In a letter about a new nation wide wi-fi deployment (called *FirstNet), the US Department of the Interior states the wireless proposal threatens birds, and is not consistent with current information and laws that protect birds. They called for an environmental review.
Two hundred forty one bird species are at mortality risk from both tower collisions and from exposure to the radiation towers emit. This includes birds that are endangered or threatened, Birds of Conservation Concern, migratory birds, and eagles. They estimate up to 6.8 million bird deaths a year may result from collisions with towers.
Studies of radiation impacts on wild birds documented nest abandonment, plumage deterioration and death. Birds studied included House Sparrows, White Storks, Collared Doves, and other species. Studies in laboratories of chick embryos documented heart attacks and death.
In their letter, The Dept of the Interior criticizes the FCC’s radiation safety guidelines stating,“the electromagnetic radiation standards used by the Federal Communications Commission (FCC) continue to be based on thermal heating, a criterion now nearly 30 years out of date and inapplicable today.”
