Counting corncrakes on Orkney night shifts
Newly sober after rehab and years of heavy drinking in London, Amy Liptrot took a job with the RSPB surveying corncrakes in Orkney. In the early hours she drove island roads, stopping to listen for the rasping 'crex crex' of calling males and logging each one. Mechanised mowing had driven the species close to extinction there, so the survey came down to a few birds counted night after night.
