Dryocopus javensis javensis (Horsfield): Great Black Woodpecker.—Specimens, 4: Cocoa Research Station: ♀ old brood patch, 284.7 gm., light body and tail molt, July 6, 1962, MCT 2601; ♂ by plumage, July 19, 1962, MCT 2625; ♀, June 25, 1963, ADG 162; ♂, 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: ♂, 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: ♂, September 28, 1962, MCT 2975. 12 mi. N Kalabakan: ♂ 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: ♂, light body and wing molt, July 2, 1962, MCT 2575; ♂ testis 5 × 3 mm., 168.5 gm., July 23, 1962, MCT 2640; ♀, 176.1 gm., July 23, 1962, MCT 2641; ♂, 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 forest and dead trees in the cocoa fields.
Calyptomena viridis gloriosa Deignan: Green Broadbill.—Specimens, 10: Cocoa Research Station: ♀, 67.4 gm., August 1, 1962, MCT 2698; ♀, 53.2 gm., September 16, 1962, MCT 2927; ♀, May 6, 1963, ADG 106; ♂, June 18, 1963, ADG 148; ♀ by plumage, June 26, 1963, ADG 164. 12 mi. N Kalabakan: ♀, October 12, 1962, MCT 3015; ♀, October 20, 1962, MCT 3098; ♂, October 22, 1962, MCT 3122. Oil Palm Research Station: ♀, August 15, 1963, ADG 240. Pintasan: ♂, October 16, 1963, ADG 310.
Sight records of this species are evidently a poor indication of its abundance, because I saw but one in the field at the Cocoa Research Station, a male sitting in the top of cocoa tree about eight feet up. All the specimens were netted, and the number so taken indicates not only that the species is common but also that it frequents the lower levels of the forest as well as the tops of tall trees (as noted by Smythies, 1960:339).
