THE WHITE-THROATED, or AUSTEN’S, PARROT-BILL.
Paradoxornis guttaticollis Fauna B. I., Birds, 2nd ed. vol. i, p. 106.
This Parrot-Bill is found in the hills South and East of the Brahmapootra, extending into the Chin and Kachin Hills, Shan States and, thence, into Western China. This bird and the preceding species are very closely allied but seem to be good species, with much overlapping of breeding range. In South Assam both are common and all their habits and nidification seem to be identical but whereas this bird possibly never breeds below 3,000 feet and preferably not below 4,000 the preceding bird is found in the foot-hills and even into the Plains. Again the present bird ascends far higher. Rothschild’s collector found it in great numbers in Yunnan and actually obtained a specimen on the Shweli-Salwin Divide.
The White-throated Parrot-Bill differs in its nidification from the Black-throated Parrot-Bill only in haunting higher elevations and in being less restricted to bamboo, reed or grass jungles. In Laisung, North Cachar, I found them breeding in a narrow strip of bamboo-jungle running alongside the Laisung stream, between the stream and quite dense forest, into which the birds strayed and, sometimes, built.
The breeding season commences in April, in which month Grant took eggs in Bhamo on the 28th, whilst Mackenzie found nests, with one and two eggs respectively, on the 27th and 29th in the Chin Hills. May is, however, the principal breeding month, and in Assam, at all events, nine out of ten clutches are laid in that month.
They breed at least as high as 8,000 feet and, probably, 2,000 feet higher still and, on the other hand, are seldom, if ever, found nesting below 3,000 feet.
In the hills above Margherita in Assam Dr. Coltart and I took nests at a little below 3,000 feet but here, owing to the proximity of snow-topped mountains, we found most birds bred some 1,500 feet or so below their normal elevations. Harington found it breeding at 5,000 feet above Thaungyi.
It would be impossible to distinguish between the nests or eggs of the White-throated and Black-throated Parrot-Bills and even aberrant clutches follow the same lines.
Thirty-four eggs average 22.2 x 16.4 mm. : maxima 23.6 x 16.3 and 23.1 x 17.2 mm. ; minima 20.8 x 25.9 mm.
The eggs number two or three in a clutch, though once Captain Tancock took four eggs at Sinlum Kaba on the 4th May, 1908.
