A flock of four was seen on July 28, 1962, and on December 2, 1962,
I took three simultaneously in one mist net. The species has
flocking tendencies. Calls heard were a typical woodpecker rattle.

_=Dinopium rafflesi dulitense=_ Delacour: Olive-backed Three-toed
Woodpecker.--_Specimens_, 4: Cocoa Research Station: [Male] testis 11 x
7 mm., July 12, 1962, MCT 2620; [Male], September 6, 1962, MCT 2879. 12
mi. N Kalabakan: [Male], October 20, 1962, MCT 3097. Oil Palm Research
Station: [Male], August 12, 1963, ADG 227.

The species was taken in both primary and secondary forest. The
specimen collected at the Cocoa Research Station on July 12
suggests that the species breeds there.

_=Dryocopus javensis javensis=_ (Horsfield): Great Black
Woodpecker.--_Specimens_, 4: Cocoa Research Station: [Female] old brood
patch, 284.7 gm., light body and tail molt, July 6, 1962, MCT 2601;
[Male] by plumage, July 19, 1962, MCT 2625; [Female], June 25, 1963, ADG
162; [Male], May 26, 1963, ADG 112.

This species was common at the Cocoa Research Station. On June 30,
1962, a flock of six was moving through secondary forest. On July
6, 1962, I saw four in dead trees in one of the cocoa fields.

_=Mulleripicus pulverulentus pulverulentus=_ (Temminck): Great Slaty
Woodpecker.--_Specimen_, 1: Tiger Estate: [Male], November 25, 1962, MCT
3326.

I saw this species once at the Cocoa Research Station, where a
flock of four was feeding 30 feet up in secondary forest about 100
feet high on October 4, 1962.

_=Blythipicus rubiginosus parvus=_ Chasen and Kloss: Maroon
Woodpecker.--_Specimens_, 2: Cocoa Research Station: [Male], September
28, 1962, MCT 2975. 12 mi. N Kalabakan: [Male] imm., October 17, 1962,
MCT 3062.

I saw this bird sporadically while I was on the east coast. It
seemed to prefer secondary forest that had some undergrowth and was
invariably flushed from the understory.

_=Chrysocolaptes validus xanthopygius=_ Finsch: Orange-backed
Woodpecker.--_Specimens_, 4: Cocoa Research Station: [Male], light body
and wing molt, July 2, 1962, MCT 2575; [Male] testis 5 x 3 mm., 168.5
gm., July 23, 1962, MCT 2640; [Female], 176.1 gm., July 23, 1962, MCT
2641; [Male], September 28, 1962, MCT 2976.

This was one of the more common woodpeckers at the Cocoa Research
Station. I saw it throughout the period I was there, in secondary
