428 Mr. B. Alexander —An Ornithological 
observing at least one or two individuals of this species. It 
is not at all shy, and resembles the Green Woodpecker in its 
alarm-note and flight. When the first rain was experienced 
(Nov. 20), being rapidly followed by a general bursting out 
of leaf, a remarkable increase in the numbers of these birds 
took place. They were full of activity, the sound of their 
drilling taps against the hollow branches disturbing the great 
silence of the woods. 
We procured a good series. In some specimens the iris 
was hazel, in others red. A female (by dissection) obtained 
on Dec. 26 has some of the feathers of the crown tipped 
with scarlet. 
175. Turtur semitorquatus (Rupp.). 
Common in suitable localities where there are extensive 
stretches of waste land near the river. 
We often found this Pigeon in company with T. damarensis. 
176. Turtur damarensis Finsch & Hartl. 
Common. 
177. Turtur senegalensis (Linn.). 
Fairly plentiful, and found chiefly frequenting marpela- 
fields near the native villages. The coo of this Dove is very 
loud, and might be described by the syllables “ kuk-kuk- 
koo.” 
Adult A (Chicowa). Iris black ; legs and feet claret-red. 
Adult $ (Tete). Iris hazel; legs and feet purplish-red. 
178. Chalcopelia afra (Linn.). 
Ubiquitous. 
179. CEna capensis (Linn.). 
Of local distribution, but fairly numerous in suitable 
localities, especially on waste land near the river. 
The vicinity of water is essential to this species. Breeds 
in September. 
The note of the male is soft and musical, and might be 
rendered by the syllables “ tui-tui-teu,” constantly repeated. 
Adult A (Chicowa). Total length (measured in the flesh)
