Rufous-necked Laughingthrush
Pterorhinus ruficollis
This laughingthrush’s color palette is simple but smooth and unique: dark gray overall with a black face and pumpkin-orange neck and vent. Favors forest edge and scrubby habitat more than most other laughingthrushes in its range; also often found along rivers and in reedbeds. Forages on or near the ground; flocks in the non-breeding season. Gives loud whistles and burbling phrases, as well as harsh chattering and rasping notes.
识别特征
The rufous-necked laughingthrush is actually not a thrush but a species of babbler, it is roughly 22–27 centimetres (8.7–10.6 in) in length and weighs anywhere between 51–73 grams (1.8–2.6 oz). The rufous-necked laughingthrush as its name implies has a rustic color around its neck. overall the bird is grey with a black face and its rufous neck. Due to the fact that they are non migratory birds this means that they molt very slowly which means that they look the same as young birds than as older birds. The rufous-necked laughingthrush looks very similar to a rufous-cheeked laughingthrush yet the regions where both species are found are completely different.
分类信息
The rufous-necked laughingthrush was placed in the genus Dryonastes before being moved to Garrulax. Following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved again to the resurrected genus Pterorhinus.

分布与栖息地
The rufous-necked laughingthrush is found in the subtropical or tropical moist forests from Nepal to China extending down into Myanmar. It is a non migratory songbird which means it spends its entire life in the same location or habitat for both reproductive and non reproductive periods. Some populations are found in isolated regions of Nepal likely something that happened during the formation of the mountain ranges in the region. The species is commonly found in all of its native ranges and is considered of least concern by the IUCN redlist.

行为
The vocalization of this laughingthrush is a series of small chirps that ramble in out of order note calls which resemble mocking bird calls that simulate some babbling or laughing as the name describes. Its quick whip calls are easily recognizable especially in larger flocks of feeding groups.<p>Rufous-necked laughingthrush generally feed on insects but have generalist bills and can feed on seeds molluscs and berries as well. Due to this generalist feeding behavior food sources are not as difficult to come by for these laughingthrushes as they are for specialists.<p>Rufous-necked laughing thrush have not been studied for their reproduction but it is assumed that they reproduce similarly to other laughing thrushes. Their intelligence makes it difficult for parasitic reproducers like cuckoos to take advantage of them. Their egg recognition is very good and therefore can remove intrusive eggs that don't resemble theirs at all. In terms of mating rufous-necked laughingthrushes tend to are sexually dimorphic in size and it may be linked to the female choice of individuals with the best territorial defense and therefore size was probably selected over time. They breed from March to August, creating small cup nests that are compact and made of leaves and grasses.

Magpie Mannikin
Spermestes fringilloides
Large waxbill with a big bill. Shows a black head, brown back, and black scallops along the sides of the breast. Found in bamboo, moist scrub, moist cultivation, lush savanna, and forest edge. Quite scarce across most of its range. Call is a descending “teeiw”. Superficially similar to Bronze Mannikin but larger and bigger-billed, with an all-black head and distinctive scallops along the breast sides.
Moustached Warbler
Acrocephalus melanopogon
Resembles Sedge Warbler, but larger with a thick and well-marked white eyebrow and throat; contrasting dark cap; rufous rump, nape, and sides; short wings; and dark legs (pale in Sedge). Found in dense reed beds, often with bulrush stands. Makes muffled "treck" calls recalling a stonechat. Scratchy, repetitive song is given from the upper half of a plant stalk; does not sing in flight.
Chestnut-winged Foliage-gleaner
Dendroma erythroptera
Gray-brown foliage-gleaner with reddish wings and tail. Face and throat washed with dull yellow, with a faint eyeline; this is unlike many other foliage-gleaners which have a clear eyebrow or throat patch. Usually forages fairly high in the midstory and canopy of mature rainforest, often with mixed species flocks. Many foliage-gleaners have reddish wings; look for reddish wings contrasting with grayish body and tawny ochraceous face and throat in this species.
