The U.S. Fish and Wildlife Service's Division of  Migratory Bird Management first focused in detail on the growing problem of bird collisions with communication towers due to the attention drawn from a large, single-night kill of between 5,000- 10,000 Lapland Longspurs and other songbird species at 3 towers in western Kansas in 1998. Since then, the Service has developed a communication tower risk model (1998), convened a facilitated meeting of the various stakeholders (1999), cosponsored the first ever workshop on avian mortality at communication towers held at Cornell University (1999), convened and chaired the Communication Tower Working Group (1999) -- designed to determine through research what about towers attracts and not infrequently kills millions of migratory songbirds, sponsored publication of a detailed literature review (2000), helped develop voluntary tower siting guidelines for use by the industry (2000), and updated a mortality estimate for songbirds based on the exponentially growing number of communication towers being built nationwide (2001).
