(883) Acanthopneuste reguloides reguloides (Blyth).

This Warbler breeds from the frontiers of Afghanistan and Baluchi¬stan through Kashmir and the Outer Himalayas to Garhwal, Sikkim and Tibet, at all elevations from 6,000 to 10,000 feet and, in Garhwal, up to 12,000 feet.
I can find nothing on record about it breeding in India except Rattray’s very brief note in the Journ. Bomb. Nat. Hist. Soc. vol. xvi, but his notes to me are fuller and to the following effect:—
“Blyth’s Crowned Willow-Warbler is not uncommon in the Murree Hills, sometimes breeding as low as 6,000 feet elevation but, more often, between 7,500 and 9,000 feet. Possibly many nests are overlooked or at least unrecorded from their likeness to the nests and eggs of occipitalis, which is so common that collectors do not bother much about it. One can hardly say that they are forest birds but they are not found in open country and their favourite breeding sites seem to be between the stones and boulders of retaining walls of roads running through high forest. I have also seen their nests in buttresses and walls of bridges over ravines on these same roads, although both roads and bridges were in frequent use. Some¬times they breed in holes in trees, generally natural hollows in the stump of a tree, or in among the roots where they project from the bank. The nests are completely hidden ; those between the stones are generally well inside the wall, which has often to be partially dismantled before the nest is exposed. In the same way when built in trees they are usually right inside the hole and not visible from the outside.
“The birds breed during May and June, most birds laying between the 15th May and 15th June.
“The number of eggs in a clutch is four or five.
“The nest is a flimsy affair, domed, or perhaps roofed is a better word, as it so often seems to be more or less separate from the cup and occasionally non-existent. It is made principally of moss and grass, but may be mixed with leaves and roots, and is lined with moss and hair mixed, in one case with wool and hair. They stand no handling and fall to pieces when pulled out of the hole.
"The nests that I have seen have never been more than eight feet from the ground and most have been in low walls two or three feet up.”
Whymper found them breeding in Garhwal at 12,000 feet and twice shot the birds off their nests for identification. He describes one of their nests as “rather slight, of moss and lined with a little hair, domed and placed inside a cavity in a tree about 30 feet from the ground.”
These two nests were both taken on the 17th June.
The eggs are of the usual smooth but glossless white, broad to moderate ovals in shape and very fragile.
Thirty-six eggs average 15.6 x 12.1 mm. : maxima 17.1 x 12.2 and 14.4 x 12.4 mm. ; minima 14.2 x 11.1 mm.
