Dicrurus nigrescens, _Oates; Oates, B.I._ i, p. 315.
Mr. Oates found the nest of this Drongo in Pegu. He says:--"I found
one nest on the 27th April at Kyeikpadein, near the town of Pegu, on
a small sapling near the summit. It contained four eggs[A]; they are
without gloss; the ground-colour in all is white. In three eggs the
whole shell is marked with spots of pale purple; these are perhaps
more numerous at the thick end, but not conspicuously so. The fourth
egg is blotched, not spotted, with the same colour.
[Footnote A: I recorded the nest and eggs of this bird under the name
of _Buchanga intermedia_ (S.F. v, p. 149). The parent birds of these
eggs are fortunately still in the British Museum, and I am able to
identify them with this species, which occurs generally throughout
Tenasserim and many parts of Lower Pegu.--ED.]
"The nest is composed of fine twigs and the dry branches of weeds; it
is lined very firmly and neatly with grass. Exterior diameter 5 inches
and depth 2; egg-chamber 3½ inches across and 1¼ deep. The outside
of the nest is profusely covered with lichens and cobwebs. The eggs
measure from ·83 to ·95 in length, and ·68 to ·71 in width."
