Part 21

The first specimens that I obtained of the eggs of this species were kindly sent to me by the late Captain Mitchell and Mr. H.R.P. Carter of Madras; they were taken on the Nilghiris. They are moderately broad ovals, somewhat pointed towards one end, larger than the average eggs of T. lineatum, and about the same size as large specimens of the eggs of Crateropus canorus and Argya malcolmi. The ground-colour is of a delicate pale blue, and towards the large end, and sometimes over the whole surface, they are speckled, spotted, and blotched, but only sparingly, with brownish red and blackish brown, and amongst these markings a few cloudy streaks and spots of dull faint reddish purple are observable. The eggs have not much gloss.

Numerous other specimens subsequently received from Miss Cockburn and others correspond well with the above description. More or less pyriform varieties are common. In some eggs the markings are almost entirely wanting, there being only a very faint brownish-pink freckling at the large end; and in many eggs, even some that are profusely spotted all over, the markings consist only of darker or lighter brownish-pink shades. Occasionally a few, almost black, twisted lines are intermingled with the other markings, and in these cases the lines are frequently surrounded by a reddish-purple nimbus.

The eggs vary in length from 0·92 to 1·08, and in breadth from 0·74 to 0·8, but the average of twenty eggs measured was 1·0 by 0·76.

96. Trochalopterum fairbanki, Blanf. The Palni Laughing-Thrush.

Trochalopterum fairbanki, Blanf., Hume, Cat. no. 423 bis.

The Rev. S.B. Fairbank, the discoverer of this species, found its nest at Kodai Kanal, in the Palni Hills, in May. The nest was placed in the crotch of a tree, at about 10 feet from the ground, and at an elevation of nearly 6500 feet above the level of the sea. The eggs are moderately elongated ovals, with a fine, fairly glossy shell. The ground is pale greenish blue or bluish green; the markings are spots, small blotches, hair-lines, and hieroglyphic-like scrawls, rather thinly scattered about the surface, and varying in colour through several shades of brownish and reddish purple to bright claret-colour.

The only egg I have measures 1 inch in length by 0·8 inch in breadth.

99. Trochalopterum lineatum (Vig.). The Himalayan Streaked Laughing-Thrush.

Trochalopteron lineatum (Vig.), Jerd. B. Ind. ii, p. 50; Hume, Rough Draft N. & E. no. 425.

Next to the Common House-Sparrow, the Himalayan Streaked Laughing-Thrush is perhaps the most familiar bird about our houses at all the hill-stations of the Himalayas westward of Nepal and throughout the lower ranges on which these stations are situated; this species breeds at elevations of from 5000 to 8000 feet.

It lays from the end of April to the beginning of September, and very possibly occasionally even earlier and later. I took a nest on the 29th April near Mussoorie; Mr. Brooks obtained eggs in May and June at Almorah; Colonel G.F.L. Marshall at Mussoorie in July and August; and Colonel C.H.T. Marshall at Murree from May to the end of July. I again took them in July and August near Simla, and Captain Beavan found them as late as the 6th of September near the same station.

So far as my own experience goes, the nests are always placed in very thick bushes or in low thick branches of some tree, the Deodar appearing to be a great favourite. Those I found averaged about 4 feet from the ground, but I took a single one in a Deodar tree fully 8 feet up. The bird, as a rule, conceals its nest so well that, though a loose and, for the size of the architect, a large structure, it is difficult to find, even when one closely examines the bush in which it is. The nest is nearly circular, with a deep cup-like cavity in the centre, reminding one much of that of Crateropus canorus, and is constructed of dry grass and the fine stems of herbaceous plants, often intermingled with the bark of some fibrous plant, with a considerable number of dead leaves interwoven in the fabric, especially towards the base. The cavity is neatly lined with fine grass-roots, or occasionally very fine grass. The cavity varies from 3 inches to 3·5 in diameter, and from 2·25 inches to 2·75 in depth; the walls immediately surrounding the cavity are very compact, but the compact portion rarely exceeds from ·75 to 1 inch in thickness, beyond which the loose ends of the material straggle more or less, so that the external diameter varies from 5·5 inches to nearly 10.

The normal number of eggs appears to me to be three, although Captain Beavan cites an instance of four being found.

Captain Hutton tells us (J.A.S.B. xvii.) that in the neighbourhood of Mussoorie "this bird is met with in pairs, sometimes in a family of four or five, and may be seen under every bush. The nest is placed near the ground, in the midst of some thick low bush, or on the side of a bank amidst overhanging coarse grass, and not unfrequently in exposed and well-frequented places; it is loosely and rather slovenly constructed of coarse dry grasses and stalks externally, lined sometimes with fine grass, sometimes with fine roots. The eggs are three in number, and in shape and size exceedingly variable, being sometimes of an ordinary oval, at others nearly round."

From Almorah and Nynee Tal my friend Mr. Brooks writes to me "that this bird is common everywhere. The nest is generally placed in a low tree or bush where the foliage is thick. It is composed of grass, and lined with finer grass. The eggs are three in number, one inch and one line long by nine lines broad. They are of a light greenish blue, the tint being much the same as that of the eggs of Acridotheres tristis. They lay from the commencement of May to the end of June."

Colonel G.F.L. Marshall tells me that "the Streaked Laughing-Thrush is very common at Mussoorie, where it is called by the public the Robin of India. It breeds in July and August all about Landour. The nest is cup-shaped, rather shallow, and loosely put together, made of grass and fibre with some moss and a few dead leaves twisted into it; it is placed in a low bush or else on the ground concealed among the grass-roots on the hill-side. The eggs, three or four in number, are oval, rather large for the bird, and of a pure light-blue colour without spots. I took eggs on the 26th and 28th July and on the 16th August."

Sir E.C. Buck writes:--"At Mutianee, three marches north of Simla, I found on the 28th June a nest in a bush on the side of a scantily 'jungled' hill. It was 2 feet from the ground, constructed of grass and stalks externally, and lined with fibrous roots. It contained three fresh eggs. The nest measured--exterior diameter 6 inches, height exteriorly 4 inches; the interior diameter was 3 inches, and the depth of the cavity 2 inches."

The late Captain Beavan tells us that "on the 16th of August, 1866, I found a nest in the garden, in a rose-bush, with four pale blue eggs in it, like those of Acridotheres tristis. The nest is a large structure, firmly built of dry twigs, bark, sticks, ferns, and roots. Another nest, with three eggs only, was found in a thick clump of everlasting peas close to the ground on the 6th of September. The female sat very close, and this may have been the second nest of the same pair that built the nest mentioned above, as it was built not far from the first."

Major C.T. Bingham writes:--"Being at Landour for a few days in May I chanced on a nest of this bird, perhaps the commonest in the hills. It was placed under an overhanging bush on the side of Lal Tiba hill, and on the ground, being constructed rather loosely of pieces of the withered stem of some creeper, intertwined with a quantity of oak-leaves, and lined with grass-roots."

The eggs, of which I must have seen some hundreds, as this is the commonest Laughing-Thrush about both Mussoorie and Simla, are typically regular and moderately broad ovals. Abnormally elongated, spherical, and pyriform varieties occur; some are nearly round like a Kingfisher's, and I have seen one almost as slender as a Swift's, but, as a rule, the eggs vary but little either in shape or colour. They are perfectly spotless, moderately glossy, and of a delicate pale greenish blue, which of course varies a little in shade and intensity of colour, but which is very much paler on the average than those of any of the Crateropi, and at the same time less glossy. I am not at all sure whether T. lineatum is rightly associated with species like T. cachinnans, T. variegatum, and T. erythrocephalum, which all have spotted eggs.

In length the eggs vary from 0·8 to 1·13, and in breadth from 0·63 to 0·8; but the average of fifty-eight eggs carefully measured is 1·01 by 0·73.

101. Grammatoptila striata (Vig.). The Striated Laughing-Thrush.

Grammatoptila striata (Vig.), Jerd. B. Ind. ii; p. 11; Hume, Rough Draft N. & E. no. 382.

The Striated Laughing-Thrush, remarks Mr. Blyth, "builds a compact Jay-like nest. The eggs are spotless blue, as shown by one of Mr. Hodgson's drawings in the British Museum."

A nest of this species found near Darjeeling in July was placed on the branches of a large tree, at a height of about 12 feet.

It was a huge shallow cup, composed mainly of moss, bound together with stems of creepers and fronds of a Selaginella, and lined with coarse roots and broken pieces of dry grass. A few dead leaves were incorporated in the body of the nest. The nest was about 8 or 9 inches in diameter and about 2 in thickness, the broad, shallow, saucer-like cavity being about an inch in depth.

The nest contained two nearly fresh eggs. The eggs appear to be rather peculiarly shaped. They are moderately elongated ovals, a good deal pinched out and pointed towards the small end, in the same manner (though in a less degree) as those of some Plovers, Snipe, &c. I do not know whether this is the typical shape of this egg, or whether it is an abnormal peculiarity of the eggs of this particular nest. The shell is fine, but the eggs have very little gloss. In colour they are a very pale spotless blue, not much darker than those of Zosterops palpebrosus.

The eggs measure 1·3 and 1·32 in length, and 0·89 and 0·92 in breadth.
