Tweet of the Week - Tim Birkhead

Professor Tim Birkhead of Sheffield University presents five stories of seabirds from his time spent leading a study of the guillemot population on the island of Skomer for more than 40 years.

Guillemots crowd the cliff-sides in dense populations, which offers some protection from predators but it can stay be a dangerous place to rear young. Tim tells the story of the guillemot chicks attacked by greater black backed gulls, he also describes the ferocious ravorbill, remembers an intelligent ambush by ravens, the dull social lives of puffins and ends with a story that shows the incredible eyesight and recognition of the guillemot.

This week's stories are introduced by natural history radio maker Andrew Dawes.
