Palaarctic Birds' Eggs from Tibet. 345 



taken near Gyantse on the 10th of May, 1905. These eggs 

 closely resemble those of Archibuteo lagopus, and when 

 placed in a series of the latter cannot be separated. The 

 measurements are 2'38 by 1-82, 2*3 1 by 1-86, and 2-40 by 

 T88 in. respectively, and they vary considerably in markings. 

 (This bird breeds amongst the hills around Gyantse, and 

 the nest was placed on a ledge on the steep side of a deep 

 nullah about thirty feet from the ground and fifteen feet 

 from the top. It was constructed of large sticks and twigs, 

 with a scanty lining of grass. The eggs weighed 2 oz. 

 110 grains, aud the bird is said to occasionally lay four. I 

 shot the adult female, which had the iris greyish brown and 

 the bill and feet brown; in the gizzard was a mouse-hare, 

 of which there were many all round the nest. This species 

 is said to feed also on fish and lizards, but never on carrion 

 or small birds. The male was flying round and seemed to 

 be darker in colour, but I could not get it. Local name 

 Nya-sen, at Lhasa Isib-lak.)

Three eggs, one of which arrived in small pieces, with one 

 of the parent birds, an adult female. They vary con- 

 siderably in markings, aud closely resemble eggs of Milvus 

 cpggptius, but are larger, the two which arrived safely 

 measuring 2'20 by 175 and 2*27 by 1'76 inch respectively. 



(This Kite breeds near Gyantse all through the month of 

 May. I examined several nests, and never found more than 

 a single egg. The bird sent had the iris grey. The food is 

 principally carrion. Local uaraeDe-Ze, at LhsLsaPing-gyii-ma.)

One clutch of three eggs, taken at Gyantse Jong on the 

 22nd of May, 1905, which are blotched and marked with 

 dull red on a yellowish-white ground. 



(The eggs were laid in a hole in a wall, in a little hollow 

 with a rim of clay. I also found young birds on the 2nd of 

 June in a hole in a high clay-bank. The local name is Ira.)
