Streamers?

It seems like birds flying near a new plant in the Mohave Desert are igniting in mid air.  Via CBS News.

Workers at a state-of-the-art solar plant in the Mojave Desert have a name for birds that fly through the plant's concentrated sun rays - "streamers," for the smoke plume that comes from birds that ignite in midair.

 Federal wildlife investigators who visited the BrightSource Energy plant last year and watched as birds burned and fell, reporting an average of one "streamer" every two minutes, are urging California officials to halt the operator's application to build a still-bigger version.

They're catching fire in mid-flight?  That's kind of tough on the local wildlife population, isn't it?

I don't think hat's what they mean by green energy.
