Wide of bird selling stores in Moulavi neighbourhood in downtown Tehran\u003cbr/\u003ePollution in the Iranian capital, Tehran, is having a devastating effect on the city's bird life. \u003cbr/\u003eAccording to the Iranian Ministry of Agriculture more than fifty percent of the different species normally seen in the area have migrated because of pollutants and unregulated building work that's destroying their natural habitats.\u003cbr/\u003ePigeons in flight above Tehran. \u003cbr/\u003eThe pigeon is one of the species indigenous to the city along with sparrows, crows, doves, nightingales and jays.\u003cbr/\u003eBut they're fleeing the area because of Tehran's notoriously bad air pollution, according to the Iranian Ministry of Agriculture.  \u003cbr/\u003eAlthough official figures for individual birds are unobtainable, the Department for Birds and Bees Affairs (within the Department of Agriculture) estimates that more than half of bird species common to the city have fled their nests over the last 20 years. \u003cbr/\u003eThe bird's disappearance is worrying for the city's residents and conservationists alike. \u003cbr/\u003e\"The birds have fled away, you know there used to be different types of birds such as doves, pigeons, crows, jays and sparrows. You do not see them anymore,\" says Tehran resident, Aghdas. \u003cbr/\u003eHere a lone crow sits in the branches of a tree.\u003cbr/\u003eThe crow is not a good sign in Iranian culture. It symbolises bad news and gossip. \u003cbr/\u003eStreets void of wildlife, especially birds, can psychologically and indirectly affect the locals' moods.\u003cbr/\u003eThis elderly resident sings a lament - it's an old song about how deeply are people engaged with their day-to-day lives and have forgotten about their environment \u003cbr/\u003eBird expert Amir Mohammad Amir Raad has been studying birds as a hobby since he was a child.  \u003cbr/\u003e\"In big cities because of the lack of safety created by the enormous construction sites, noise pollution , fuel and transport pollution and other type of pollutions such electromagnetic pollutions, birds have started migrating away,\" he says.  \"If you remember the number of birds flying in your neighbourhood in the past and compare

the migration of birds,\" says city resident, Vahid \u003cbr/\u003eHossein Damavandi Nejad, the chief of Department for Birds and Bees Affairs recently warned that mobile phones and other electronic and electromagnetic devices can seriously disrupt the natural wildlife.\u003cbr/\u003eA recent report by Tehran's Controlling Air Quality Company estimates that cars and motorcycles in the city emit 4,400 tons of pollutants each day.\u003cbr/\u003eTehran's city council says that equates to 80% of poisonous gases measured in the city.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv
