This little Flycatcher ranges during the breeding season from Nepal to Eastern Assam, Tibet and Kansu. Southwards it extends throughout the higher Burmese ranges to Tenasserim and peninsular Siam. It is not, however, certain that it breeds in these hills, and in the Himalayas it breeds at 6,000 feet upwards.
The only collector to take these eggs, recorded in Hume’s ‘Nests and Eggs,’ was Hodgson, who, to quote Hume, “figures the nest, placed on the stump end of a broad broken branch—a very massive, rather shallow pad, with a cup-shaped cavity composed of moss and lichens and lined with black roots. The nest is about 4 inches across and less than 2 high, and the cavity is a little less than 1-75 inch in diameter.”
Since Hume’s time there have been no further records, but Masson took two nests for me in 1909 which he sent me with the eggs and one of the parent birds. The two nests are quite well-made cups— not mere pads—of moss, both dried and green, but principally the latter, mixed with a few roots and with a few leaves at the base which may have been wind-blown into the hollows in which they were built. The lining was of fur—like rat-fur—very thick and matted into the bottom and sides of the cavities, which measured about 2.1/2 inches across by nearly 2 deep. Both nests were built in natural holes in living Birch-trees, one at 10 feet and the other at 15 from the ground.
The trees, it was said, were growing in fairly dense mixed forest at about 10,000 feet. Each nest contained three fresh eggs and were taken on the 9th and 10th June.
One clutch of eggs has a very pale grey-green ground, lightly freckled and blotched, principally at the larger end, with light reddish-brown. The second clutch has a clay ground and is freckled all over with slightly darker reddish, thick enough to make the eggs look uniform light reddish-brown at a little distance. The grain is very fine but the surface dull.
The six eggs average 17.1 x 12.2 mm. : maxima 17.6 x 12.1 and 16.9 x 12.7 mm. ; minima 16.8 x 12.1 and 17.4 x 12.0 mm.
