THE BLACK-THROATED JAY.
Garrulus lanceolatus, Fauna B. I., Birds, 2nd ed. vol. i, p. 60.
The Black-throated Jay breeds during April, May and June from Chitral and Hazara to Nepal, including practically the whole of Kashmir proper, the Simla States and Garhwal, at all elevations from. 4,000 to nearly 9,000 feet. It is extremely common round many hill-stations such, as Murree, Mussoorie, Simla and Naini Tal, where they are most numerous between 5,000 and 7,000 feet.
Occasionally this Jay breeds actually inside forest but, as a rule, they select, some small tree or sapling standing either alone or with others in comparatively open, land, often in cultivated tracts. The favourite tree for building purposes, wherever this is found, seems to be the Oak, Quercus incanus, and, for choice, a small one in which the nest can. be placed somewhere near the top, anything between 15 and 20 feet from the ground. They never seem to build in any of the evergreen coniferous trees, even where these form the majority growing, though all other kinds of trees are made use of, whilst Osmaston took a nest at Chakrata from a Rhodo¬dendron about 8 feet from the ground. No attempt appears to be made to conceal the nest and, often, when placed in a lightly foliaged tree it is very conspicuous. At other times it may, of course, be also most completely hidden when the leaves are extra dense. Hutton says that in Mussoorie he sometimes found it built Low down in thick bushes.
The nest is a deep cup rather loosely and untidily put together. The outer part is constructed of twigs, sometimes mixed with roots and coarse grasses. The lining is made of roots, rachides, fine fibre or rarely of stout and fine grass-stems, while one nest obtained by Hume is said by him to have been made entirely of grass. Hume calls the nests moderately shallow cups, whilst nearly all other collectors say that it is rather deep. In comparison with the nests of some Magpies it is certainly deep, as most nests are a hemisphere or even deeper in proportion. An average nest would measure, externally and omitting all loose ends, about 6 inches by 3 in depth or rather more.
The eggs number three to five ; Marshall says the usual clutch is five, Hutton says three or four, Rattray found four to be the normal clutch though five and three were sometimes incubated. Both Jones and Dodsworth often found three incubated eggs in nests in the Simla States.
The eggs are typical Jay’s eggs and the range of variation small. The ground-colour is an olive-brown or olive-green, sometimes rather pale but generally dark compared with the colour of the ground in most Corvine eggs. The surface is stippled all over with freckles, generally most minute, less often becoming fairly well defined small blotches, of brown, which nearly always coalesce at the larger end to form a ring or small cap. Nearly always at this end also there are added a few twisted lines of black. In shape most eggs are true ovals, a little compressed at the smaller end, though broad blunt ovals are not uncommon.
Eighty-nine eggs average 28.8 x 22.0 mm. : maxima 32.0 x 22.1 and 28.6 x 24.5 mm. ; minima 26.1 x 21.0 and 27.8 x 20.0 mm.
