(248) Pellorneum ignotum cinnamomeum Rippon.
THE SHAN PLAIN BROWN BABBLER.
Pellorneum ignotum cinnamomeum, Fauna B. I., Birds, 2nd ed. vol. i, p. 244.
This Babbler has been found in the Kachin Hills, Bhamo Hills and Shan States. Robinson and Kloss also record it at Dran, in Annam, so that it is sure to occur at suitable places between these two points. To the West Mackenzie and Hopwood obtained it breeding in the North Chin Hills.
Harington first found it breeding at Sinlum Kaba, in the Bhamo Hills, but reported it as rare, though since then Grant, Wickham and others have taken many nests, and consider the bird to be a common one.
The nests have been described by many collectors but, curiously enough, I can find no description of the country it inhabits, and the following summary is from notes supplied me by Mackenzie, Pershouse and others and sent me with eggs. They apparently do not haunt deep evergreen forest but, with this exception, may be found in almost any kind of cover between 3,500 and 7,000 feet, more often between 4,000 and 5,000 feet. Perhaps they prefer thin secondary growth, scrub- and bush-jungle and open bamboo- jungle, building in any of these. Pershouse, who obtained four nests in April and May at Sinlum, says : “I took two nests at Sinlum Kaba at about 500 ft. ; one was on the side of a bank and one on the ground moor a foot path, both being concealed in a thick tangle of grass, in the more open, or in what I should call the lesser jungle of trees, bamboos etc. The country at Sinlum is very varied ; there is dense tree forest and lesser and more open tree forest ; there is scrub jungle with patches of bamboo and there is one small tract all bamboo, whilst there are large open areas of bracken and white raspberries, dotted here and there with small ponds and patches of man thy ground with rushes etc. Of course there is also some secondary growth in abandoned cultivation.”
As regards the nest, this is very similar to that of the last bird, and is nearly always placed well off the ground in bushes, bamboos or long grass. Harington describes one nest as being “placed in long grass, about two feet from the ground, under some over¬hanging bamboos, domed shape, made of woven grass, and reminded one rather of a Suya’s nest.” Mackenzie obtained one nest “on the ground built into the roots of a tree from which the soil had been washed away,” but he says that “the nest is generally in the lowest branches of a thickish bush 1' to 4' high, being worked in with the grass around, if there is any. The nest is built of grass with a foundation of bamboo leaves and a lining of moss roots and is nearly always domed, often very slightly.”
The eggs, which number two or three, very rarely four (Mackenzie took one of this number in the N. Chin Hills), are like those of the preceding subspecies but, as a series, they are rather paler, many eggs being more terra cotta than brick-red in general appearance, whilst the pale violet-pink type so rare in cinnamomeum is more common in this.
Fifty eggs, including 22 taken by J. M. D. Mackenzie, average 20.4 x 15.0 mm. : maxima 21.5 x 15.0 and 21.1 x 15.9 mm. ; minima 18.5 x 14.7 and 21.3 x 14.4 mm.
