Manx Shearwater breeding success on Lundy 2007

Booker H, Price D & Taylor AM (2008) J Lundy Field Society 1:47-56

Surveys over the past 30 years have shown that Lundy has a small population of Manx Shearwaters (Puffinus puffinus). Until recently, autumn searches failed to find evidence of successful breeding. The principle reason was considered to be predation by rats. A major conservation project, which removed rats from the island, was completed in 2004. Observations of juveniles in 2004, 2005, and 2006 proved successful breeding and led to a more detailed study in 2007. In this study, young birds emerging from burrows prior to fledging were captured and ringed. Using mark-recapture analysis, a productivity estimate has been made.
