The Tigris-Euphrates marshlands serve as a critical habitat for a wide variety of migratory birds and seasonal visitors. These wetlands, characterized by their dense growth of reeds, sedges, and other aquatic vegetation, provide essential resources that support these avian populations.1

While the marshes have historically been a vital stopover and breeding ground, it is important to note that large-scale drainage projects in the southern wetlands have significantly impacted these ecosystems. The full extent of the damage to migratory patterns and the populations of seasonal visitors remains a subject of ongoing study, as these birds rely on the unique environmental conditions of the river system to survive their long-distance journeys.1
