993. Gracupica burmanica

(993) Gracupica burmanica (Jerdon).
Gracupica burmanica, Fauna B. I., Birds, 2nd ed. vol. iii, p. 50.
This Red-billed Myna is found over practically the whole of Burma from Mt. Victoria in the Chin Hills, the Bhamo, Kachin Hills and Shan States to Tenasserim.
In Hume’s time the breeding of this very common Myna seems to have been unknown but, since then, Harington, Grant, Mackenzie and many others have taken their nests. Harington, when sending me a series of eggs from Maymyo, wrote :—“G. burmanica is the common Myna of Upper Burma in the jungles. It breeds both in holes in trees, in zyats and houses. I found a pair breeding in the verandah of the Kalawa Dak-bungalow in May, and outside the nest was the remains of the former tenant, suspended by the leg by a piece of string which had been used in the construction of the original nest. It breeds probably from April to June.”
Mackenzie took a fine series of its eggs in Maymyo, the Upper Chindwin and in the Lower Chindwin around Pakokku.
The nests are generally built in holes in, trees but many birds build in the temples and pagodas, while others habitually breed in houses, both deserted and occupied. Any hole seems to suffice, a brick dislodged from a wall—a snug corner under the eaves or between the rafters—while in trees natural hollows and the nest holes of Barbets and Woodpeckers are used, the latter being generally enlarged to suit the Myna’s bigger body. In some trees two or more birds may take up their abode and they apparently breed year after year in the same tree or building. The nest is merely an assemblage of all kinds of rubbish—grass, roots, leaves, rags and odd scraps pilfered from their human landlords. These are placed anyhow in the holes and there seems to be no attempt to form a definite lining of softer material, though there may be some feathers lying on the top of the others.
The breeding season is April and May and, less often, June.
The full clutch of eggs laid is four to five, while Mackenzie once obtained six.
In colour they are a bright turquoise-blue and vary very little in depth of colour. The texture is fine, hard and close and the eggs show none of the corrugations common on the surface of some Mynas’ eggs. In shape they are generally short, blunt ovals, rarely rather longer and more pointed.
Seventy eggs average 27.1 x 20.6 mm. : maxima 29.5 x 21.6 and 29.1 x 23.0 mm. ; minima 23.6 x 19.9 and 26.8 x 18.9 mm.
