Manx Shearwaters on Lundy: Further ringing studies and observations on breeding status
Taylor, A.M. (1990) Annual Report of the Lundy Field Society 40:31-33
Abstract
In an earlier paper (Taylor [1986]), information gained from ringing and other observations was shown to indicate that Manx Shearwaters (Puffinus puffinus) attempted to breed on Lundy but were largely unsuccessful. Since then a further 244 Manx Shearwaters have been ringed on the island, forty have been retrapped and three from elsewhere have been controlled. In contrast to earlier work, which had been carried out at a variety of sites, most of this recent ringing effort has been concentrated in a small area. It is a sloping patch of short turf, less than 50m square, just above the cliff top, between the Old Light and the Battery. Compared with surrounding areas there is much less Bracken (Pteridium aquilinum) and fewer exposed boulders, making the observation and catching of birds considerably easier.

Birds have been found to enter burrows regularly in this area and have been detected underground during the day in April, May and July by playing tape-recordings of Manx Shearwater calls outside the burrows, eliciting calls from the birds inside. In previous attempts to find birds later in the breeding season, in late August and early September, the searches had not been focussed on such a well-established site, so at the end of August 1988 the study area was visited to look for any signs of activity.
