"The purpose of this document is to increase public awareness of the potential impacts of towers and other human-made structures by highlighting some of the pertinent literature on the subject. The bibliography focuses primarily on collisions with communication towers, lighted buildings, and (to a lesser degree) windows. No effort has been made to cover collisions with power lines or wind turbines, topics that have been addressed by Bevanger (1994) and Hebert et al. (1995)"--Introd.
