Abstract
The productivity of Black-legged Kittiwake (Rissa tridactyla), Common Guillemot (Uria aalge), and Northern Fulmar (Fulmaris glacialis) was surveyed at four sites on Lundy in 2007. Average kitttiwake productivity was 0.3 per pair, average guillemot productivity 0.27, and average fulmar productivity 0.54 but there were some differences between each study site. There was little evidence of food shortages, but high predation was seen at one site and weather conditions were poor throughout the season.
