The Burmese Blue-winged Chloropsis is found over the whole of Burma, Siam and Cochin China, and also occurs in Manipur and the hills of the Surrma Valley, both in Cachar and the Khasia Hills. It is difficult to say what is the breeding elevation of this Chloropsis. The nests taken by myself have all been found between 2,500 and 4,000 feet, except one taken at 2,000 feet, but its status in the Assam hills is doubtful ; some winters one sees numbers, in other winters none at all. In those years in which it is fairly common in the Cold Weather a few pairs seem to breed in the hills but their breeding is never certain, and it would appear as if this bird was subject to local movements and periodic irruptions from Burma. I have been three years at a time in North Cachar without seeing a single specimen.
The birds I have found breeding have all been in evergreen forest and, unlike the species already dealt with, penetrate well into the interior, selecting trees far from any opening. The only excep¬tions to this are one or two nests I obtained from the thin evergreen forest at the foot of the Lilancote cliffs in very broken ground.
Like the other Chloropses, they place their nests at heights from 20 to 30 feet up in medium-sized or high trees, selecting two or three twigs or a small fork in one of the thin outer branches from which to suspend them. They only differ from the nests already described in having a greater variety of material used and in having the outside often much decorated with moss or lichen. One nest I found in the Khasia Hills was composed almost entirely of the red tendrils of a yellow Convolvulus mixed with grass, roots and a leaf or two ; a second was bound with dried weed-stems, in addition to the usual roots etc.
The earliest nest taken was on the 26th April, a few in May, none in June, and then one or two more in both July and August. It may be, therefore, that this Chloropsis has two broods in a year.
The eggs number two or three, generally two, and are like those of the aurifrons group, but two of the pairs in my series have a very pale ground.
Sixteen eggs average 22.3 x 15.5 mm. : maxima 23.2 x 15.4 and 22.3 x 16.0 mm. ; minima 21.0 x 14.4 mm.
