35. Aegithaliscus erythrocephalus (Vig.). _Red-headed Tit_.

Aegithaliscus erythrocephalus (_Vig._) _Jerd. B. Ind._ ii, p. 270;

_Hume, Rough Draft N. & E._ no. 634.

The Red-headed Tit breeds throughout the Himalayas from Murree to

Bhootan, at elevations of from 6000 to 9000 or perhaps 10,000 feet.

They commence breeding very early. I have known nests to be taken

quite at the beginning of March, and they continue laying till the end

of May.

The nest is, I think, most commonly placed in low stunted hill-oak

bushes, either suspended between several twigs, to all of which it is

more or less attached, or wedged into a fork. _I have_ found the nest

in a deodar tree, _laid_ on a horizontal bough. I have seen them in

tufts of grass, in banks and other unusual situations; but the great

bulk build in low bushes, and of these the hill-oak is, I think, their

favourite.

The nests closely resemble those of the Long-tailed Tit (_Acredula

rosea_). They are large ovoidal masses of moss, lichen, and

moss-roots, often tacked together a good deal outside with

cotton-wool, down of different descriptions, and cobwebs. They average

about 4½ inches in height or length, and about 3½ inches in diameter.

The aperture is on one side near the top. The egg-cavity, which may

average about 2¼ inches in diameter and about the same in depth below

the lower edge of the aperture, is densely lined with very soft down

or feathers.

They lay from six to eight eggs, but I once found only four eggs in a

nest, and these fully incubated.

From Murree, Colonel C.H.T. Marshall notes that this species "builds a

globular nest of moss and hair and feathers in thorny bushes. The eggs

we found were pinkish white, with a ring of obsolete brown spots at

the larger end. Size 0·55 by 0·43. Lays in May."

Captain Hutton tells us that the Red-cap Tit is "common at Mussoorie

and in the hills generally, throughout the year. It breeds in April

and May. The situation chosen is various, as one taken in the former

month at Mussoorie, at 7000 feet elevation, was placed on the side

of a bank among overhanging coarse grass, while another taken in the

latter month, at 5000 feet, was built among some ivy twining round a

tree, and at least 14 feet from the ground. The nest is in shape a

round ball with a small lateral entrance, and is composed of green

mosses warmly lined with feathers. The eggs are five in number, white

with a pinkish tinge, and sparingly sprinkled with lilac spots or

specks, and having a well-defined lilac ring at the larger end."

From Nynee Tal, Colonel G.F.L. Marshall writes:--"This species makes

a beautifully neat nest of fine moss and lichens, globular, with

side entrance, and thickly lined with soft feathers. A nest found on

Cheena, above Nynee Tal, on the 24th May, 1873, at an elevation of

about 7000 feet, was wedged into a fork at the end of a bough of a

cypress tree, about 10 feet from the ground, the entrance turned

inwards towards the trunk of the tree. It contained one tiny egg,

white, with a dark cloudy zone round the larger end.

"About the 10th of May, at Naini Tal, I was watching one of these

little birds, which kept hanging about a small rhododendron stump

about 2 feet high, with very few leaves on it, but I could see no

nest. A few days later I saw the bird carry a big caterpillar to the

same stump and come away shortly without it; so I looked more

closely and found the nest, containing nearly full-fledged young, so

beautifully wedged into the stump that it appeared to be part of it,

and nothing but the tiny circular entrance revealed that the nest was

there. It was the best-concealed nest for that style of position that

I have ever seen."

These tiny eggs, almost smaller than those of any European bird that

I know, are broad ovals, sometimes almost globular, but generally

somewhat compressed towards one end, so as to assume something of a

pyriform shape. They are almost entirely glossless, have a pinkish or

at times creamy-white ground, and exhibit a conspicuous reddish or

purple zone towards the large end, composed of multitudes of minute

spots almost confluent, and interspaced with a purplish cloud. Faint

traces of similar excessively minute purple or red points extend more

or less above and below the zone. The eggs vary from 0·53 to 0·58

in length, and from 0·43 to 0·46 in breadth; but the average of

twenty-five is 0·56 nearly by 0·45 nearly.
