Abstract
The breeding status and number of Manx Shearwaters on Lundy nave never been
satisfactorily determined. This paper describes the methods and results of a
survey to seek to establish this information. In mid-May 2001 all potential burrows
on the island were checked using tape recordings of the birds calls to ascertain
occupancy. In total 7,000 burrows were checked and from these 154 responses
were obtained from sitting birds. This equates to an estimated breeding
population of 166 pairs, - a disappointingly small total. The distribution of nest
sites and potential reasons for this small population are discussed.
