Maybe I miss some of the intricacies of what's going on there... Northern Goshawk is changing to American vs Eurasian for birders everywhere but I seriously doubt anyone will bat an eye or do anything other than just keep calling it Goshawk. I do agree with the desires to maintain local names where there are actual differences - ie, keep the differences between Diver/Loon, Tit/Chickadee, Grey vs Black-bellied Plover, Grey vs Red Phalarope, Jaeger vs Skua, etc. Though I wouldn't lose sleep if they all suddenly changed. I've done enough birding in the US vs Europe that I'm quite versed using the wrong name for both audiences regularly. However on the example of "Knot" changing to "Red Knot" on official lists... that's something I wouldn't even notice and if I did I wouldn't blink at it. Of course that's my subjective opinion on the last bit, and I think it's the bit that I least understand being upset over. Surely there are bigger grievances in the world?
