Hurricane Birds – the aftermath of Irene


Some years ago when I was a budding birder living near the Atlantic Coast, I learned of one of the craziest aspects of hard core birding: hurricane birding. Much like the surfers who get excited by impending storms, we birders … Continue reading

Vertical Axis Wind Turbines


Phil Berardelli (ScienceNOW Daily News) has published a neat story here on the benefits of a specific configuration of vertical-axis wind turbines (VAWTs; example here). VAWTS, arranged in a pattern that mimics schooling fish, can provide a similar energy output … Continue reading

The dark side of wind power


We can talk about numbers – more birds are killed by windows than anything else – so the number of birds killed by wind turbines is generally thought to be an acceptable amount of “collateral damage.” But what about seeing … Continue reading

Turbines’ pressure drop too much for bats


It’s not just an awesome reggae track from Toots and the Maytals – “pressure drop” is also a fairly serious problem for bats around wind turbines, a new study suggests. Writing in the journal Current Biology, Erin Baerwald and colleagues … Continue reading
