The Isle of Man is home to many bird and insect species. Many species live in "curraghs" (wetlands in the northeast of the island). Curraghs are protected by the Government of the Isle of Man. Curraghs Wildlife Park is in these wetlands, it is both a zoo and a protected area. During the winter, curraghs are the second largest nesting ground of the Hen Herrier in Europe. The Peregrine Falcon, Merlin, European Robin, Willow Warbler, Song Thrush, Dunnock, Swan and a subspecies of Winter Wren possibly native to the island also nest in the curraghs. The Chough is also in the Isle of Man, it is more common than in other parts of Europe. Some farming methods have decreased the bird population of the island. The Northern Lapwing is now rarely found, and the Yellowhammer is now extinct on the island.
