Birds of Celebes: Treronidae. 
bill and a little longer wing, the head paler grey, the throat lighter and a httle more 
washed with grey, the entire breast and abdomen of a paler green, the anal region 
more white, and the under tail-coverts slightly paler. The brownish orange spot (?) 
in front of the shoulders is very much paler and occupies a larger area” (Hartert). 
Measurements. Wing 157—161 mm; tail 95—98; tarsus 20—22; bill from hind end of nostril 
to tip 16 — 17; height from angle of mandible 9 (Hartert). 
Distribution. Djampea and Kalao (Everett). 
The typical specimens of this species were obtained by Mr. Wallace in 
the Southern Peninsula of Celebes near Macassar. Specimens from the Northern 
Peninsula appear to us to differ very slightly, having the grey of the head car- 
ried a little further back on to the nape, and the back a shade darker mealy 
maroon-purple in the male, or a shade darker green in the female. Count 
Salvador! remarks that females from the Sula Islands have the edges of the 
median and greater wing- coverts and secondaries yellowish white, instead of 
white, with a slight green tinge along the very edges, but this character varies 
somewhat in Celebesian birds; as a rule the median covert edges are white, the 
others more or less entirely pale ochre-yellow. The birds from Djampea and 
Kalao seem from Mr. Hartert’s description and measurements to represent a well 
marked local race. 
The Celebes Green Dove is extremely closely related to O. sangirensis, which 
differs chiefly by its larger size and larger bill, and to O. griseicauda of Java 
(and Kangean according to Vorderman, N. T. Ned. Ind. LII 1893, 202) which 
Count Salvadori, following Mr. Wallace, distinguishes chiefly by its having 
the dark band across the tail not blackish, but grey and ill-defined, and the 
size slightly smaller (wing 140 mm). 
The Green Dove is a common species according to Meyer’s observations, 
in the Minahassa, the Gorontalo district, and in South Celebes. It feeds 
on fruits, waringin (figs) and others; flies singly and very quickly, not in flocks 
or pairs. Its cry is “Koowoo, koowoo”, sad and howling; hence old folks 
say to little children who whine that they are just like this bird (b 4).
