Grassholm
Olympus OM4, Ektachrome EB100, digitised by photographing the original 35mm slide on a light table using a 12mm extension tube; tethered capture and digital processing in Lightroom. The Northern gannet ( Morus bassanus ) is nearly a metre long with a wingspan of around 1,75m and a mass of around 3kg; it is the biggest seabird native to Europe. "Grassholm (Welsh: Gwales or Ynys Gwales) is a small uninhabited island situated 13 kilometres off the southwestern Pembrokeshire coast in Wales, lying west of Skomer. It is the westernmost point in Wales other than the isolated rocks on which the Smalls Lighthouse stands. Grassholm is known for its huge colony of northern gannets; the island has been owned since 1947 by the Royal Society for the Protection of Birds, and is one of its oldest reserves. Grassholm National Nature Reserve is the third most important site for gannets in the world, after two sites in Scotland: St Kilda and Bass Rock. It serves as a breeding site for 39,000 pairs of the birds, and supports around 10 percent of the world population. The turbulent sea around Grassholm is a good feeding area for porpoises and bottlenose dolphins."
