(1275) Aethopyga nipalensis horsfieldi.
Blyth's yellow-backed sunbird.
Cinnyris horsfieldi Blyth, J.A. S.B., xi, p. 107 (1842) (Descr. nulla) ; id. ibid., xii, p. 975 (1844) (Himalayas, restricted to Mussoorie). Aethopyga horsfieldi. Blanf. & Oates, ii, p. 356.
Vernacular names. None recorded.
Description. - Male. Similar to the preceding bird but with very little crimson showing on the back except as a narrow collar next the neck; the lower parts are paler and have very little or no scarlet streaking on the breast.
Colours of soft parts as in the other races.
Measurements. The same as the preceding bird but with culmen 17 to 19 mm. though nearly always 18 mm. or under.
Female. Not distinguishable from the other races, unless by the shorter bill.
Distribution. Garhwal and Kuman. There are no specimens from Nepal and it is unlikely to occur in that State unless in the extreme West near Garhwal. Mr. Frith who sent the original specimens described by Blyth merely said they were from the hills (=Himalayas).
Habits. This Sunbird resembles the typical form but very little has been recorded about its Habits. It occurs between 2,000 and 6,000 feet and possibly a good deal higher than this.
