Aras

The Aras (also spelled Araks, Arax, Araxes, or Araz) is one of the longest rivers in Azerbaijan. The river is a Caucasus river. It begins in eastern Turkey and travels through the boundaries of Turkey and Armenia, Turkey and the Azerbaijani exclave of Nakhchivan, Iran and both Azerbaijan and Armenia, and eventually through Azerbaijan to the Kura River. It drains the south side of the Lesser Caucasus Mountains, whereas the Kura drains the north side. The river has a total length of 1,072 kilometers (666 miles) and a watershed area of 102,000 square kilometers (39,000 sq mi).

KuzeyDoğa, a Turkish non-governmental organization for environment conservation, created a bird study and teaching center in the Aras Valley at the hamlet Yukarı Çıyrıklı, in the Tuzluca district of Iğdır Province, Turkey, in 2006. It is one of two year-round bird-ringing sites in Turkey. More than 145,000 birds of 201 species were ringed and 306 bird species were sighted at this station between 2006 and 2021. This wetland is home to 63 percent of Turkey's 489 bird species, making it the most species-rich wetland in eastern Turkey.
