    Was rufula originally described (Temminck 1835) as a separate species or as a subspecies of C. daurica? If described as a separate species, anyone know when and where it was lumped as a subspecies of C. daurica? I notice there are several Asian (and African) ssp. of both C. daurica and C...

    These locations corresponds to the distribution of C. d. rufula. C. d. daurica and C. d. japonica (+ maybe other Asian subspecies?) are morphologically closer to C. striolata than to C. d. rufula.

    I guess the "Begin long overdue revisions..." indicates that more changes may follow, but so far the only Muscicapidae updates posted on the Taxonomic Updates-section concern (mainly/only) Afrotropical species. Taxonomic Updates – IOC World Bird List

    Will IOC consider all the conclusions in Sangster et al, or just the split of Red Grouse from Willow Grouse? From a Norwegian perspective the discussion on ssp. variegata is of great interest as it is the only endemic taxon in Norway. From the paper: "The combined morphological, allozyme and...
