Namaqua Dove
Oena capensis
Tiny, long-tailed dove that is dark above and pale below. Male has a black mask and colorful bill. Female has a plain head and dark bill. In flight, the wings are bright rufous. Found in a variety of dry, open habitats at low and middle elevations. Voice is a long, two-parted “hoo-oooooo” which is repeated, sometimes endlessly. Distinguished from all other doves in its range by its small size and long-tailed shape.
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:

Gray-crowned Palm-Tanager
Phaenicophilus poliocephalus
A woodland species that also ventures into parks and gardens. Often found in groups of up to five foraging at middle to upper heights and uncommonly joins mixed-species flocks. Note this species’ black cheek, which is bordered below by broad white moustache stripes and above by a gray crown. The similar Black-crowned Palm-Tanager has an entirely white throat and a black crown. Vocalizations are poorly known, but include a high thin “tseeoo” that is briefer than similar note of Black-crowned.
Siberian Jay
Perisoreus infaustus
A charismatic inhabitant of northern coniferous forests, especially old growth lichen-rich ones. Dusky-brown and gray body with cinnamon on sides of tail, rump and on patches of the upper wing. Usually quiet. Feeds on seeds, berries, carrion, small insects also takes eggs and young of small birds. Often accepts food handouts from humans and can be quite tame.
Brambling
Fringilla montifringilla
Distinctive and handsome orange-breasted finch. Note black head of males (solid in breeding season, patchy in non-breeding) and gray-and-brown head of females. Complex wing patterns and white rump patches create a wondrous show when a flock rises up in flight. Breeds in northern woodlands, especially in and around birches; winters in varied wooded habitats (especially with beech trees), semiopen country, and farmland with hedges; sometimes visits gardens and parks with feeders or fruiting trees. Song is surprising and almost ugly for such a well-marked finch, a strange ringing buzz: “eerRRRRNnnn.” Gives a rising “qweee”, a higher-pitchd “tsi, tsi”, and various twittering and nasal flock calls.
