Well, they're not pigeons, they're sage grouse, but a federal judge nixed the idea of building a big farm of aerial Cuisinarts in the Steens Mountain area of eastern Oregon over concerns about the birds. Evidently, it's okay to kill a bunch of raptors and thousands of bats with these "green power" monstrosities, but the ground-based sage grouse must not have its habitat disturbed.
Greater sage grouse need sagebrush year-round for mating, nesting and rearing their broods. They also eat pretty much only sagebrush through the winter. Loss of sagebrush habitat has contributed to sage grouse population decline in Oregon.
Environmeddlists are thrilled with the verdict, which is kind of amusing since they push "green energy" right up until it doesn't suit them.
As an aside, we have no wind turbines around here, and it's quite nice - I noticed a bald eagle catching a thermal yesterday just above our house; he showed up right around the top of our pine tree and circled until he gained enough elevation to head over the mountain-top toward the river.
