(99) Suthora webbiana brunnea.
Suthora brunnea Anderson, P. Z. S., 1871, p. 211 (Yunnan) ; Blanf. & Oates, i, p. 68, footnote.
Vernacular names. None recorded.
Description. The whole head and neck all round with the breast chestnut-brown, suffused with vinaceous below : the upper plumage, wing-coverts, tail and exposed parts of closed wing olive-brown; lower plumage yellowish brown.
Colours of soft parts. Iris deep red; bill yellow horny, pale except on the culmen ; legs greenish plumbeous or slaty brown.
Measurements. Total length about 125 to 130 mm.; wing 51 to 54 mm.; tail about 60 to 65 mm.; tarsus about 20 mm.; culmen about 7 mm.
Distribution. Yunnan and the Kachin Hills from Bhamo eastwards.
Nidification. This bird has been found breeding commonly in Sinlum-Kaba, Bhamo District, at an elevation of some 6,000 feet. Harington describes the nest as " a rather deep cup-shaped structure composed of bamboo-leaves and coarse blades of grass lined with finer grass and a few horse-hairs; measuring about 4" x 3 1/2" outside and 2" x 2" inside." The nests were all extremely well concealed and were only discovered by carefully watching the birds. They were placed in clumps of reeds or grass, or in thick bushes and tangles of creepers, in each case quite low down, less than three feet from the ground.
The eggs number 2 to 4, the former number having been taken much incubated, but 8 is the usual full clutch. In colour they are a rather deep, unspotted hedge-sparrows' egg-blue and in shape broad ovals, very little compressed at the smaller end. Twenty-four eggs average 16.3 x 12.8 mm.
The breeding season is from the end of April to early June.
Habits. Anderson's Suthora keeps principally to reed and grass cover, where they creep about but seldom fly. As they hunt for insects they keep up a continuous twittering, and they are more often heard than seen.
