Streptopelia bitorquata (Temminck): Javanese Turtle Dove.—On Siamil Island on September 18 and 19, two were seen at close range feeding with 10 S. chinensis. There is only one other record from Borneo; Pryer took one at Sandakan in the 1880's (Everett, 1889:193) and it has not been recorded since. Chasen (1935:22) speculated that the Javanese Turtle Dove was introduced to Borneo as a cage bird. But, Borneo is seemingly well within the normal range of the species and probably it is a resident of North Borneo. The Javanese Turtle Dove and the Spotted-necked Dove, S. chinensis, closely resemble each other; this resemblance may help to account for the lack of records of S. bitorquata.
Streptopelia chinensis (Scopoli): Spotted-necked Dove.—Specimens, 2: Tiger Estate: ♂, June 19, 1963, ADG 149. Telipok: ♂, February 10, 1963, TM 34.
This is a common bird of the coconut groves around Tawau and on Siamil Island.
Chalcophaps indica (Linnaeus): Emerald Dove.—Specimen, 1: Cocoa Research Station: ♂, June 17, 1963, ADG 146.
Birds, always solitary, of this species often were seen in the cocoa groves at the Cocoa Research Station.
Tanygnathus lucionensis lucionensis (Linnaeus): Blue-naped Parrot.—Specimens, 3: Siamil Island: ♂, September 19, 1962, MCT 2928; ♀, September 19, 1962, MCT 2929; ♀, September 19, 1962, MCT 2930.
These birds were seen on September 18 and 19. I saw flocks of 10 to 20 in the remnant of forest on the north side of the island. The birds were almost entirely inhabitants of the forest and were rarely seen in the coconut groves. I estimated the entire island population to be between 30 and 100 birds. The Japanese residents knew nothing of the birds, although they were aware of a cockatoo (Cacatua galerita) that had lived at large on the island for several years. The Blue-naped Parrot has been found only on the Maratuas and on Mantanani Island. Smythies (1960:242) surmised that the Mantanani population was introduced by sailing craft from the Sulu Sea. In the light of the present discovery, I think the species is a naturally-established resident of the North Bornean islands.
Psittinus cyanurus cyanurus (Forester): Little Malay Parrot.—Specimens, 2: Tiger Estate: ♀, October 11, 1962, MCT 2998; ♂, October 11, 1962, MCT 2997.
Smythies (1963:277) was the first to record this species from North Borneo. However, the Harvard Primate Expedition in 1938 took three specimens as follows: ♂, Sandakan, June 6, 1937, MCZ 197123; ♂, Morutai Besar, June 27, 1937, MCZ 197124; ♂, Kalabakan River, July 16, 1937, MCZ 197125. The Harvard collection of birds from North Borneo appears to have been overlooked, although it was mentioned in passing by Smythies (1960:526). The specimens in my collection were taken in the same general area where H. G. Deignan took the Harvard specimens.
Loriculus galgulus (Linnaeus): Malay Lorikeet.—Specimen, 1: Cocoa Research Station: ♀, May 1, 1963, ADG 103.
