Migratory birds leave wetlands of northern Iran
Tehran, April 8, IRNA – A flock of 135,000 migratory birds that had come to the wetlands in Gilan Province in the north part of Iran have flown to their preceding habitats.
It was autumn when the migratory birds became guests of the wetlands, an official in Gilan's Department of Environment Mansour Sarbazi said.
He underlined that the migration of birds from cold regions of Siberia as well as Eastern and Western Europe begins at the end of September as the weather cools and food resources are limited.
The birds stay in the province's wetlands until May depending on the temperature, he further noted.
