The south Caspian Sea retreat will remain dominated by its northerly guests until about mid-May 2018 when the migration season comes to an end.
The rich landscape attracts hundreds of birdwatchers, holidaymakers, and bird buffs as well.
In a wider scene, the mid-winter population of the migratory birds is estimated to exceed over a million in the whole southern sandy shorelines of the Caspian Sea that spans some 700km.
The northern provinces of Gilan, Golestan, and Mazandaran embrace a variety of freshwater lakes, wetlands, and lagoons, which are the main destinations for traveling pelicans, flamingos, ducks, swans, coots and some other species.
