Subject: Re: [Tweeters] Northwestern Crow back on the docket
Well it's my understanding that one ornithologist is recommending
reinstatement, with considerable backup data. But there is a rigorous
argument against reinstatement by the ornithologist who got it lumped in
the first place. Not considered as yet so no decision. I would guess,
after reading the arguments, that it will not be resplit.
