Zoology
The lacustrine avifauna of Ulster is important, as the large lakes, such as Lough Erne and Lough Neagh, have an abundant bird population. Among the breeding species arc the Tufted Duck, (now widespread), Shoveller, (increasing) ; Common Scoter, (recently found breeding on Lough Erne) ; Red-breasted Merganser (frequent; also on marine islands) ; several species of Gulls and Terns; Oyster-catcher (breeding on Lough Neagh) ; Great Crested Grebe, (frequent) ; and Red-throated Diver (one breeding station).
