The park contains fossilized remains within the sedimentary layers that date back to the Miocene epoch.
The distinct multi-colored hills are known locally as 'geological rainbows' due to the varying mineral content in the clay.
It is one of the few places in Central Anatolia where the black stork successfully breeds.
The sanctuary was formally established to protect the ecosystem formed by the sedimentation of the Sarıyar Dam, which was completed in 1956.
The bird population density peaks significantly during the spring and autumn migration cycles.
Davutoglu National Park, officially recognized as the Nallıhan Bird Sanctuary (Nallıhan Kuş Cenneti), is a critical wetland ecosystem situated along the Aladağ River delta. The landscape is dominated by unique multi-colored sedimentary rock formations, specifically red, yellow, and grey siltstone layers created by volcanic activity. It serves as a vital stopover for migratory bird species, including the black stork, grey heron, and various raptors. The park features a designated observation tower that overlooks the confluence of the Aladağ River and the Sarıyar Dam reservoir. The region is known for its high biodiversity, supporting over 180 bird species throughout the year. The terrain consists of arid hills contrasted sharply against the water-logged marshlands of the valley floor.
