Europe, France


This huge bay lies on the northern coast of France where Brittany meets Normandy and forms one of the most important wader haunts in the country.

The major habitat is the very extensive mudflats but there are also saltmarsh areas and islands, coastal grasslands and reedbeds as well as stretches of cliff and rocky shoreline. The western part of the bay has dykes enclosing polders.

The bay attracts in excess of 20,000 birds on passage and in winter including waders as well as seaduck and others and the area receives large numbers of passerine migrants. However, there is also much of interest during the breeding season.


Notable Species

All the regular north European waders can be seen in the bay on passage and in winter but particularly numerous are Turnstone, Oystercatcher, Ringed Plover and Grey Plover, Dunlin, Red Knot, godwits and Eurasian Curlew. Golden Plover, Northern Lapwing and Ruff winter on the nearby grasslands.

Waterfowl present in winter include small numbers of grey geese, thousands of Dark-bellied and a few Pale-bellied Brents, Common Shelduck, Eurasian Wigeon and Common Teal. Barnacle Goose is an occasional visitor with the Brents in severe winters.

This site is of major importance for passage and wintering Common Scoter with as many as 20,000 present at times. Hirundines, pipits and wagtails, larks and buntings are among the many passerines that move through this area in spring and autumn.

Breeding species include Common Shelduck and Mallard, Kentish Plover and Little Ringed Plover and small numbers of Common Quail and Marsh Harrier. Eurasian Skylark, Meadow Pipit and Blue-headed Wagtail breed in good numbers on the grasslands and the reedbeds have Reed Warbler and Sedge Warbler and Reed Bunting.

The cliffs at Carolles on the north-eastern edge of the bay have breeding Shag, Northern Raven and Black Redstart and Lesser Whitethroat, Dartford Warbler and Melodious Warbler nest in the clifftop heath. These cliffs are excellent for watching migration, particularly of passerines, and a wide range of species is possible. Balearic Shearwater can also be seen in good numbers off this point.

Lapland Bunting is regular on the western shores shores of the bay in winter and Short-eared Owl, Hen Harrier, Merlin and Peregrine Falcon hunt over the area in winter.


Greater Sand Plover was recorded here in the autumn of 2002 and again in March 2003.
