THE DULL GREEN WILLOW-WARBLER.

It is certainly most unfortunate for the older workers among us that Count Gyldenstolpe has discovered the type-specimen of
A. trochiloides and that two names so long known to us all as lugubris for this dark green bird and trochiloides for Blyth’s Crowned Willow-Warbler should in one case have to disappear and, in the other, to be changed. Let us hope the next generation will profit.
Very little is known about the breeding of this Warbler but it occurs in Summer from Garhwal to Eastern Tibet and still farther East in the Tsin-ling Mountains in Western China. I have had it reported from Kashmir but the report has never been con¬firmed.
Whymper found it breeding in the Birch forests at about 12,000 feet in Garhwal in the Nila Valley and later A. E. Osmaston took a nest in the Dhauli Valley in the same Hills, He writes (Journ. Bomb. Nat. Hist. Soc. vol. xxviii, p. 143, 1921) : —“I found it not uncommon in the Dhauli Valley from 11,500 to 12,500 feet elevation. Two of the specimens I obtained were identified for me at the British Museum, so there can, therefore, be no doubt about the identi-fication.
“During the breeding season the bird utters a loud Sparrow-like chirp repeated once or several times together. On the 26th June I found a nest with two fresh eggs. It was placed in a crevice in the side of an old Birch-tree about 6 feet from the ground, the tree being so situated that Birch-forests extended in one direction and open grassy slopes in the other. The nest was domed and was composed outside of moss with a little lichen. This was followed by a mixture of grass, lichen and moss, and there was a final lining of fine moss, mixed with just a few hairs and one or two small feathers. The eggs, which were pure white, average .62 x .47 inches.”
Rattray also records obtaining one nest at Murree on the 1st July, 1904, shooting the hen bird off the nest himself. “The nest was under the roots of a tree in a cutting ; the earth had been washed away, leaving a tangle of roots. Nest, a mass of moss, forming a cup with a neat lining of fine grasses. Eggs four, slightly incubated and pure white.” I have, unfortunately, not been able to trace these eggs.
A nest, with four eggs, taken by Capt. Kennedy near Gyantse on the 28th June, was completely domed, a ball about 6 inches across either way. The nest was exactly like that described above— outside moss and a little lichen, then a layer of grass and hair and, finally, a felted mass of tiny scraps of moss. It was placed on the ground at the foot of a tree on an almost open hill-side. The bird was, I understand, identified by Dresser, as well as by myself. The elevation was about 13,000 feet.
The four pure white eggs were of the typical texture and shape, and vary in size from 15.5 x 11.7 to 16.2 x 12.2 mm.
