The Bird Area (Domaine des Oiseaux) is a 45-hectare protected wetland located near the Hers river in Mazères, France. It serves as a major stopover point for migratory birds traveling along the Pyrenees corridor. The site features multiple ponds, lagoons, and wooded areas designed to mimic diverse natural habitats. An on-site museum preserves rural history through a collection of agricultural tools and artifacts documenting the life of past local communities. Visitors can utilize a network of walking paths and elevated observatories to watch bird species without causing disturbance. The site operates under an ecological management plan that prioritizes the conservation of rare fauna. It functions as both a scientific monitoring station and a public educational resource.
