White-browed Shrike-Babbler
Pteruthius aeralatus
A small, stout bird with a large head, usually found at mid-level in forests. Male is smartly attired: clean white below and black above with a gray back, a white eyebrow, and two bright, flame-like orange stripes towards the wingtips. Females have the same general patterning, but are much more faded, replacing black with gray and orange with yellow-green. Often joins mixed flocks in foothill and montane forests, where it can be fairly common. Song is a forceful series with slight breaks every second or third note: “dyudyu-dyu-dyudyu!”
识别特征
The white-browed shrike-babbler is sexually dimorphic. There are many variations between the populations and some are more distinctive than others but they may not be easy to diagnose in the field. In general appearance it is very similar to the Himalayan shrike-babbler but all subspecies with the exception of validirostris have the tertials of males partly coloured rufous and partly fulvous.<p>The common name commemorates Edward Blyth (1810–1873), who published the description and notes based on Samuel Tickell's specimen. It was earlier called Tickell's shrike-Tit.
分类信息
The species was described by Edward Blyth who credited the name to collector Captain Samuel Tickell. This and several other species were later lumped together as subspecies of Pteruthius flaviscapis. In 2008, a molecular phylogenetic study resulted in the separation of species within the flaviscapis group with a large number split by application of the phylogenetic species concept and these were reorganized with a smaller number of species resulting in the following subspecies being included within white-browed shrike-babbler.

Gray Antbird
Cercomacra cinerascens
Slender, long-tailed antbird of rainforest midstory. One of the most common antbirds in Amazonian rainforest, and can be found around forest edges and dense secondary growth as well as in more mature rainforest. Prefers vine tangles in the subcanopy, and can be very hard to see as they forage in dense, high vegetation. Males are gray with white wing bars; females are grayish brown with white wing bars. Both sexes have bold white spots on the underside of the tail. Its song is one of the most frequently heard sounds in Amazonia, a slow bouncing “erk, CHAT, erk, CHAT, …”
Chestnut-crested Antbird
Rhegmatorhina cristata
Striking, medium-sized antbird, brown above and rich chestnut below, with a black face and broad white bare eye-ring. Females have thin black bars above. Inhabits the understory of humid forest, where it is always found foraging at army-ant swarms. The song is a series of ascending whistles that finishes with harsh descending notes.
Rufous-tailed Stipplethroat
Epinecrophylla erythrura
Brown antwren with reddish tail and wings. Head is gray in both sexes, fading into a warmer brown lower body. Cream wingbars. Slightly longer tailed than similar antwrens and typically forages higher in the midstory. Often joins mixed-species flocks with other antwrens and antshrikes. Listen for its song: a steady series of high, rising “pseet” notes.
