Taiwan Yuhina
Yuhina brunneiceps
A small, tit-like endemic songbird, brown above, white below, with a very distinctive head pattern: the pointed crest is white with a black-bordered chestnut front, and the ear coverts are outlined in black on the white face. Inhabits hilly and montane forests, where it roams about in large chattering flocks at all levels of the forest. Song is a simple clear series of strident whistles, sounding a bit like a wolf-whistle or a friendly sounding “to-meet-you.”
识别特征
The Taiwan yuhina is 12–13 cm (4.7–5.1 in) in length with a chocolate brown crest and a black beard stripe descending from its beak. The bird's back, wings and tail are dark ash brown, and its lower breast is lighter in colour. Agreeing with other typical yuhinas in habitus, its colouration pattern makes it rather distinctive among the genus.
分类信息
Like other yuhinas, it is closely related to the white-eyes and if these were considered a distinct family Zosteropidae, it would be placed there. Otherwise, it would be classed with the white-eyes in the Old World babbler Timaliidae family. The closest living relative of this species appears to be the black-chinned yuhina, which occurs on the Asian mainland.<p>

分布与栖息地
This species is found in hill forests at elevations of 1,000–3,200 m (3,300–10,500 ft) above sea level, although it is most common between 1,500–2,500 m (4,900–8,200 ft); it can descend to lower altitudes in winter. It is gregarious, active and quite tame. It keeps to lower forest and often joins other species, especially tits in mixed flocks. The flocks, while feeding, make a constant soft chatter. The call of the Taiwan yuhina is a sound somewhat like twi-MI-chiu, which resembles the phrase "We MEET you". The Taiwan yuhina's diet mainly consists of nectar, berries, flowers and small insects. It may sometimes be observed hanging upside down on cherry trees. These songbirds are particularly fond of the flowers of the Chinese tulip tree and the fruits of trees of the family Elaeagnaceae and the genus Idesia (Salicaceae).<p>Based on a population in Nantou County, diet during the breeding season mostly consists of nectar and fruits of Taiwan cherry (Prunus campanulata), fruits of eastern debregeasia (Debregeasia orientalis), and the nectar of mistletoe Taxillus lonicerifolius.<p>The breeding season for the Taiwan yuhina is from May to June.

Royal Parrotfinch
Erythrura cyaneovirens
A beautiful finch with a bright ocean-blue body, greenish wings, a reddish tail, a red head, and a blue throat. Mostly found in closed-canopy forest and forest edge. Scarce in open habitats. Common call is a thin, high-pitched, repetitive “seep.”
Rachel's Malimbe
Malimbus racheliae
A beautiful malimbe locally distributed in Central Africa and restricted to lowland primary forest and its edges, where it is often found high above the ground in small groups or with mixed-species flocks, sometimes with other species of malimbe. Both males and females are wholly black with yellow vents and orange chests that fade to yellow at the edges. Males also have an orange crown and neck, giving them a collared appearance. Overlaps with several other species of malimbe, but distinguished by the yellow vent and orange chest with yellow edges. Calls are short, mechanical squeaks, while the song is a longer series of notes that incorporates dry rasps, similar to the songs of other weavers and malimbes. Rachel’s Malimbe appears to be particularly fond of musanga trees, also known as corkwood or umbrella trees.
Bank Swallow
Riparia riparia
Small and compact swallow, with quick flicking wingbeats. Brown above and white below, with a contrasting dark chest band. Note the relatively long, notched tail and narrow, pointed wings. Breeds in colonies; builds nest by tunneling into sandbanks. Can be seen over any open habitat including fields, marshes, and ponds, often in mixed flocks with other species of swallows. Compare with other small brownish swallows where overlaps occur in its extensive global range.
