water. No. 4446 was caught in a dead-fall trap set near a 
stream in the forest, as described under Pteronetta hartlauhi . 
No. 4359, a breeding male, was shot by Nkolo “on its 
nest/ 5 about 3 o’clock in the afternoon, in a bit of forest 
near a stream between two villages. The nest, which was 
brought to me with a single egg, was more of a structure than 
Doves usually make. The base was composed of sticks, some 
as large as a pencil, and on top were tendrils. The egg is 
cream-coloured, glossy, and measures 27 X 22 mm.

I cannot account for the difference in colour between the 
metallic wing-spots of different individuals. It does not 
seem due to age or sex, neither does it seem to indicate 
that the birds belong to two different species. 
This species has twelve rectrices, and the wing is eutaxic. 
Though many specimens of this Dove have been killed— 
mostly caught in snares in the forest—and I have sometimes 
seen it alive, generally on the ground, it is only lately that 
I have witnessed it uttering its call-notes, so as to know 
certainly what sound it makes. The notes I saw and heard 
it uttering were not distinguishable from those of a Tiympan- 
istria , and differed from those of Chalcopelia afra (see below) 
only in being stronger and fuller in tone. These three 
Doves have the same name in Bulu, doubtless because their 
call-notes are so nearly alike. The name u Odu 55 is not 
imitative, but rather derived from the word “ du” which 
means “ crying 55 or “mourning.” 
The only nest that I have seen was brought to me along 
with the female (No. 4499) and two nestlings. This nest 
consisted of a bed of decaying stems and leaves, with some 
rootlets on the top, and was not so scanty as the nests of 
most other Doves. It was found on the horizontal limb of 
a tree, near the ground, in the forest.
