221. Siva cyanuroptera, Hodgs. _The Blue-winged Siva_.

Siva cyanouroptera, _Hodgs., Jerd. B. Ind._ ii, p. 253; _Hume, Rough

Draft N. & E._ no. 617.

The Blue-winged Siva breeds, according to Mr. Hodgson's notes, in the

central regions of Nepal, and in the neighbourhood of Darjeeling, in

May and June. The nest is placed in trees, at no great elevation above

the ground, and is wedged in where three or four slender twigs make a

convenient fork. A nest taken on the 2nd June was a large compact cup,

measuring exteriorly 4·75 in diameter and 3·75 in height, and having

a cavity 2·6 in diameter and 1·87 in depth. It was composed of fine

stems of grass, dry leaves, moss, and moss-roots, bound together with

pieces of creepers, roots, and vegetable fibres, and closely lined

with fine grass-roots. They lay from three to four eggs, which are

figured as moderately broad ovals, considerably pointed towards the

small end, 0·85 in length by 0·6 in width, having a pale greenish

ground pretty thickly speckled and spotted, especially on the broader

half of the egg, with a kind of brownish brick-red.

Mr. Mandelli found a nest of this species at Lebong (elevation 5500

feet) on the 28th April. It contained four fresh eggs; it was placed

in a fork of a horizontal branch of a small tree at a height of only 3

feet from the ground. The nest is, for the size of the bird, a

large cup, externally entirely composed of green moss firmly felted

together. This outer shell of moss is thickly lined with the dead

leaves of a _Polypodium_, and this again is thinly lined with fine

grass. The nest was about 4 inches in diameter, and 2·5 in height

externally; the cavity was about 2·5 broad and 1·5 deep.

The nests of this species are very beautiful cups, very compact and

firm, sometimes wedged into a fork, but more commonly suspended

between two or three twigs, or sometimes attached by one side only to

a single twig. They are placed at heights of from 4 to 10 feet from

the ground in the branches of slender trees, and are usually carefully

concealed, places completely encircled by creepers being very

frequently chosen. The chief materials of the nest are dead leaves,

sometimes those of the bamboo, but more generally those of trees; but

little of this is seen, as the exterior is generally coated with moss,

and the interior is lined first with excessively fine grass, and then

more or less thinly with black buffalo- or horse-hairs. The cups are

about 3 inches in diameter and 2 in height externally, the cavities

barely 2 in diameter and perhaps 1·5 in depth: but they vary somewhat

in size and shape according to the situation in which they are placed

and the manner in which they are attached, some being considerably

broader and shallower, and some rather deeper.

Eggs of this species sent me from Mr. Mandelli, which were obtained by

him in the neighbourhood of Darjeeling, are decidedly elongated ovals,

fairly glossy, and with a pale slightly greenish-blue ground. A number

of minute red or brownish-red or yellowish-brown specks and spots

occur about the large end, sometimes irregularly scattered, sometimes

more or less gathered into an imperfect zone. The rest of the egg is

either spotless or exhibits only a few tiny specks and spots. The eggs

measure 0·75 and 0·76 by 0·51 and 0·52.
