94 A CONTRIBUTION TO THE ORNITHOLOGY OF GILGIT. 
18.—Buteo plumipes, Hodgs. (47.) 
This Buzzard is found in small numbers about Gilgit from 
December to the end of March. A female, shot on the 23rd 
February, measured :— Length, 19 inches ; wing, 15°8 ; tail, 9°8 ; 
tarsus, 2°6 ; bare portion of tarsus in front, 1 ; bill from gape, 1:6; 
weight, 1 lb. 15 oz. Iris drab; tail with mottling and traces 
of imperfect barring near the shafts of the feathers only. 
Another female, shot on the 21st March, measured :—Length, 
21 inches ; wing, 16; tail, 9:6 ; tarsus, 2°7 ; bare portion of tarsus 
in front, 1. Iris hair-brown; tail barred. Both these specimens 
are in the phase of plumage to which the title of Buteo 
japonicus is usually applied. 
19.—Circus cyaneus, Lin. (50.) 
The Hen-Harrier is a winter visitor, arriving in the last 
week of September and leaving early in May. Immature 
males, in the plumage of the female, and adults of both sexes, 
have the irides yellow; the immature female has the irides 
hazel-brown. 
20.—Circus macrurus, Gel. (51.) 
This species must, I think, be considered a winter visitor, 
appearing at the end of August, and leaving about the middle 
of May. I have shot it in Gilgit early in January, and 
observed it throughout the winter of 1879-80. Like Czrcus 
cyaneus, in this species the adults of both sexes and the 
immature male have the irides bright yellow, while the 
immature female has the iris dark brown. 
21.—Circus cineraceus, Mont. (52.) 
This Harrier passes through Gilgit on migration, being 
fairly common from the third week in March to the first week 
in May, and re-appearing on its way southwards about the 
third week in September. In two adult males the iris was 
bright yellow; in two immature males the iris was _ hazel, 
slightly tinged with yellow in one, and pale straw-colour in 
the other example. . 
22.—Circus eruginosus, Lin. (54.) 
In twelve specimens, the males have the wings 14 to 16°1 
inches ; the females 15°4 to 17. The adult female has no grey 
colour on the wings or tail. If in this sex the plumage of the 
adult male is ever assumed, the case must be as exceptional 
as in the Kestrel. The adults of both sexes have the iris 
yellow ; and the immature birds of both sexes have the iris 
brown, In the male changing to adult plumage, the tail is
