Hazards related to man-made structures: Buildings, noise, electric power

Many man-made structures can form a hazard to avian wildlife. The most common hazard is one of collision, and this paper will look at problems with glass in buildings, power lines, and wind turbines all as sources of collision and trauma to avian wildlife. However, other anthropogenic factors that can adversely affect avian wildlife can be those that effectively eliminate suitable habitat for avian wildlife. These can include noise factors associated with such things as wind turbines and construction areas and the loss of habitat to large solar arrays, not to mention strip mining for coal and oil-sands. All these factors can contribute to the estimated loss of 3 billion birds in the last five decades.
