|This peregrine falcon was found emaciated at BrightSource Energy's Ivanpah solar project and later died. Note the clear singing of the feathers likely caused by the intense heat generated by BrightSource's mirrors.

Shawn Smallwood, an expert on bird mortality at renewable energy projects, submitted testimony that the Palen hybrid project could incur as many as 10,787 birds per year (at an 80% confidence interval) based on preliminary data from Ivanpah and a study of bird mortality at the smaller Solar One in Dagget during the 1980s. Mr. Smallwood also critiques BrightSource's proposal to use various technologies in an attempt to deter birds from coming close to the Palen project, such as the use of lasers, balloons and an untested means of disorienting the magnetic field of birds. As Mr. Smallwood notes, "[a]nother approach with just as much sense would be to cut off one or both wings of birds so that they cannot fly at all." Discussion at the evidentiary hearings this month may also examine whether or not BrightSource can curtail operations of the Palen project during peak bird migration months or when migratory birds are nearby, but BrightSource itself has pointed out that this would be infeasible because financially and because the project takes too long to power down.
