The boys were arranged into four patrols, designated as the Wolves, Ravens, Bulls and Curlews. Wading birds such as snipes, curlews and golden plover feed in the waterlogged bogland. Large groups of lapwings, oyster catchers and curlews can often be seen. Shorebirds such as phalaropes and curlews can be found in wet areas. Among birds klik are rarely seen and stone curlews and jacks very rarely. The surrounding dry prairie uplands offer opportunities to observe marbled godwits and long-billed curlews. Long-billed curlews often feed in flocks. The upland sandpiper ("Bartramia longicauda") is a large sandpiper, closely related to the curlews. Other birds that eat sand crabs include willets, godwits, surf scoters, blackbellied plovers, and curlews. In the Pairc area, one can see feeding oyster catchers and curlews. Eskimo curlews picked up food by sight, as well as feeding by probing. Oystercatchers, redshanks and curlews are common and, in summer, there are flocks of sandwich terns.
