This is a follow-up to a previous post summarizing the September 2013 issue of Avian Conservation & Ecology that features several articles with the theme of human-related bird mortality in Canada.
A thread on one of the birding groups that I follow was discussing the effect of wind power on birds and one of the contributors pointed to the Barnard on Wind web site (creator: Mike Barnard). More specifically they referenced the article: How significant is bird and bat mortality due to wind turbines? This article, along with its extensive list of references, contains a wealth of information for anyone interested in understanding the effects of wind-power on bird populations. One of the references in Mike’s article is, in fact, the same article on the effects of wind-power that is referenced by the September issue of Avian Conservation &Ecology.
It’s a great and informative site that’s definitely worth a bookmark.

Thanks for the reference Kevin. Please feel free to reach out if questions arise. I’m in contact with ornithologists around the world on this subject and keep up to date on current studies of avian mortality related to wind energy.
You are welcome. I enjoy trying to understand issues where the ‘right’ conclusions may not always be obvious. Your articles are quite informative for the wind-power/birds issue. I am also both fascinated and frustrated by these kinds of issues which polarize into sides that can reach such apparently different ‘scientific’ conclusions looking at the same data. I’ve seen it in many areas (science vs deniers in climate change is one of the ‘best’). I even looked into one of these, real-grass vs artificial turf, in more detail in my other less birdy (and less active) blog (http://ponderterra.wordpress.com/2012/01/02/artificial-turf-grass-lawn-good-idea-or-bad/). It can be a lot of work getting to the ‘truth’.
It’s a challenge. Everyone in the wind industry and major bird preservation organizations agrees that wind turbines kill birds. And they all agree that wind energy is better than the alternative, and that they can do better. They’ve been working together for decades to understand the impacts, improve siting approaches and minimize impacts.
Wind energy avian impacts are much, much more closely assessed and monitored than any other technology of even similar impacts, never mind the much worse impacts of other technologies such as lit windows, power lines and cat claws. It’s not particularly fair, but that’s reality and I’m a big fan of reality.
