Covering nearly 1,500ha this is one of the largest wetlands on Corsica and despite much habitat degradation and disturbance in recent years, it remains one of the island's most important areas for birds.
Parts of the shoreline, particularly in the south, have reedbeds with some good breeding birds and the lake as a whole attracts a wide range of birds on passage and in winter when numbers can exceed 20,000. Biguglia is a shallow brackish lagoon, about 11km long and 2.5km at the widest point. It lies close to the sea on the northeast coast of Corsica and much of the area is a nature reserve and Ramsar Site.
Adjacent habitats include the nearby sea, sandy and shingle beaches and dunes, saltmarsh and riparian woodlands. Much of the surrounding land is covered with vineyards and orchards. More than 120 bird species have been recorded in this area.
Breeding in the reedbeds of Biguglia are Zitting Cisticola, Cetti's Warbler, Reed Warbler and Great Reed Warblers and Moustached Warbler has recently bred. Drier areas around the lake have Corn Bunting and Cirl Bunting, Stonechat and Melodious Warbler.
Marsh Harrier and Northern Hobby nest in the area and often feed over the lake and its shores. Herons such as Grey Heron, Purple Heron, Black-crowned Night Heron and Little Egret visit the lake on passage and small numbers breed. Other migrants include Black Tern and White-winged Terns, Red-footed Falcon and Osprey. Audouin's Gull is a rare but regular passage visitor.
Winter sees the arrival of Black-throated Diver, grebes, various ducks and Eurasian Coot in large numbers. Moustached Warbler occurs in winter and Ferruginous Duck is regular in small numbers. White-headed Duck, formerly regular, has recently been reintroduced.

Access and Facilities
The southern shore of Lake Biguglia is possibly the best area for birds and can be reached by road from Bastia on the N193. Turn left at Rorgo-Revinco onto the D207 and park beside the road after about 4km where the bridge crosses the canal.
Walk the path between the lakeshore and the canal and view the reedbeds and open water.
A wide range of accommodation can be found in the nearby town of Bastia.
