color especially on the underparts. Upperparts in fresh pelage dark 
mouse gray with a little light silvery ticking; underparts paler, the 
basal color slate color to blackish slate instead of slate black, the tips 
very pale broccoli brown, much paler than in fumosa; feet averaging 
considerably paler; tail decidedly more distinctly bicolor (in fumosa 
as a rule the tail is practically all dark or at most only very slightly

from Nairobi tend more or less toward the new form but appear to be 
referable to fumosa.
