Coloration. Adult. Crown brown, the feathers with broad rufous margins, still broader and mixed with buff on the nape; cheek-stripe black, ill-defined; lores and forehead whitish. Upper plumage and tail brown, with rufous cross-bars throughout (somewhat as in a female Kestrel); inner webs of primaries mostly covered by confluent white bars, except near the tips of the feathers; lower parts buff or white, with spots on the breast, abdomen, and flanks, those on the breast and middle of the abdomen disappearing in old birds.
In young birds the rufous bars are irregular and ill-marked, and those on the tail more or less imperfect. In this stage F. milvipes is very like F. cherrug, but may generally be distinguished by some of the bars going quite across the tail-feathers. A nestling from Tibet in the Hume collection, attributed to this species, has, however, the tail absolutely unbarred.
Bill bluish, black at the tip; cere, legs, and feet yellow.
Length of female about 23; tail 9 ; wing 16; tarsus 2.2 ; mid-toe without claw 2 ; bill from gape 1.35 : length of male 20; tail 7 1/2 ; wing 14.
Distribution. Tibet and part of Mongolia. A few birds have been obtained in the Punjab at times, and one by Sir O. St. John at Quetta.
