Fowlsheugh is a coastal nature reserve in Kincardineshire, northeast Scotland, known for its 70-metre-high (230 ft) cliff formations and habitat supporting prolific seabird nesting colonies.
Designated as a Site of Special Scientific Interest (SSSI) by Scottish Natural Heritage, the property is owned by the Royal Society for the Protection of Birds.
Tens of thousands of pelagic birds return to the site every spring to breed, after wintering at sea or in more southern climates, principal species being puffins, razorbills, kittiwakes, fulmars and guillemots.
Due to global warming, the planktonic species previously present that prefer cold water are not available in the quantity required to support the historically large sandeel population.
In places the fissured red-and-green-coloured sandstone is replaced by picturesque conglomerate with roundish stones varying in diameter from two to thirty centimetres (historically known as puddingstone in this region of Kincardineshire).
These lower lying rocky outcrops are an integral part of the Fowlsheugh Preserve, hosting seabird nests as well as a few harbour seals on Craiglethy, who can be seen hauling out or sunbathing on summer afternoons.
As a glimpse into Fowlsheugh in early Victorian times, James Anderson wrote: "a remarkable rock of the conglomerate or plum pudding species called Fowls Heugh, about a mile long and two hundred feet high, quite perpendicular and in some places overhanging, often visited by sportsmen on account of innumerable sea fowl, of the kittiwake species, which resort to it in the breeding season; finding convenient places for depositing their eggs in the recesses formed by the vacant beds of pebbles"[5] It is documented that in the 19th century not only did hunters journey to Fowlsheugh to shoot seabirds, but rock climbers would rappel down the steep cliffs in search of the prized seabird eggs, much in the manner described of Saint Kilda.
As of 2005 about 18,000 breeding pairs of kittiwakes (Rissa tridactyla) return to Fowlsheugh each year, making their nests on some of the most vertical parts of the landscape from muck, seaweed and local grasses.
Smaller numbers of other seabirds nest at Fowlsheugh, including Atlantic puffin (Fratercula Arctica), razorbill (Alca torda), herring gull (Larus argentatus), and fulmar (Fulmarus glacialis).
Marine algae occurring immediately offshore at the Fowlsheugh Nature Reserve include Dudresnaya verticillata, Sauvageaugloia griffithsiana, and Streblonema infestans.
By boat, out of Stonehaven Harbour, there are regular small craft trips available for a moderate charge during the months of May to July, which reach the cliff bases of Fowlsheugh and even traverse some of the marine waterway caves.
