识别特征
The Namaqua dove is a tiny sparrow-sized pigeon, typically 22 cm in length with a 28–33 cm wingspan, and weighing 40g. It has a very long black tapered tail, and the size and shape have led to comparison with the budgerigar. The plumage is mostly grey apart from a white belly, and chestnut primary feathers which are visible in flight.<p>The adult male has a yellow and red beak and a black face, throat and breast. The adult female lacks the black and has a red-based grey bill. Young birds are dark blotched on the wings and shoulders, and otherwise resemble the females.<p>The song is a quiet, short, double hoo, higher on the longer second note kuh-whooo, mournful and frequently repeated.
分类信息
The Namaqua dove is the only species in the monotypic genus Oena. It is most closely related to doves in the genus Turtur, and some phylogenetic evidence suggests that Oena may be a part of Turtur.<p>In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Namaqua dove in his six volume Ornithologie based on a specimen collected near the Cape of Good Hope in South Africa. He used the French name La tourterelle du Cap de Bonne Espérance and the Latin Turtur capitis bonae spei. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the Namaqua dove which he placed with the other pigeons in the genus Columba. Linnaeus included a brief description, coined the binomial name Columba capensis and cited Brisson's work. The specific name capensis denotes the Cape of Good Hope.<p>The Namaqua dove is placed in its own genus Oena that was introduced by the English naturalist William John Swainson in 1837. The genus name is from the Ancient Greek oinas meaning "pigeon". Alternative names for the Namaqua dove include Cape dove and long-tailed dove.<p>Two subspecies are recognised:

行为
The dove is quite terrestrial, and usually forages on open ground and roadsides. The food is almost exclusively minute seeds, such as those of grasses, sedges and weeds. It is not gregarious, being encountered singly or in pairs, though they may form larger flocks at waterholes. The flight is fast with clipped beats and a tendency to stay low.<p>It builds a stick nest in a bush.<p>It lays two white eggs, which are incubated for 16 days in typical pigeon fashion; the female at night and early morning and the male from mid morning till late afternoon.
