A man thrown from his race bike after colliding with a bush turkey at Currumbin Valley on the Gold Coast this morning is fighting for his life in hospital.

The 45-year-old was riding west along Tomewin Mountain Road about 6:20am when he struck the bird.

Queensland Police Service said the man was "thrown from his bike, coming to rest a considerable distance away".

He was taken to Gold Coast University Hospital in a critical condition.
