(833) Laticilla cinerascens (Walden).
THE ASSAM LONG-TAILED GRASS-WARBLER.
Laticilla cinerascens, Fauna B. I., Birds, 2nd ed. vol. ii, p. 431.
This Grass-Warbler is confined to the great grass-lands of Assam, both North and South of the Brahmapootra River, where it frequents the immense plains covered with "sun" or thatching grass and the almost equally great expanses of “ekra,” “nal” and elephant-grass, which are flooded during the whole of the rains.
The only ornithologist who has ever found its nest and eggs is Stevens, who took two nests in North Lakhimpur which he most generously handed over to me. With the nests he sent the following notes :—“I found these two nests, one in the last week of April and one in the first week of May, near Hessamara, North Lakhimpur, in one of the huge stretches of ‘ekra’ and ‘cagri’ growing on the sides of the Subansiri River and which are completely flooded all through the rains. In its actions the bird is just like a Prinia but is very secretive and, owing to the thickness of the matted reeds, it is very difficult to locate the nests, even when you have located the singing bird and know you are within a few yards of the nest.
“This is a deep, well-made cup composed of grass and lined with the flowering ends of grasses, placed low down in the small scrubby bushes which grow here and there, hidden in the vast sea of elephant- grass. The bird is common and I had hoped to find many more nests.”
The nests sent are as described by Stevens, untidy but compact cups, measuring a little over 4 by 2.1/2 inches deep outwardly and about 3 inches by 1.1/2 inch inwardly. The lining is neatly matted down and quite soft.
The four and three eggs contained in the two nests are like those of the preceding bird but have the ground-colour a quite strong slaty green, with the speckling almost black. They agree in shape and colour with the eggs of L. burnesi.
The average of the seven eggs is 16.9 x 13.9 mm. : maxima 17.2 x 14.1 mm. ; minima 16.6 x 14.0 and 17.0 x 13.6 mm.
