    Subspecies groups and future splits

    The recent Clements checklists show every sign of being generated from a database. Which is not surprising considering the number of database specialists they must have on staff. The latest checklist did have subspecies Terpsiphone atrocaudata illex belonging to subspecies group Terpsiphone...

    Subspecies groups and future splits

    I found one entry on a BirdLife spreadsheet from a few years ago which had a non-breaking space in the middle of a name. Took me a long time to figure that one out.

    Subspecies groups and future splits

    You're correct; the Birds of the World spreadsheet contains a (presumably complete) list of subspecies. What I see in the book ATBOTW is drawings of a short list of subspecies for each species. However if you look at e.g. Synallaxis rutilans it says "7 sspp in 2 groups" and there are 3 drawings...

    "Barrow's Bustard" seems like it should be in the "Colonial Administrators" group under Denham's. :cool: Unfortunately I don't see any other vernacular name for it in current use; you might be reduced to "Northern" and "Southern White-bellied".

    Subspecies groups and future splits

    However, XenoCanto and Earbirding have considerably better information (it seems to extend to northern Alberta). This range description is pretty much identical to what appeared in the physical book published in 2000 and probably earlier versions too. I know, I know, it's an immense and...

    Subspecies groups and future splits

    "Roughly" indeed. Here's an example from Clements which I happened to be looking up yesterday: Vireo gilvus gilvus. The range description says "SW Canada to e-central US; winters to ne Costa Rica" Living in SW Canada as I do, I was interested to find out whether I was seeing this Warbling...
