As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Can sound protect eagles from wind turbine collisions?

MAY 15, 2019
Every year, bald and golden eagles are killed when they inadvertently fly into wind turbine blades. One possible way to prevent these deaths is to chase the birds away with acoustic signals—sound. To determine what types of sounds are most effective in deterring the birds, researchers at the University of Minnesota and their colleagues tested the behavioral responses of bald eagles to a battery of both natural and synthetic acoustic stimuli.
Auditory neuroscientist JoAnn McGee will present the results of those tests at the 177th Meeting of the Acoustical Society of America, which takes place from May 13-17, at the Galt House in Louisville, Kentucky.
Three adult bald eagles were used for the study: two birds that are unable to survive in the wild and live permanently at the university's Raptor Center, where the testing was done, and one bird undergoing rehabilitation at the center prior to release back into the wild.
Each bird was tested within a 9- by 7-foot space lined with sound-damping materials. The bird was perched on a bar in the center of the room, with loudspeakers mounted on the wall to its right and left; a high-resolution video camera mounted directly in front of the bird captured its reaction to the sounds.
