Thanks so much for this link. A most interesting video! And it almost feels like I know Killian a little bit now. Great talk and impressive person, indeed.Killian Mullarney in a talk a few months back showed off some of Ian Lewington's plates, including longspurs, flickers, Mississippi Kite, and prairie-chickens. They really do look beautiful. I recommend the whole talk for Killian's perspective on the philosophy of field guides.
