[Tweeters] Northwestern Crow back on the docket

[Robert O'Brien]

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.
