Feeding ecology of Common Guillemots on Lundy: productivity in 2014

2013 - Productivity on Lundy - 2015
Summary

In 2014 there were 16 focal sites on my St Philip's Stone survey ledge. Site H was unoccupied this year, perhaps due to the severe storms of winter 2013-14. There were 15 active sites and one regular site. 12 sites produced chicks that either fledged, or were of fledging age (+15days old) when last seen. This gives a productivity of 75%
