our Transport Correspondent Mike Pearse.
