The prevailing shade above and below pale rufous. Terminal two-thirds of the tail-feathers (except the four central) rufous white; outer webs of all mottled, however, nearly to the tips.

The extent of the white spaces on the inner webs of tail-feathers varies with the individual, but in none does it occupy less than the terminal half.
