The SACC (and presumably the NACC) have taken the view that future new bird names should avoid the use of eponyms. As this was a very recent split, both committees seem to be revising the names.Two more eponyms to bite the dust, I haven't looked in to the reason ........
Jan 31 Change English names of Catharus dryas and C. maculatus.
Gould's (I presume the Shortwing and Gouldian Finch will meet the same fate?) and Sclater's Nightingale Thrushes.
And why are they changing the Diuca Finches? A brief search yielded the fact that Diuca is originally a rural Chilean term for penis?
I dont think there is any suggestion (yet) to specifically target Gould or Sclater themselves.
The Diuca Finch situation was simply because White-winged and Common were recently found to be unrelated at roughly the same time that White-winged's unique nesting behaviours came to light. Glacier Finch is a much better name for White-winged.
