Black-throated Tit
Aegithalos concinnus
Boldly patterned, tiny bird, usually found in groups. Adult gray above, pale below, with yellow eye and black throat and mask separated by white, chestnut-washed flanks. Juvenile has gray rather than orange and lacks black on throat. Significant regional variation in exact facial patterning: Indochinese population birds have a gray crown (bright rufous in other populations) and Himalayan birds have an white oval brow patch. Forages acrobatically in small branches, sometimes hovering at the tips to extract invertebrates. Often difficult to see in dense trees; presence given away by high-pitched contact calls (“tsip”) and thin, rolling trills. Predominantly found in broadleaf and mixed forests in foothills and submontane areas, but can also range into lowlands.
识别特征
The black-throated bushtit is a small passerine, around 10.5 cm long and weighing 4-9 g. There is considerable racial variation in the plumage, but all subspecies have a medium length tail (as opposed to the long tail of the related long-tailed tit), a black throat and a black 'bandit mask' around the eye. The nominate race has a chestnut cap, breast band and flanks and dark grey back, wings and tail, and a white belly. The other subspecies have generally the same pattern (minus the chest band) but with grey caps or all grey bellies and flanks. Both sexes are alike.
分类信息
The species has six currently recognised subspecies, and several others have been suggested. Genetic studies have suggested that these subspecies may represent separate species, but further research is needed.

行为
The black-throated bushtit is highly social and will travel in large flocks of up to 40 birds.<p>The nest is constructed out of moss and lichen and hangs from the branches of trees.<p>The species feeds on small insects and spiders, as well as small seeds, fruits and berries (particularly raspberries). Group numbers swell during the non-breeding season, but smaller groups exist year round. These groups will often join mixed-species feeding flocks.

Sakesphoroides cristatus
Striking crested antshrike. Males are black from the crest to the breast, with a spotted white-tipped tail; females have a rusty crown and an all-brown tail.
