Nidification. The late Mr. J. P. Cook took a nest of this species at Kalaw, Shan States, on the 7th of July. He describes it as made of dry pine-needles and moss, lined sparingly with wool and feathers, but so loosely built that it came to pieces in his hand on removal. It was placed, well concealed, in the head of a pine-sapling six feet from the ground, close to his house. The four eggs are pale greenish-blue, sparingly spotted with black at the larger end, with one or two hair-like streaks. They measure from 17.9 x 13.3 to 19.0 x 14.0 mm.
Habits. Forrest found this bird common in Yunnan between 9,000 and 12,000 feet in pine-forests but Mr. Cook obtained it at much lower elevations in the Shan Stares.
