This species did not appear at Quoin Hill until August 23. The gonads of most of the adults taken from that time on appeared to be regressing from breeding condition, and several immatures were taken also, suggesting that the breeding season was over. The birds seemed to be attracted, with bulbuls, to the tree _Trema orientalis_. _=Prionichilus maculatus maculatus=_ (Temminck): Yellow-throated Flowerpecker.--_Specimen_, 1: 12 mi. N Kalabakan: [Male], October 19, 1962, MCT 3094. I observed this flowerpecker once at Quoin Hill, in much-disturbed primary forest, but was unable to secure a specimen. Twelve miles north of Kalabakan it was found in primary forest. _=Dicaeum chrysorrheum=_ Temminck: Yellow-vented Flowerpecker.--I observed one feeding about 50 feet high among epiphytic plants in the moss forest 5.5 miles north of Tenom. _=Dicaeum monticolum=_ Sharpe: Black-sided Flowerpecker.--_Specimen_, 1: 5.5 mi. SW Tenom: [Male] testis 5 x 3 mm., December 17, 1962, MCT 3449. I saw this flowerpecker once, in the moss forest above Tenom. Treatment of this species as monotypic follows the revision of Salomonsen (1961:17). _=Dicaeum cruentatum=_ (Linnaeus): Scarlet-backed Flowerpecker.--Along the seashore near Tawau this species fed in flowering trees. Males were pugnacious and persistently chased what appeared to be females. _=Dicaeum trigonostigma dayakanum=_ Chasen and Kloss: Orange-bellied Flowerpecker.--_Specimen_, 1: 5.5 mi. SW Tenom: [Male], December 23, 1962, MCT 3507. This flowerpecker was found only in the moss forest above Tenom, where it was seen numerous times feeding among the epiphytic plants. _=Zosterops everetti tahanensis=_ Ogilvie-Grant: Everett's White-eye.--_Specimens_, 9: Cocoa Research Station: [Female], August 8, 1962, MCT 2734; [Male] testis 4 x 3 mm., August 8, 1962, MCT 2735; [Female], 8.6 gm., August 11, 1962, MCT 2757; [Female], 7.8 gm., August 11, 1962, MCT 2758; [Female] imm., 7.9 gm., August 11, 1962, MCT 2759; [Female], 8.2 gm., August 11, 1962, MCT 2760; [Male], 7.8 gm., August 11, 1962, MCT 2761; [Male] imm., August 11, 1962, MCT 2762; [Male] imm., 7.8 gm., August 11, 1962, MCT 2764. At the Cocoa Research Station flocks of 20 to 40 birds were seen daily, feeding in the cocoa trees. Only once was this species seen away from the cocoa trees; this was in secondary forest where the birds were feeding in a tree about 30 feet tall. They move in flocks and are noisy. Smythies (1960:485) states that this species occurs from the Poi Range up to the lower slopes of Kinabalu. This is apparently the first record from eastern Borneo.
