Grouville Marsh is the best habitat of its type in Jersey and probably the whole of the Channel Islands. The centre of the marsh is thick with reed beds and not generally accessible. However, many of the best birds which visit, are viewable in the flooded fields around the perimeter.
Many duck species visit, including Wigeon, Shoveler and Teal. Bean, Whitefront, Greylag, Brent and even Egyptian Geese have been seen here in recent years.
Rare birds recorded here have included Bittern, White Stork, Night Heron, Black Kite, Yellow browed and Dusky Warbler. Cetti’s Warblers occasionally breed.
