ing a nest near Kalabakan, in a native kampong under the eave
of a house. There the birds were fastening the nest to the palm
thatching about 20 feet up and nearly over the door. Another pair
was nesting, close to the same house, about eight feet up in a
citrus tree. In Kalabakan proper, I saw a pair with fledgling young
in a croton bush about six feet from the door of a house, on
November 15, 1962. This nest was about seven feet up.

_=Lonchura malacca=_ (Linnaeus): Chestnut Munia.--_Specimens_, 6:
Tawau: [Female] imm., September 2, 1962, MCT 2862. Tenom: [Male],
January 6, 1963, MCT 3589. Tuaran: [Female], January 12, 1963, MCT 3594;
[Female], January 12, 1963, MCT 3595; hermaphrodite, testis 8 x 5 mm.,
largest ovum of ovary 2 mm., January 12, 1963, MCT 3596; [Female],
January 12, 1963, MCT 3597.

This was a common bird in the lowlands away from forest. I observed
it feeding on lawns in Tawau. A pair was building a nest on July
19, 1962, in an ironwood tree about 10 feet above the ground. The
nest was typically ball-shaped with a side entrance. This species
appears to stay in age groups when it flocks, as evidenced by the
large flocks of young in first-year plumage.

The hermaphroditic specimen was of some interest, since the ovary
and testis both seemed to be enlarged.
