The only district from which this bird’s breeding has been recorded is the Khasia Hills, where it was first discovered. I never saw it breeding in the adjoining North Cachar Hills, though it must surely do so there and in other suitable places in the hills South of the Brahmapootra.
All my nests have been taken between the 15th May and 21st June at elevations between 2,000 and 4,000 feet. They were found either in bamboo-jungle or in dense evergreen forest with thick and tangled undergrowth and all in very broken country, steep hillsides with rocky ravines. When in bamboo-jungle they were placed in bamboo clumps, fixed into the masses of little twigs which shoot from all the lower nodes and often more or less hidden among the debris of fallen leaves. When in evergreen-jungle they were built either in very thick bushes, low down, or in tangles of raspberry vines and other creepers.
The nests are tiny cups, neat and compact, with proportionately bulky sides and bottom, which measure about 4 inches across and about 3 inches or rather less in depth. The outer part is made of fine strips of bamboo-leaves and grass, very fine grass-stems and a fibrous material, possibly fine aerial roots of bamboos. The whole are closely interwoven and then coated with spiders’ webs. The lining is of very fine grass stems or hair-like roots very neatly finished off. The height at which they are placed varies from a few inches to about 2 feet from the ground.
The eggs number two to four and are in colour a beautiful pale blue with a soft fine texture and surface, but without gloss. In shape they are typically short broad ovals but a few are somewhat longer and more pointed at the smaller end.
Twenty eggs average 15.7 x 11.9 mm. : maxima 17.0 x 12.2 and 15.3 x 12.3 mm. ; minima 15.0 x 12.0 and 15.6 x 11.3 mm.
They are very like the eggs of Zosterops but darker and less glossy, whilst they differ from the blue eggs of Franklinia in being a less bright blue and in having no gloss.
