Rufous-bellied Niltava
Niltava sundara
As in other niltavas, the male is brilliantly colored while the female is drab brown overall. Male bright blue with an orange belly; female is brown with a white throat strap and a small blue crescent on the neck. Female is very similar to other niltavas, intermediate in size between Little and Large niltavas, with stronger warm tones on the wings and tail than Fujian Niltava. Active in the middle and upper layers of broadleaf and mixed hill forests, where it often associates with other species in mixed flocks. Gives a series of high, piercing metallic whistles.
分类信息
The rufous-breasted niltava is one of six species in the genus Niltava, found in South and Southeast Asia as well as in China. This bird has sometimes been considered to be conspecific with the Fujian niltava and rufous-vented niltava.<p>It was described by the English naturalist Brian Hodgson in 1837. The specific epithet sundara is a Latinised version of the Hindi word sundar, meaning "beautiful".<p>The bird has also been called the blue-and-orange niltava or black-and-orange niltava, as the male's blue upperparts may look black in poor light. Other names for the bird include orange-bellied niltava, beautiful niltava, or the sundara niltava.<p>N. s. sundara - (Hodgson, 1837): The nominate subspecies, it is found in the central and eastern Himalayas east from Nepal and from South China to Myanmar. Non-breeding individuals are also found northeastern Bangladesh.<p>N. s. whistleri - (Ticehurst, 1926): Found in the Himalayas in north India and Pakistan, extending eastward up until Uttarakhand. The subspecific epithet is in honour of Hugh Whistler. Males have paler underparts than that of the nominate, and females have a paler tail, upperparts, and more greyish-olive on their underparts.<p>N. s. denotata - (Bangs & Phillips, 1914): Found in eastern Myanmar, southern China, and northwestern Vietnam. Non-breeding individuals can be found further south to northern Thailand and Indochina. Males more violet-blue in colour than that of the nominate, with females having more olive-brown on the crown and nape, buff on forehead, rufous-brown on mantle and rufous on uppertail-coverts and tail edges.

行为
The rufous-breasted niltava is predominantly insectivorous. Its diet mainly consists of small invertebrates and larvae (especially ants and beetles), along with occasional consumption of fruit. Feeds by perching quietly in the undergrowth and darting out or dropping to the ground to catch prey. Rufous-breasted niltavas tend to feed either solitarily or in pairs, sometimes joining mixed-species flocks. It tends to be more solitary in winter.

Chestnut Wood-Quail
Odontophorus hyperythrus
This chickenlike bird is bright rufous on the face and underparts and brown above. Female similar to male but rufous more restricted to the upper breast with contrasting gray belly. Also note slight crest, stout bill, and some bare gray skin around the eye. Uncommon in cloud forest of western Colombia. Shy and difficult to see; stays in small groups on the forest floor and rarely comes out in the open. Listen for rollicking whistled song, similar to other wood-quail.
Somali Grosbeak
Rhynchostruthus louisae
Handsome chunky gray-brown finch with a massive dark bill, dark-brown cap, and blackish face mask extending to the throat. Female has a paler forehead and crown. Juvenile is streaky with a more diffuse mask. Ecology is poorly known but presumed to be similar to that of Arabian Grosbeak, with pairs and small groups frequenting thorn-scrub and riverine vegetation up to 1400m in the northern Somali mountains, where it is a scarce endemic. Vocalizations largely unknown, but presumed to be similar to those of Arabian Grosbeak. In addition to range, other “golden-winged” grosbeaks differ from Somali in having pale ear-patches.
Yellow-green Brushfinch
Atlapetes luteoviridis
Hefty, long-tailed finch with a very limited range in western Panama. Its olive-greenish body with contrasting black head and bright yellow tufts at the base of each leg make this bird distinctive. Poorly known, but behavior apparently similar to Yellow-thighed Finch (no range overlap); found close to the ground, working through low tangles and bushes in pairs or small groups. Sometimes ventures up into the middle levels. Prefers forest and edges.
