The Orient Forest Regional Nature Park is a site of major ornithological interest. Its aquatic and terrestrial habitats are diverse, and their location on the avifauna's migratory routes is advantageous. The proximity of the oak forest makes Orient Lake, which extends inside the park, particularly attractive for birds. They feed on the acorns there while resting on the lake's reed beds. The aquatic vegetation is dense and quiet enough to encourage the birds' reproduction. The large mudflats, which emerge in the fall, provide them with additional food.
