Manx Shearwater breeding success on Lundy 2007

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.
