2018 eBird Taxonomy Update

    SUBSPECIES RESHUFFLES
    When subspecies move around between species, this can have effects like splits or lumps.
    Thus, for a certain population within a species, the movement of the subspecies from one
    to another has important data quality implications and can significantly change the range
    of both species.

    Grey-headed Swamphen and Black-backed Swamphen: Subspecies vididis, previously
    classified under Black-backed Swamphen Porphyrio indicus, properly belongs with
    Grey-headed Swamphen Porphyrio poliocephalus. This results in a major change in the
    range of the two taxa, since viridis occupied an extensive range in Southeast Asia,
    including Malaysia, s. Myanmar, s. Thailand, Cambodia, Vietnam, Laos and southeastern
    China. Now, that range is occupied by Grey-headed Swamphen, and Black-backed
    Swamphen is restricted to Sumatra, Java, Bali, Borneo and Sulawesi.
