La Pointe de Grave

The Pointe de Grave is the extreme north of the Médoc, between Bordeaux and the Atlantic Ocean. It is located at the mouth of the Gironde Estuary, opposite the town of Royan.
This geographical configuration, unique in France, makes it of great ornithological interest during pre-marital migration: the "funnel" effect concentrates the birds that migrate along the coast and those that, further inland, are reluctant to cross the estuary and follow the bank to its end. These two flows then converge above the Pointe de Grave before crossing the estuary in the direction of the Charente-Maritime and, beyond, towards Northern Europe and Siberia
LPO Aquitaine coordinates the scientific monitoring of the migration, carried out every year from March to May. More than a hundred species are observed during the three months of monitoring.
