Cymbirhynchus macrorhynchus macrorhynchus (Gmelin): Black-and-Red Broadbill.—Specimens, 2: Kalabakan: ♂, November 16, 1962, MCT 3296. Tiger Estate: ♂, November 25, 1962, MCT 3321.
This species was seen only at Kalabakan, where I caught two in one net in dense secondary forest.
Eurylaimus ochromalus ochromalus Raffles: Black-and-Yellow Broadbill.—Specimens, 9: Cocoa Research Station: ♂, 32.0 gm., July 28, 1962, MCT 2682; ♂, 32.0 gm., August 1, 1962, MCT 2747; ♂, 33.8 gm., August 10, 1962, MCT 2753; ♀, 34.0 gm., September 11, 1962, MCT 2892; ♂, 34.7 gm., September 14, 1962, MCT 2926; ♀, September 26, 1962, MCT 2968; ♂, April 27, 1963, ADG 71. Agricultural Station Gum-Gum: ♀, September 26, 1963, ADG 284. Pintasan Agriculture Station: ♀, October 16, 1963, ADG 311.
This broadbill was common at the Cocoa Research Station in cocoa fields and adjacent secondary forest; it was never seen in primary forest. On September 4, 1962, I saw 10 to 15 in the cocoa, moving in a loose flock. The birds uttered call notes and at the same time bowed their heads sharply, as if to emphasize the call. Frequent supplanting, attacks, and other aggressive interactions were seen. The species was heard and observed also at a place 12 miles north of Kalabakan, at the edge of, but never in, primary forest.
Eurylaimus javanicus brookei Robinson and Kloss: Banded Broadbill.—Specimen, 1: Cocoa Research Station: ♂ testis 7 × 4 mm., 81.8 gm., July 25, 1962, MCT 2660.
This broadbill was seen only on two occasions at the Cocoa Research Station, both times at the edge of the primary forest.
Pitta baudi Muller and Schlegel: Blue-headed Pitta.—Specimens, 6: 12 mi. N Kalabakan: ♀, October 17, 1962, MCT 3067; ♀, October 23, 1962, MCT 3131; ♂, October 30, 1962, MCT 3182; ♀, October 30, 1962, MCT 3185; ♀, November 5, 1962, MCT 3212; ♂ testis 4 × 3 mm., November 6, 1962, MCT 3213.
The Blue-headed Pitta was abundant at the Kalabakan collecting locality, in primary forest. It was seen only once at the Cocoa Research Station.
The voice of this bird was a one-note whistle with a terminal inflection. It reminded me of a small child crying. When one called, it was usually in chorus with several others.
Pitta guajana schwaneri Bonaparte: Banded Pitta.—Specimens, 4: Cocoa Research Station: ♀ imm, 63.4 gm., July 24, 1962, MCT 2651; ♂ testis 6 × 3 mm., 81.5 gm., August 4, 1962, MCT 2723; ♀ imm., 71.8 gm., August 4, 1962, MCT 2724; ♂, June 15, 1963, ADG 145.
