THE YUNNAN, or ANDERSON’S, OLIVE-BROWN SUTHORA.
Suthora webbiana brunnea, Fauna B. I., Birds, 2nd ed. vol. i, p. 112.
This Suthora is found from the Kachin Hills to Yunnan. Captain Harington obtained this bird breeding in great numbers round Sinlum Kaba at 6,000 feet in 1905 and, later in 1909 and 1910, Captain Tancock also procured a series of its eggs.
Captain Harington records his notes on its nidification as follows (Journ. Bomb. Nat. Hist. Soc. vol. xvi. p. 740, 1906):—
“ I was fortunate in finding four nests of this interesting little bird, up at Sinlum Kaba (6,000 feet), Bhamo District, Upper Burma. The first nest was found on the 30th May in a patch of reeds growing in the Government garden. The birds first attracted my attention by their continuous twittering, while my dog was working in some long grass and reeds growing in a swamp. I felt certain there was a nest somewhere near so, carefully marking the spot, I went away. On returning sure enough a bird got up somewhere, but it was impossible to say where until, by repeating the practice three or four times, I was fortunate at last in seeing the exact clump from which the bird came out, and so found the nest, which was placed in the middle of a clump of reeds, about 18" from the ground, and so well concealed that it would have been impossible to find unless the bird had been seen leaving. It took me the whole afternoon to find the nest and shoot the bird. The nest was rather a deep cup-shaped structure composed of bamboo leaves and coarse blades of grass, lined with finer grass and a few horse-hairs, measuring about 4" by 3.1/2" outside, 2" x 2" inside. It contained three highly incubated eggs of a bright pale blue.
“The other nests were easier to find after the bird’s notes and habits were known, as in each case they drew attention to their whereabouts by their twittering. I used then to mark the spot with a stick and go away and sit down ; as soon as all was quiet I came back, when the noise would begin again and eventually the bird would be seen leaving, when after a careful hunt most probably the nest would be found.
“The three nests were found near each other on the same spur of the hills on the 1st June, and were placed as follows :- One in a clump of thatching grass at about one foot from the ground, another placed on a bramble in some grass about two feet from the ground, and the third in a patch of grass growing under a thorn-bush, and contained 3 young birds, 3 eggs and 2 eggs, respectively. The eggs were hard set, but blowable.”
The eggs are similar to those of the Orange Suthora’s but larger and rather darker blue. One curious egg taken by Captain Tancock has a well defined cap of blue much darker than the rest of the egg.
Thirty-two eggs average 16.6 x13.1 mm. : maxima 18.2 x 14.0 and 17.9 x 14.1 mm. ; minima 15.0 x 12.2 and 15.7 x 12.1 mm.
