Feeding Ecology of Common Guillemot Chicks on Lundy
Birkhead TR, Goodburn SF & Hatchwell BJ (1986) Ann Rep Lundy Field Society 36:25-26
Following a long period of decline, several guillemot Uria aalge populations in the
south Irish Sea have recently shown an upward trend in numbers. At present the
reason for this change in fortunes is not known, but one possibility is that a
change in the marine environment has made food more available to guillemots.
As part of an attempt to examine this, we have compared several aspects of the
guillemot's feeding ecology at three Irish Sea colonies during the chick rearing
period. Information has been collected from Skomer Island, Dyfed, Great Saltee,
Co. Wexford and from Lundy. Here we present the results from Lundy made
between 17th-28th June 1985 about 100m south of St Mark's Stone on the west
coast of the island. All observations were made between 1400-1800h BST.
