Somewhat technical but a must read for anyone contemplating a visit to Idaho to look for this species if it indeed is one. Paul Desjardins Windsor Locks

I know that a new species of "Red" Crossbill was named out in Idaho I believe but I don't remember which it is.  It's been officially accepted by The AOS/ABA I believe and is accepted on the Clements checklist.

I just read the article on the South Hills Crossbill (link provided by Arthur Shippee) that disputes the elevation of that taxxon to species status. It's heavy but fascinating going and I would recommend anyone with a serious interest in bird species give it a go. If you've never delved into the concept of species (beyond bemoaning another change to your life list) it's well worth the effort.

I had a wonderful talk with Matt Young, one of North America’s crossbill experts, about this paper last week. To summarize the conversation we had in the simplest of terms, the position of the author would also suggest that he would be in support of an overall lumping of the Anas and Larus genera as well. I brought up that by the authors definition, Scottish and Parrot crossbills would also have to be lumped. Speciation is an absolutely fascinating concept and one I delve into on a continual basis. The bottom line is there’s no universal definition, which makes it all the more interesting! -Matt Bell Vernon > On Aug 9, 2020, at 19:02, Gregory Hanisek via CTBirds <ctbirds@lists.ctbirding.org> wrote: > > I just read the article on the South Hills Crossbill (link provided by > Arthur Shippee) that disputes the elevation of that taxxon to species > status.
