Crane power strip

Crane species are declining around the world, and lethal collisions with power lines are an ongoing threat to many crane populations. Randomly assigning the ACAS to be on or off each night, they observed the behavior of cranes flying along the river at dusk and during the night. My studies included collisions involving numerous species and families of birds, even on lines modified to industry standards to mitigate avian collisions, and I thought perhaps there could be a more effective approach," says Dwyer. I thought it would have some effect, but I didn't dare think the ACAS would pretty much solve the Sandhill Crane collision problem at our study site on our first try.
