Part 47 (1/2)
At the larger end they have an irregular zone of small, more or less confluent, spots and specks of this red, mingled with reddish or brownish purple, and a few specks and spots of the red scattered over the rest of the surface of the egg.
This egg may also be well described, as regards colour and mode of marking, by saying that it resembles the ill.u.s.tration in Hewitson's work of the eggs of _Parus cristatus_, except that the egg of _P.
proregulus_ has a distinct zone of nearly confluent spots, and their colour is more of a brownish red than those shown in the plate above referred to, which by-the-by do not correctly represent the colour of the spots upon the eggs of _P. cristatus_ which I have seen. These spots are coloured with too much of a tendency towards crimson instead of brownish red.
Three of the eggs taken by Captain c.o.c.k varied from 053 to 055 in length, and from 043 to 044 in breadth.
416. Phylloscopus subviridis (Brooks). _Brooks's Willow-Warbler_.
Reguloides subviridis, _Brooks, Hume, cat._ no. 566 bis.
Colonel Biddulph remarks that this species is common in Gilgit at 5000 feet in March, April, May, and beginning of June, and that it breeds in the Nulter valley in July at 10,000 feet. Young birds were shot in August fully fledged.
Major Wardlaw Ramsay observes on the label of a specimen procured by him at Bian Kheyl in Afghanistan in April, ”evidently breeding”; and on that of another specimen shot in May at the same place, ”contained eggs nearly ready to lay.”
418. Phylloscopus humii (Brooks). _Hume's Willow-Warbler_.
Reguloides humii, _Brooks, Hume, cat._ no. 565 bis.
Reguloides superciliosus (_Gm), Hume, Rough Draft N. & E._ no. 565.
Mr. Brooks and Captain c.o.c.k are the only persons I know of who have taken the eggs and nests of this species. The nest and eggs sent to and described by me in 'The Ibis' as belonging to this bird cannot really have pertained to it.
Mr. Brooks tells us that _P. humii_ ”is very abundant in Cashmere, and I believe in all hills immediately below the snows. It would be vain to look for this bird at elevations below 8000 feet, or at any distance from the snows. It was common even in the birch woods above the upper line of pines. I found many nests. It builds a globular nest of coa.r.s.e gra.s.s on a bank side, always on the ground, and never up a tree. The nest is lined with hair in greater or lesser quant.i.ties.
The eggs, four or five in number, average 56 by 44, are pure white, profusely spotted with red, and sometimes have also a few spots of purplish grey. On the 15th June I found a nest with four young ones on the south side of the Pir-Pinjal Pa.s.s. This bird has no song, only a double chirp in addition to its callnote. The double chirp, which is very loud, is intended for a song, for the male bird incessantly repeats it as he feeds from tree to tree near where the female is sitting upon her nest.”
Nests of this species obtained in Cashmere towards the end of May and during June near Goolmerg, and brought me by Mr. Brooks, were certainly by no means worthy of this pretty little Warbler. They are very loosely made, more or less straggling cups of somewhat coa.r.s.e gra.s.s, only slightly lined interiorly with fine moss-roots. The egg-cavity is very small compared with the size of the nest, some of which, look like b.a.l.l.s of gra.s.s with a small hole in the centre. They average from 4 to 5 inches in external diameter, and from 2 to 3 inches in height. The egg cavity does not exceed 2 inches in diameter, and seems often to be less, and is from an inch to half an inch in depth.
From Cashmere, when in the thick of the nests of this species, Mr.
Brooks wrote to me as follows:--
”From Goolmerg, which is at the foot of a snowy range, I went up to the foot of the snows through pine-forests. The pines ceased near the snow and were replaced by birch wood on tremendously rocky ground, which bothered me greatly to get over. I had missed _P. humii_ after leaving the foot of the hill, where water was plentiful, but here again the bird became abundant. I could not, however, find a nest here, though I watched several pairs. I think in the cooler country they breed later. Flowers which had gone out of bloom below I again met with up here in full flower.
”Blyth says: '_R. superciliosus_ has not any song, unless a sort of double call, consisting of two notes, can be called a song,' This the males vigorously uttered all day long, but I did not notice this much; but as soon as the female sharply and rapidly uttered the well-known bell-like call, I knew she was disturbed from her nest, or had left it of her own accord. Whichever of us heard this rushed quickly to the spot, and the female once sighted was kept in view as she flitted from tree to tree, apparently carelessly feeding all the while; soon she came lower down to the bashes below, and now her note quickened and betokened anxiety; generally before half an hour would elapse she would make a dash at a particular spot, and wish to go in but checked herself. This would be repeated two or three times, and now the nest was within the compa.s.s of 2 or 3 yards. At last down she went and her note ceased. When all had been quiet for a minute or two, the male meanwhile continuing his double note in the trees above, I cautiously approached the place. Sometimes the nest was very artfully concealed, but other times there it was--the round green ball with the opening at one side. I often saw the female put her head out and then partially draw it in again. Her well-defined supercilium was very distinct. I thought I could catch her on the nest once, and went round above her, but out came her head a little further, and she bolted as I brought down my pocket handkerchief on the nest. I shot one or two from the nest, but this I found unnecessary. In every case the female shouted vigorously on leaving the nest or immediately after, and by her very peculiar note fully authenticated the eggs.”
Elsewhere Mr. Brooks has remarked:--”Goolmerg is one of those mountain downs, or extensive pasture lands, which are numerous on the top of the range of hills immediately below the Pir-Pinjal Range, which is the first snowy range. It is a beautiful mountain common, about 3000 feet above the level of Sirinugger, which latter place has an elevation of 5235 feet. This common is about 3 miles long and about a couple of miles wide, but of very irregular shape. On all sides the undulating gra.s.s-land is surrounded by pine-clad hills, and on one side the pine-slopes are surmounted by snowy mountains. On the side near the snow the supply of water in the woods is ample. The whole hill-side is intersected by small ravines, and each ravine has its stream of pure cold water--water so different from the tepid fluid we drink in the plains. In such places where there were water and old pines _P. humii_ was very abundant: every few yards was the domain of a pair. The males were very noisy, and continually uttered their song.
This song is not that described by Mr. Blyth as being similar to the notes of the English Wood-Wren (_P. sibilatrix_) but fainter--it is a loud double chirp or call, hardly worthy of being dignified with the name of song at all. While the female was sitting, the male continued vigorously to utter his double note as he fed from tree to tree. To this note I and my native a.s.sistants paid but little attention; but when the female, being off the nest, uttered her well-known '_tiss-yip_,' as Mr. Blyth expresses the call of a Willow-Wren, we repaired rapidly to the spot and kept her in view. In every instance, before an hour had pa.s.sed, she went into her nest, first making a few impatient dashes at the place where it was, as much as to say--'There it is, but I don't want you to see me go in.'
”The nest of _P. humii_ is always, so far as my observation goes placed on the ground on some sloping bank or ravine-side. The situation preferred is the lower slope near the edge of the wood, and at the root of some very small bush or tree; often, however, on quite open ground, where the newly growing herbage was so short that it only partially concealed it. In form it is a true Willow-Wren's nest--a rather large globular structure with the entrance at one side.
Regarding the first nest taken, I have noted that it was placed on a sloping bank on the ground, among some low ferns and other plants, and close to the root of a small broken fir tree which, being somewhat inclined over the nest, protected it from being trodden upon. It was composed of coa.r.s.e dry gra.s.s and moss and lined with finer gra.s.s and a few black hairs. The cavity was about 2 inches, and the entrance about 1 inch in diameter. About 20 yards from the nest was a large, old, hollow fir tree, and in this I sat till the female returned to her nest. My attendant then quietly approached the spot, when she flew out of the nest and sat on a low bank 2 or 3 yards from it: then she uttered her '_tiss-yip_,' which I know so well, and darted away among the pines. My man retired, upon which she soon returned, and having called for a few minutes in the vicinity of the nest, she ceased her note and quickly entered. Again she was quietly disturbed, and sat on a twig not far from the nest. I heard her call once more, and then shot her. There were five eggs, which were slightly incubated.
”My second nest was placed on the side of a steep bank on the ground.
The third was similarly placed, and composed of coa.r.s.e gra.s.s and moss, and lined with black horsehair. In each of these nests the number of eggs was five.
”Another nest, taken on the 1st June, with four eggs, was placed on the ground on a sloping bank, at the foot of a small thin bush. It was composed as usual of coa.r.s.e dry gra.s.s and moss, and lined with finer gra.s.ses and a few hairs. The eggs were five or six days incubated.
”Another nest, with four eggs, was placed on the ground, under the inclined trunk of a small fir. The same materials were used.
”Another nest, containing four eggs, was placed on a sloping bank and quite exposed, there being little or no herbage to conceal it. It was composed as before, with the addition of a few feathers in the outer portion of the nest.
