205. Pomatorhinus olivaceus ripponi

(205) Pomatorhinus olivaceus ripponi Harington.
Pomatorhinus olivaceus ripponi, Fauna B. I., Birds, 2nd ed. vol. i, p. 210.
This Scimitar-Babbler breeds in the Shan States, Kachin Hills South to Karenni and, probably, still further South between 2,000 and 5,000 feet.
Its nest was first discovered by Bingham many years ago in the Thoungyeen Valley on the 4th March. He writes : “Having to go over the ground along the Southern boundary of the Meplay Reserve, I had to cut my way through dense bamboo. As I was slowly progressing along, bent almost double, out of a little hollow at my feet a bird flew with a suddenness that nearly knocked me down. I looked into the hollow, and there under the ledge of the sheltering bank was a nest of dry bamboo leaves, lined with strips of the same, shredded fine. It was cup-shaped, loosely made, about 1.1/2 inches in diameter and the same in depth, containing three pure white eggs.” The measurements must refer to the inside of the cup only. Later observers write of the nest as domed. Thus Cook (Journ. Bomb. Nat. Hist. Soc. vol. xxii, p. 262, 1913) : “Common in the grass land. I found two nests, the first on the 7th April containing three eggs on the point of hatching ; the second nest, also with three eggs, but quite fresh, I found on the 23rd. Both nests were globular in shape and composed of coarse grass loosely woven. The former was placed on sloping ground between the stems of a clump of tall grass ; the other nest was placed on flat ground, but amongst this grass. The nest was so moulded into a little depression that the top of the nest was but little above the surrounding ground-level. The eggs were pure white.”
Hopwood and Mackenzie found nests quite similar to the above at Maymyio on the 3rd and 9th May, both on the ground, and the year before, 1916, Osmaston also obtained a nest on the ground but in the middle of October, so this bird possibly has a double season, like many others of the genus. Wickham in the Southern Shan States took a nest on the 27th April which had been built on the top of a Pine-apple. This too was domed and made of bamboo-leaves.
They lay from two to four eggs, though three is probably the normal full clutch.
Eleven eggs average 24.9 x 17.9 mm. : maxima 25.8 x 18.4 and 25.5 x 19.0 mm. ; minima 24.0 x 17.2 and 24.6 x 17.1 mm.
Four eggs taken by Mackenzie and not included in the above are very small, measuring on an average only 21.25 x 15.5 mm., while the smallest is only 19.25 x 14.0 mm.
The eggs are, of course, pure white, like all other Scimitar- Babblers’, and are of the usual shape and texture.
