485. Hemipus capitalis (McClelland). _The Brown-backed Pied Shrike_.

Hemipus capitalis (_McClell._), _Hume, cat._ no. 267 A.

I must premise that to the best of my belief there is no such thing

as _H. capitalis_, McClell., in India, or, in other words, that this

latter name is a mere synonym of _H. picatus_.[A]

[Footnote A: Mr. Hume would probably now agree with me that _H.

picatus_ and _H. capitalis_ are distinct species. _H. picatus_,

however, is not confined to Southern India, but occurs along the

Terais of Sikhim and Nepal, and throughout Burma. _H. capitalis_

occurs on the Himalayas from Gurwhal to Assam. There is little

doubt that Captain Hutton's nest did not really belong to a Pied

Shrike.--ED.]

Mr. Blyth remarks, Ibis, 1866:--"_Hemipus picatus_. Under this name

two very distinct species are brought together by Dr. Jerdon: _H.

capitalis_ (McClell., 1839; _H. picaecolor_, Hodgson, 1845) of the

Himalaya, which is larger, with proportionally longer tail, and has

a brown back; and _H. picatus_ (Sykes) of Southern India and Ceylon,

which has a black back. Mr. Wallace has good series of both of them.

"_Hemipus capitalis_ has accordingly to be added to the birds of

India."

Now, out of India, Mr. Wallace may have got hold of some brown-backed

_Hemipus_, which is really distinct, but nothing is more certain (I

speak after comparison of a large series from Southern India with a

still larger, gathered from all parts of the Himalayas) than that the

Southern and Northern Indian birds are identical, and that in both

localities the males have black and the females brown backs.

Capt. T. Hutton says:--"On the 12th of May I procured a nest of this

bird in the Dehra Doon; it was placed on the ground at the base of an

overhanging rock, and was composed entirely of the hair of horses and

cows and other cattle, which had doubtless been collected from the

bushes and pasture-lands in the vicinity. There were four eggs of a

pale sea-green, spotted with rufous-brown, and forming an indistinct

and nearly confluent ring at the larger end. The bird had begun to

sit.

"This curious little species is not uncommon in the outer hills up to

5000 feet in the summer months."

The three eggs sent me by Captain Hutton appear to differ somewhat

conspicuously from any other eggs of the _Laniidae_ that I have yet

seen. The ground-colour is a very pale greenish white, and they are

moderately thickly freckled and mottled all over, but most densely

towards the large end (where, in one egg, there is a well-marked,

though somewhat irregular, zone), with pale brownish pink and very

pale purple. In shape the eggs are very regular, rather broad ovals,

and appear to have but little or no gloss. They vary in length from

0·66 to 0·7 inch, and in breadth from 0·53 to 0·55 inch.

Dr. Jerdon's evidence, so far as it goes, tallies with Captain

Hutton's account. He says:--"I obtained its nest once at Darjeeling,

made of roots and grasses, with three greenish-white eggs, having a

few rusty-red spots."

From Sikhim, Mr. Gammie writes:--"At page 178 of 'Nests and Eggs of

Indian Birds' (Rough Draft), Captain T. Hutton's description of the

nest and eggs of _Hemipus picatus_ is given, and at page 179 that of

Mr. W. Davison. The two descriptions differ so radically that, as

there remarked, one of the two must be in error. Permit me to record

my limited experience of the nesting of this bird.

"Common as it is in Sikhim I have but once taken its nest, and that in

the first week of May, at 4000 feet elevation. The nest, which is well

described by Mr. Davison, is made of black, fibry roots, sparingly

lined with fine grass-stalks, and covered outwardly with small

pieces of lichens bound to the sides with cobwebs. It is a very neat

diminutive cup, measuring externally 1·9 inch across by an inch deep;

internally 1·5 by half an inch.

"The whole nest, although quite a substantially built structure, is

barely the eighth part of an ounce in weight. It was placed on the

upper side of a horizontal branch close to its broken end, about

fifteen feet from the ground, and contained two fresh eggs. I send

you the nest and an egg, both of which will, I think, be found on

comparison to agree exactly with those taken by Mr. Davison."

Mr. Mandelli has sent me two nests of this species, found on the 15th

August above Namtchu in Native Sikhim. They were placed about two feet

from each other, each in a small fork of the branches of a small tree

which was situated in heavy forest. Each contained two fresh eggs.

The nests are very similar, but one is rather larger and less tidily

finished-off than the other. Both are shallow cups, miniatures of some

of the nests of _Dicrurus_, composed of excessively fine grass-stems,

coated exteriorly all round the sides with cobwebs, and, in the case

of one of them, plastered exteriorly with tiny films of bark and dry

leaves like some of the nests of the _Pericrocoti_. Both have a little

soft silky vegetable down at the bottom of the cavity. The one nest is

about two inches, the other about two and a half inches in diameter

exteriorly, and both are a little less than three quarters of an inch

high outside. The cavity in the one is about an inch and a half, in

the other about an inch and three quarters in diameter, and both are

about half an inch deep.

Eggs received from Sikhim are broad ovals, glossless, with

greenish-white grounds, profusely speckled and mottled with slightly

varying shades of brown, here and there intermingled with dull, pale

inky purple. The markings are densest generally round the broadest

part of the egg. They measured from 0·61 to 0·7 in length, and from

0·51 to 0·55 in breadth.
