During the same time as he was becoming more educated about bird - protection, the office experienced
several bird collisions against the window.
As wind turbine technology catches up with the latest solar cell inventions, other research
on bird collision risk and marine mammal injury mitigation will complete preparations for larger scale wind - energy projects, just as recent research is also providing evidence of varying bird risks occurring at different heights (and for different species.)
Estimates
of bird collision mortality at wind facilities in the contiguous United States Loss, Scott; Will, Tom; and Marra, Peter
According to the volunteer group
Chicago Bird Collision Monitors, dead birds were found at the Apple Store site, due to their propensity for becoming disoriented due to the store's lights, before crashing into the glass walls.
She writes about Chicago's new LEED Platinum FBI Headquarters, which brought in Annette Prince of the Chicago
Bird Collision Monitors to help reduce bird deaths at the building.
«For one thing, every point of view has its own science and economics to support its contentions, whether it be pro- or anti- pesticide use, free - roaming cats,
bird collisions with glass or towers, conflicts with fisheries, land conversion, wind energy, mining, timbering, climate change, or any other issue we consider in addressing bird conservation...» [2]
Getting architects to think about bird - friendly design can be difficult, said Christine Sheppard,
bird collisions campaign manager for the American Bird Conservancy.
Bird collisions have been one of the primary negatives of the recent growth in wind power across the United States and beyond.
That said, the researcher concludes that «strictly enforcing speed limits could reduce
bird collisions.»
Magpies accounted for 43 % of
all bird collisions.
Bird collision on wind turbines have been reported in many journals and papers; we have not yet found any birds hit.
With modern turbines, mounted on tubular towers and whose blades spin only about 15 times per minute,
bird collisions are now rare.
