1104. Passer montanus tibetanus

(1104) Passer montanus tibetanus Stuart Baker.
THE TIBETAN TREE-SPARROW.
Passer montanum obscuratus, Fauna B. I., Birds, 2nd ed. vol. iii, p. 179.
Passer montanus tibetanus ibid. vol. viii, p. 656.
In the ‘Fauna' I suppressed my tibetanus, but Meinertzhagen later showed that the Szechuan bird, obscuratus, was larger and that tibetanus must he retained. The range, therefore, of our bird will be restricted to South Tibet and Sikkim.
I have no record of this Sparrow breeding within Indian limits, but it will certainly be found to do so in Sikkim at great elevations. In Tibet it breeds in numbers between 12,000 and 15,000 feet, whilst in Sikkim St. J. Hickley found it in Summer between 10,000 and 12,000 feet. This bird is extremely common in and all around Gyantse, Ludlow (Ibis, 1928, p. 65) writes :—“A resident. Common everywhere from Yatung to Gyantse. In winter they keep to the neighbourhood of houses, but in summer many wander further afield, and often breed at a considerable distance from human habitations. In early autumn they occur in large flocks in the harley-fields, where they do much damage. The breeding season is an extensive one—from April to July. The nest is an untidy structure of grass, wool, feathers, bits of rag and other odds and ends. Sometimes it is placed under the eaves of a house, and sometimes in holes in banks and walls. Clutches vary from three to five.”
A great number of their eggs have been sent me from time to time by various correspondents from Gyantse, and I have records of nests taken in walls and under the eaves of houses, in retaining and boundary walls and banks, and also from holes in trees, though this last seems unusual.
I have eggs taken from the 23rd May to the 7th August, but have been informed that many birds breed in April. The eggs are typical Tree-Sparrows’, but as a series are very brown, some clutches quite richly so.
Fifty egga average 20.8 x 15.1 mm. : maxima 22.0 x 15.3 and 21.0 x 16.9 mm.; minima 19.5 x 13.9 mm.
