263. Criniger flaveolus (Gould). _The White-throated Bulbul_.

Criniger flaveolus (_Gould), Jerd. B. Ind._ ii, p. 83; _Hume. Rough

Draft N. & E._ no. 451.

A nest of this species sent me from Darjeeling was found in July, at

an elevation of about 3000 feet.

It was placed on the branches of a medium-sized tree, at a height of

only about 5 feet from the ground.

The nest was a compact, rather shallow saucer, 5·5 inches in diameter

and about 2 inches in height externally. The cavity was about 3·5 in

diameter and an inch in depth. The greater portion of the nest was

composed of dead leaves bound together firmly by fine brown roots;

inside the leaves was just a lining of rather coarser brown roots, and

again an inner lining of black horsehair-like roots and fine steins of

the maiden-hair fern.

The nest contained three fresh eggs. These eggs vary from broad to

somewhat elongated ovals, are more or less pointed towards the small

end, and exhibit a fine gloss.

The ground is a beautiful salmon-pink, and it is thinly spotted,

blotched, and marked with irregular lines of deep maroon-red. Most of

the markings in one egg are gathered into a very irregular straggling

zone round the large end, and the other egg exhibits a tendency to

form a similar zone. Besides these primary markings a few spots and

clouds of dull purple, looking as if beneath the surface of the shell,

are thinly scattered about the egg, chiefly in the neighbourhood of

the zone.

These eggs vary from 0·9 to 1·0 in length, and from 0·7 to 0·72 in

breadth.

Several nests of this species sent me by the late Mr. Mandelli and

obtained by him in British and Native Sikhim during July and the early

part of August are all precisely of the same type. They each contained

two fresh eggs; they were all placed in the branches of small trees in

the midst of dense brushwood or heavy jungle, at heights of from 4 to

10 feet from the ground. The nests are broad and saucer-like, nearly

5 inches in diameter, but not much above 2 in height externally; the

cavities average about 3·25 in diameter and about 1 in depth. The body

of the nest is composed of dead leaves, the sides are more or less

felted round with rich brown fibrous, almost wool-like roots; inside

the leaves fine twigs and stems of herbaceous plants, all of a uniform

brown tint, are wound round and round, apparently to keep the leaves

in their places interiorly, and then the cavity is lined with

jet-black horsehair-like vegetable fibres. What these are I do not

know, but they are precisely like horsehair to look at, only they are

comparatively brittle. The contrast of colour between the jet-black

lining and the rich brown of the lip of the saucer, which is constant

in all the nests, is very striking.

The eggs of this species sent me by Mr. Mandelli, obtained by him in

Sikhim at elevations of from 2000 to 4000 feet in July and the early

part of August, possess a very distinctive character. They are broad

ovals, much pointed towards the small end, and they are more glossy

than the eggs of any other of this family with which I am acquainted.

The ground-colour is pink. The markings consist of curious hair-line

scratches, clouded blotches, and irregular spots--in some eggs all

very hazy and ill-defined, in others more scratchy and sharp. The

great majority of the markings seem to be gathered together into

an irregular and imperfect zone round the large end. In colour the

markings vary from a deep brownish maroon to a dull brickdust-red,

sometimes they are slightly more purplish. In some eggs a few faint

clouds or small spots of subsurface-looking dusky purple may be

noticed mingled with the rest of the markings.

These eggs are totally unlike the eggs of _Criniger ictericus_. I have

never had an opportunity of verifying the eggs myself, but as three

different nests have now been taken, all containing precisely similar

eggs, I believe there can be no doubt of their authenticity.
