This seems to he a North-Eastern form of the Kansu Great Rose-Finch, being extremely common in Ladak and adjoining Tibet, but not occurring in South Tibet, where the birds seem nearer to the typical race from Kansu.
The first nests and eggs of this bird were taken by Major Corbett and sent home to Dresser with two birds, and Dresser (Ibis, 1904, p. 109) points out that the birds are intermediate in colour between true rubicilla and severtzovi.
We have an excellent account of this bird by Osmaston (Ibis, 1925, pp. 690-692), which I quote in full:—“This species is common throughout Southern and Eastern Ladakh between 12,500 and 15,500 feet wherever Tama bushes or any other shrubs occur,
“They were first observed in the Tama scrub near the Tso Moriri Lake at about 15,000 feet on the 10th June, and during the next ten days or so they were seen building at every camp.
“The song of this bird is very poor. It consists of two notes only, the first being higher in the scale.
“This species is not found near Leh, nor, indeed, was it seen anywhere North of Leh.
“Large shrubs or even willow-trees are preferred as nesting sites, and nests were found up to 15 feet from the ground. As, however, trees and large shrubs are, as a rule, scarce, while the Tibetan furze is exceedingly common, the majority of nests are in furze-bushes.
“In the Puga Valley, at an elevation of from 13,500 to 14,000 feet, many old nests of this species were found in which dead hen birds were sitting. These dead birds did not all belong to this species. There were also dead Twites and Hedge-Sparrows. The birds had evidently died the previous summer but, owing to the dryness of the climate, they had not decomposed, but had simply dried up ! The cause of death was not apparent, but it may possibly have been due to cold—an untimely blizzard, similar to one experienced by me on 12 July, would, perhaps account for it.
“In the first ten days of July many nests were found, mostly containing fresh eggs. They were rather massive structures made of small sticks and twigs, followed by a layer of dry grass, and lastly a lining of wool and hair. Five eggs are generally laid, but four or even three incubated eggs may be found. The hen bird sits very close, and will almost allow herself to be caught on the nest.
“Eggs are a rather deep blue, marked rather sparingly with a few large black spots.
“The following is a statement of nests found :—
“June 19. Tso Moriri, 15,000 feet. Building.
“June 24. Puga, 14,500 feet. Several pairs building.
“June 26. Below Puga, 13,500 feet. Many pairs building.
“June27. Nimu, 14,000 feet. Building.
“June 30. Raima, 14,000 feet. Building.
“July 1. Tsakjung, 14,800 feet. Many pairs building. First egg found.
“July 2-6. Shushal, 14,200 feet. Seven nests with eggs (two to five fresh eggs in each nest).
“July 7. Takkung, 13,900 feet. Many building, six with eggs.
“July 8. Merak (Pangong Lake, 13,900 feet. Five nests with eggs.
“July 9. Man (Pangong Lake), 14,000 feet. Three nests with eggs.
“From July 10 our course was mainly at lower levels, and this species was only occasionally seen. The eggs taken varied in length from 27.2 to 22.2 and in breadth from 19.0 to 16.2, the average of ninety eggs being 24.1 x 17.6.” 14,000-15,000 feet, all built in Caragana scrub. He obtained many clutches of eggs between the 5th and 8th July.
Thirty-four eggs measured by myself average 23.7 x 17.1 mm. : maxima 25.7 x 18.0 mm. ; minima 22.0 x 16.0 and 25.0 x 15.9 mm.
