Haliaeetus leucogaster (Gmelin): White-bellied Sea Eagle.—This eagle appears to be fairly common along the coast in the Tawau-Darvel Bay area. I saw it around Cowie Harbor, Tawau, Semporna, and Siamil Island.
Spilornis cheela Latham: Crested Serpent Eagle.—I saw this eagle but once, circling overhead at the Cocoa Research Station on September 26, 1962.
Microhierax latifrons Sharpe: White-fronted Falconet.—Specimens, 2: Cocoa Research Station: ♂ testis 2 × 1 mm., 41.2 gm., July 6, 1962, MCT 2600. Tiger Estate: ♀ oviduct regressing, old brood patch, December 1, 1962, MCT 3418.
This species was first seen at the Cocoa Research Station. The specimen taken there bobbed its head in the manner of various other falcons. On two occasions individuals were observed sitting in a low tree in the front yard of a home in Kalabakan.
These records extend the known range of this species south from Darvel Bay (Smythies, 1960:161) to Cowie Harbor.
Falco peregrinus japonensis Gmelin: Peregrine Falcon.—Specimen, 1: Kampong Kuamut: ♂, October 20, 1963, ADG 327.
Coturnix chinensis (Linnaeus): Painted Quail.—Specimen, 1: Cocoa Research Station: ♂ testis 8 × 5 mm., September 6, 1962, MCT 2881.
This specimen is intermediate between C. c. lineata and C. c. caerulescens, tending slightly toward the latter in having more rufous coloring on the tertials. R. E. Kuntz took a male at Ranau (USNM 472504) that was also intermediate in its characters but was referable to C. c. lineata. These two specimens, when compared with series of specimens from the Philippines and Sumatra, fitted into a clinal progression of increasingly rufous tertials toward Sumatra. Peters (1934:96) united C. c. caerulescens with C. c. palmeri, but Amadon (in litt.) retains C. c. caerulescens (Smythies, 1957:588). No clear-cut distributional pattern is yet discernible in North Borneo and the arrangement of Amadon (MS) should probably be reviewed again when more specimens become available.
These birds were observed several times at the Cocoa Research Station but were difficult to collect. They were abundant in the grasslands on the Brantian Estate.
Rollulus roulroul (Scopoli): Crested Green Wood Partridge.—It was observed once along the Apas River at the Cocoa Research Station, in primary forest.
Haematortyx sanguiniceps Sharpe: Crimson-headed Wood Partridge.—Frederick Dunn saw one fly across the padang at the Cocoa Research Station rest house on September 9.
Lophura ignita (Shaw and Nodder): Crested Fireback Pheasant.—Specimens, 3: Cocoa Research Station: ♀, molting, July 20, 1962, MCT 2624. 12 mi. N Kalabakan: ♀, November 4, 1962, MCT 3206; ♂, November 7, 1962, MCT 3216.
