226. Zosterops palpebrosa (Temm.). _The Indian White-eye_.

Zosterops palpebrosus (_Temm.), Jerd. B. Ind._ ii, p. 265; _Hume,

Rough Draft N. & E._ no. 631.

The Indian White-eye, or White-eyed Tit as Jerdon terms it, breeds

almost throughout the Indian Empire, sparingly in the hotter and more

arid plains, abundantly in the Nilghiris and other ranges of the

Peninsula to their very summits, and in the Himalayas to an elevation

of 5000 or 6000 feet.

The breeding-season extends in different localities from January to

September, but I think that everywhere April is the month in which

most eggs are to be met with.

Sometimes they have two broods; whether this is always the case I do

not know.

The nest is placed almost indifferently at any elevation. I have taken

one from amongst the topmost twigs of a huge mohwa tree (_Bassia

latifolia_) fully 60 feet high, and I have found them in a tiny bush

not a foot off the soil. Still I think that perhaps the majority build

at low elevations, say between 2 and 6 feet from the ground.

The nest is always a soft, delicate little cup, sometimes very

shallow, sometimes very deep, as a rule suspended between two twigs

like a miniature Oriole's nest, but on rare occasions propped in a

fork. The nest varies much in size and in the materials with which it

is composed.

Pine grass and roots, tow, and a variety of vegetable fibres, thread,

floss silk, and cobwebs are all made use of to bind the little nest

together and attach it to the twigs whence it depends. Grass again,

moss, vegetable fibre, seed-down, silk, cotton, lichen, roots and the

like are used in the body of the nest, which is lined with silky down,

hair, moss, and fern-roots, or even silk, while at times tiny silvery

cocoons or scraps of rich-coloured lichen are affixed as ornaments to

the exterior.

One nest before me is a very perfect and deep cup, hung between two

twigs of a mohwa tree and almost entirely hidden by the surrounding

leaves. The exterior diameter of the nest is 2½ inches, and the depth

2 inches. The egg-cavity measures scarcely more than 1½ inch across

and very nearly as much in depth. It is composed of very fine

grass-stems and is thinly coated exteriorly with cobwebs, by which

also it is firmly secured to the suspending twigs, and externally

numerous small cocoons and sundry pieces of vegetable down are

plastered on to the nest. Another nest, hung between two slender twigs

of a mango tree, is a shallow cup some 2½ inches in diameter, and not

above an inch in depth externally. The egg-cavity measures at most 1½

inch across by three-fourths of an inch in depth. The nest is composed

of fine tow-like vegetable fibres and thread, by which it is attached

to the twigs, a little grass-down being blended in the mass, and

the cavity being very sparsely lined with very fine grass-stems. In

another nest, somewhat larger than, the last described, the nest is

made of moss slightly tacked together with cobwebs and lined with

fine grass-fibres. Another nest, a very regular shallow cup, with an

egg-cavity 2 inches in diameter and an inch in depth, is composed

almost entirely of the soft silky down of the _Calatropis gigantea_,

rather thickly lined with very fine hair-like grass, and very

thinly-coated exteriorly with a little of this same grass, moss, and

thread. Another, with a similar-sized cavity, but nearly three-fourths

of an inch thick everywhere, is externally a mass of moss, moss-roots,

and very fine lichen, and is lined entirely with very soft and

brilliantly white satin-like vegetable down. Another, with about the

same-sized cavity, but the walls of which are scarcely one-fourth of

an inch in thickness, is composed _entirely_ of this satiny down,

thinly coated exteriorly and interiorly with excessively fine

moss-roots (roots so fine that most of them are much thinner than

human hair); a few black horsehairs, which look coarse and thick

beside the other materials of the nest, are twisted round and round in

the interior of the egg-cavity. Other nests might be made entirely of

tow, so far as their appearance goes; and in fact with a very

large series before me, no two seem, to be constructed of the same

materials.

I have nests before me now, taken in September, March, June, and

August, all of which when found contained eggs.

Two is certainly the normal number of the eggs; about one fifth of the

nests I have seen contained three, and once only I found four.

From Murree Colonel C.H.T. Marshall informs us that he took the eggs

in June at an elevation of about 6000 feet.

Colonel G.F.L. Marshall says:--"I have taken eggs of this species at

Cawnpore in the middle of June. I found six nests, five of which were

in neem-trees. I also found the nest in Naini Tal at 7000 feet above

the sea, with young in the middle of June; one only of all the nests I

have seen was lined, and that was lined with feathers: they were, as a

rule, about eight feet from the ground, but one was nearly forty feet

up."

Capt. Hutton gives a very full account of the nidification of this

species. He says:--"These beautiful little birds are exceedingly

common at Mussoorie, at an elevation of about 5000 feet, during

summer, but I never saw them much higher. They arrive from the plains

about the middle of April, on the 17th of which month I saw a pair

commence building in a thick bush of _Hibiscus_, and on the 27th

of the same month the nest contained three small eggs hard-set. I

subsequently took a second from a similar bush, and several from

the drooping branches of oak-trees, to the twigs of which they were

fastened. It is not placed on a branch, but is suspended between

two thin twigs, to which it is fastened by floss silk torn from the

cocoons of _Bombyx Huttoni_, Westw., and by a few slender fibres of

the bark of trees or hair according to circumstances.

"So slight and so fragile is the little oval cup that it is

astonishing the mere weight of the parent bird does not bring it to

the ground, and yet within it three young ones will often safely

outride a gale that will bring the weightier nests of Jays and

Thrushes to the ground.

"Of seven nests now before me four are composed externally of little

bits of green moss, cotton, and seed-down, and the silk of the wild

mulberry-moth torn from the cocoons, with which last material,

however, the others appear to be bound together within. The lining of

two is of the long hairs of the yak's tail, two of which died on the

estate where these nests were found, and a third is lined with

black human hair. The other three are formed of somewhat different

materials, two being externally composed of fine grass-stalks,

seed-down, and shreds of bark so fine as to resemble tow; one is lined

with seed-down and black fibrous lichens resembling hair, a second is

lined with fine grass, and a third with a thick coating of pure white

silky seed-down. In all the seven, the materials of the two sides are

wound round the twigs, between which they are suspended like a cradle,

and the shape is an ovate cup, about the size of half a hen's egg

split longitudinally. The diameter and depth are respectively 2 inches

and 1½ inch by three-fourths of an inch. The eggs are usually three in

number."

Mr. Brooks, writing from Almorah, says:--"This morning, 28th April,

I found a nest of _Zosterops palpebrosa_ containing two fresh eggs.

Yesterday I found one of the same bird containing three half-fledged

young ones. Near the Tonse River, in the Allahabad District, I found

these birds in July nesting high in a mango-tree, the nest suspended

like an Oriole's to several leaves; now I find it in low bushes, at

heights of from 3 to 5 feet from the ground. The eggs, as before,

skim-milk blue, without markings of any kind."

From Gurhwal Mr. R. Thompson says:--"A small cup-shaped elegant nest

is built by this bird suspended by fastenings from the fork of a low

branch. The nest is about 2½ inches in diameter and three-fourths of

an inch in depth, composed of cobwebs, fine roots, hairs, &c., neatly

interwoven and lined internally with vegetable down. The eggs, two,

three, or four in number, are of a pale whitish-blue, oval, and

somewhat larger than those of _Arachnechthra asiatica_. The birds

select all kinds of trees, but the nest is always suspended. The

breeding-season is about March and April, and the brood is quickly

hatched and fledged.

"A nest found by me on the 22nd April, and containing four eggs, was

built most ingeniously in a creeper that hung from a small tree. The

birds had arranged it so that the long down-bearing tendril of the

creeper blended with the nest, which in the main was composed of the

material surrounding it.

"Another nest found on the 26th contained three young ones. It was

built in a low branch of a large mango-tree, and might have been 12

feet from the ground. It was a neat compact structure, deeply hollow,

and made up of cobwebs, fine straw, and hair, and lined with vegetable

down, closely and neatly interwoven.

"The parent birds were evidently feeding the young on the ripe fruit

of the _Khoda_ or _Chumroor_ (_Ehretia laevis_). I got one fruit from

the old birds, being anxious to know what the young ones were getting

for their dinner.

"The pairing-season commences about the end of March, when the males

may be heard uttering a feeble kind of rambling song, which in reality

is merely modified repetitions of a single note."

Mr. A. Anderson remarked that "the White-eye breeds throughout the

North-Western Provinces and Oudh during the months of June, July, and

August. The nest is a beautiful little model of the Oriole's; and

according to my experience it is invariably _suspended_, and _not

fixed in the fork of small branches_ as stated by Jerdon. I have on

several occasions watched a pair in the act of building their nest.

They set to work with cobwebs, and having first tied together two or

three leafy twigs to which they intend to attach their nest, they then

use fine fibre of the _sun_ (_Crotalaria juncea_), with which material

they complete the outer fabric of their very beautiful and compact

nest. As the work progresses more cobwebs and fibre of a silky kind

are applied externally, and at times the nest, when tossed about by

the wind (sometimes at a considerable elevation), would be mistaken by

a casual observer for an accidental collection of cobwebs. The inside

of the nest is well felted with the down of the madar plant, and then

it is finally lined with fine hair and grass-stems of the softest

kind. Sometimes the nest is suspended from only two twigs, exactly

after the fashion of the Mango-birds (_Oriolus kundoo_); and in this

case it is attached by means of silk-like fibres and fine fibre of

_sun_ for about 1½ inch on each side; at others it is suspended from

several twigs; and occasionally I have seen the leaves fixed on to the

sides of the nest, thus making it extremely difficult of detection.

"In shape the nest is a perfect hollow hemisphere; one now before me

measures (inside) 1·5 in diameter. The wall is about 0·3 in thickness.

"Almost all my nests have been built on the neem tree, the long

slender _petioles_ of which are admirably adapted for its suspension.

"As a rule the nest is built at a considerable height, and owing

to its situation there is not a more difficult nest to take. Great

numbers get washed down in a half-finished state in a heavy fall of

rain.

"The eggs are, exactly as Jerdon describes them, of a pale blue,

'almost like skimmed milk,' and the usual number is three, though four

are frequently laid."

"On the 7th September," writes Mr. E.M. Adam, "in my garden in

Lucknow, I discovered a nest of this bird in course of construction,

but when it was nearly finished the birds left it. The nest was a

beautiful little cup made of fine grass and cobwebs. It was situated

in a slender fork of a mango-tree about 15 feet from the ground."

Major C.T. Bingham says:--"Common both at Allahabad and at Delhi;

breeds in both places in May, June, and July. All nests I have seen

have been finely made little cups of fibres, bits of thread and

cobwebs, lined interiorly with horsehair, generally suspended between

two slender twigs at no great height from the ground."

Mr. E. Aitken writes:--"I have only actually taken one nest of the

White-eye. That was in Poona (2000 feet above the sea) on the 21st

July. The bird, however, builds abundantly in Poona about gardens,

trees on the roadside, &c.

"This particular nest was fixed to a thin branch of a tamarind-tree on

the side of a lane among gardens. It was within reach of my hand, and

was attached both to the thin branch itself and to two twigs. It was

well sheltered among leaves.

"The nest was a cup rather narrower at the mouth than in the middle.

Its external diameter at the top was 2½ inches; internal diameter 1½

inch; depth 1½ inch internally. It was composed of a variety of fibres

closely interwoven with some kind of vegetable silk, and was lined

principally with horsehair and very fine fibres. It contained three

eggs."

Mr. Davison tells us that "the White-eye breeds on the Nilghiris in

February, March, April, and the earlier part of May.

"The nest is a small neat cup-shaped structure suspended between a

fork in some small low bush, generally only 2 or 3 feet from the

ground, but sometimes high up, about 20 or 30 feet from the ground. It

is composed externally of moss and small roots and the down from the

thistle; the egg-cavity is invariably sparingly lined with hair. The

eggs, two in number, are of a pale blue, like skimmed milk."

From Kotagherry Miss Cockburn remarks:--"Their nests are, I think,

more elegantly finished than those of any of the small birds I have

seen up here. They generally select a thick bush, where, when they

have chosen a horizontal forked branch, they construct a neat round

nest which is left quite open at the top. The materials they commence

with are green moss, lichen, and fine grass intertwined. I have even

found occasionally a coarse thread, which they had picked up near some

Badagar's village and used in order to fasten the little building

to the branches. The inside is carefully lined with the down of

seed-pods. White-eyes' nests are very numerous here in the months of

January, February, and March. They are extremely partial to the wild

gooseberry bush as a site to build on. One year I found ten out of

eleven nests on these bushes, the fruit of which is largely used by

the aborigines of the hills. A pair once built on a thick orange-tree

in our garden. We often stood quite close to one of them while sitting

on the eggs, and it never showed the slightest degree of fear. They

lay two eggs of a light blue colour."

Mr. Wait, writing from Conoor, says that "_Z. palpebrosa_ breeds in

April and May, building in bushes and shrubs, and making a deep round

cup-shaped nest very neatly woven in the style of the Chaffinch,

composed of moss, grass, and silk cotton, and sparsely lined with very

fine grass and hair. The eggs are two in number, of a roundish oval

shape, and a pale greenish-blue colour."

Finally Colonel Legge informs us that this species breeds in Ceylon in

June, July, and August.

The eggs are somewhat lengthened ovals (occasionally rather broader),

and a good deal pointed towards the small end. The shell is very fine

but almost glossless; here and there a somewhat more glossy egg is met

with. They are normally of a uniform very pale blue or greenish blue,

without any markings whatsoever, but once in a way an egg is seen

characterized by a cap or zone of a somewhat purer and deeper blue.

Abnormally large and small specimens are common. They vary in length

from 0·53 to 0·7, and in breadth from 0·42 to 0·58; but the average of

thirty-eight eggs is 0·62 by 0·47, and the great majority of the eggs

are really about this size.
