(929) Suya atrogularis khasiana Godw.-Aust.

Assam, South of the Brahmapootra, Manipur and the Lushai and Chin Hills comprise the breeding area of this Warbler. Where it meets and grades into the previous subspecies is not known.
This bird is extraordinarily common in the Khasia Hills and North Cachar Hills between 4,000 and 6,200 feet, wherever there are fairly wide stretches of grass or patches of low scrub mixed with grass. This species sometimes frequents fringes of forest where there is thick cover of bracken, grass and Daphne-bushes, often mixed with brambles. At the same time I have never found it inside forest unless there is a definite open space without big trees.
It occurred in North Cachar at 3,000 feet in Summer but was not common at this elevation, and did not breed below 3,500 feet. In the Khasia Hills it was very common between 3,500 feet and the highest peaks at 6,300.
It builds its nest generally in grass tufts, fixing the sides to two or more stems of grass, the materials being loosely wrapped round these and then drawn into the body of the nest itself. They are almost invariably domed and constructed like those of the preceding bird, and, like them, often have scraps of moss placed in the upper part of the dome. The three chief breeding months are April, May and June but I have taken eggs from March to October, and many birds must have three broods, for each of which they make a new nest within a short distance of the old one. I have more than once seen pairs of birds start building while they are still intermittently feeding their last brood.
Both sexes incubate and both take an equal share in building the nest and in feeding and looking after the young. Incubation takes ten days.
The eggs are exactly the same as those of the typical race and go through the same variations but, possibly, the green eggs do not outnumber the pink ones to quite the same extent. The commonest type in Criniger, pink mottled all over with reddish and with a deep confluent zone of dark red, is very seldom to be seen in the eggs of atrogularis.
The normal clutch is three to five, one number as often as the others, while I have taken a good many sixes and a few sevens.
Two hundred eggs average 17.0 x 12.8 mm. : maxima 18.3 x 14.0 mm. ; minima 16.0 x 12.2 and 16.1 x 12.0 mm.
