Egg. “An egg in my collection taken by Dr. Platen at Rurukan, Minahassa, differs in no 
way from those of our common 0. galbula” (Nehrkorn MS.). 
The Cielebesian Golden Oriole is very closely related to 0. coronatus Sw. 
of Sumatra, Java, Borneo, and to O. imularis Vord. of the Kangean Islands. 
Except that O. celebemis is not smaller than O. coronatus, Bruggemann has 
well pointed out the differences between the two forms; 1 . O. celehensis has a 
shorter bill; 2. it wants the yellow speculum formed by the tips of the pri- 
mary coverts (one of our S. Celebesian specimens shows this as in Java birds); 
3 . the two middle tail-feathers are greenish yellow in O. celehensis, black in 
O. coronatus, in both tipped with yellow; 4 . the black coronet is broader in 
the Javan form. In respect of the tail the two forms never seem to intergrade. 
The Kangean form is said to have the tail like O. coronatus, by which it may 
be distinguished from our bird. 
The South Celebesian race stands nearer to O. coronatus than does that of 
North Celebes, suggesting that Celebes was colonised from the south, or that 
there has been a recent immigration and admixture of Javan birds in the South. 
Dr. Platen says 0. celehensis almost always flies in pairs, and has a clear 
note. Its Javan relative is described by Bernstein (J. f. Orn. 1859, 270) as 
having a flute-like song like the European O. galhula L., feeding chiefly upon 
insects, occasionally fruit, and attaching its nest to the fork of an outermost 
twig in the top of a high tree.
