This babbler was common in small groups at Quoin Hill. Whitehead
(1893:227) states that the species "frequents the true forest near
the ground." I observed these babblers only in sub-canopy trees, at
least 30 feet above the ground. Smythies (1960:419) stated that he
had never seen this species in the forest undergrowth.

This species was seen most often in primary forest undergrowth, but
occasionally as high as 10 feet up in small trees. I saw it also in
and around brush piles in secondary forest. The one specimen from
5.5 mi. SW Tenom was taken in the moss forest. MCT 2833 was in
heavy molt on the wings, head, and body.

_=Stachyris rufifrons sarawacensis=_ Chasen: Hume's Tree
Babbler.--_Specimen_, 1: Cocoa Research Station: [Male] testis 4 x 3
mm., November 28, 1962, MCT 3358.

There was no comparative material in the U. S. National Museum
where I studied the specimen but it fits Chasen's original
description of _S. r. sarawacensis_. H. G. Deignan (_in_ Peters _et
al._, 1964:303) considered this subspecies doubtfully distinct from
_S. r. poliogaster_.

The specimen was taken at a height of one and one-half feet in a
mist net set along a path. The bird was caught when it attempted to
cross the path from a patch of heavy undergrowth to a patch on the
other side. Mary Norman observed them at Kalabakan (Smythies,
1963:281) in saplings. They should probably be considered birds of
the unders
