1631. Lyncornis cerviniceps cerviniceps

(1631) Lyncornis cerviniceps cerviniceps Gould.
THE BURMESE GREAT EARED NIGHTJAR.
Lyncornis cerviniceps cerviniceps, Fauna B. I., Birds, 2nd ed. vol. iv, p. 374.
This beautiful bird is found from Assam, South and East of the Brahmapootra ; Chittagong and Tippera in Eastern Bengal ; Manipur, the Lushai Hills and all Burma from the Chin, Kachin and Shan States to Tenasserim, and thence through the North of the Malay States. It also occurs in South-West Siam.
It is a bird of forests, but is often found in thin scrub, bamboo-jungle and especially in thin secondary growth surrounded by forest. Hopwood, writing to me of its haunts in Burma, says :— “The jungle was high forest, the trees consisting of Teak, Xylia dolabriformis, Terminalia, Homalium, etc., with bamboos, mostly
Stephalostachium pergracile ; in fact typical hill forest moderately dense. The situation in which the birds were breeding is a hill range between the Chindwin and Myittha Rivers. The forest is 10 or 12 miles wide, bounded on either side by open plains and cultivation, so it is evident that the birds breed in the high forest by preference and not of neccessity.”
In one month, March 1907, Hopwood found no less than five eggs in this piece of forest.
Davison, who was the first to find this bird’s egg, took it in “thin tree-jungle, almost free from brushwood, close to the village of Mala wan.”
Mackenzie took two eggs, one near Katba and one in Mergui in forest much like that described by Hopwood ; but two other eggs taken by him in the Upper Chindwin in April were both found in bamboo-jungle ; the only other egg I have was sent to me as an Owl’s egg from the Northern Malay States. The “Owl” was described as “an extraordinary bird ; she had a long tail and two upright ears and was very dark coloured,” the present bird of course.
The breeding season, so far as we know at present, is from January 10th (Davison.) to April 20th (Mackenzie). This last egg was almost hatching when taken.
There is no nest, the single egg being laid on the bare ground, though nearly always under the shelter of a clump of bamboos or a thick bush.
The eggs are typical Nightjar’s eggs and very beautiful when fresh, though they soon lose much of their colour. The ground varies from a pale yellow-cream to a beautiful rosy-salmon of considerable depth. The markings vary much inter se, but the surface is never heavily marked. Most eggs are marbled with pale grey. Some have this pale grey marbling only, while one or two have in addition further marbling and veining of pale bright reddish. One quite exceptional egg has, besides the very faint grey marbling, a few bold spots of red and reddish-brown at the larger end.
In shape the eggs are broad to long ellipses, only one showing distinctly smaller at one end. The texture is finer, closer and more fragile than in the eggs of Caprimulgus, and there is always a fine gloss.
Six eggs average 42.1 x 30.5 mm. : maxima 44.1 x 31.3 mm. ; minima 39.0 x 31.0 and 41.5 x 29.0 mm. ; an abnormally small egg measures only 35.3 x 26.9 mm. This is not included in the average.
The bird sits close and will sometimes remain on her egg until almost touched, staring wide-eyed at the intruder.
Nothing has yet been recorded as to manner or duration of incubation.
