Seabirds nest in places that are inaccessible for most humans - vertical cliffs and remote islands surrounded by raging waves. Worse still, many seabirds lay their eggs in burrows or cavities where they are protected from inclement weather and invisible for researchers. Hidden under rocks or in burrows during the day, and flying around only during dark nights - counting these birds is a researcher's nightmare.
