- Horornis flavolivaceus
12â€“13Â·5 cm (4Â¾-5Â¼ in). A medium sized bush-warbler with short, rounded wings and average tail length, perhaps the most phylloscopus like shape wise in the region.
- Yellowish olive-green upperparts
- Pale yellowish supercilium
- Narrow whitish eyering
- Dark eyestripe
- Buffish or ollive-yellow underparts, darker olive on breast and flanks (variable)
- Dark eye
- Dark horn-brown bill, pale pink base of lower mandible
- Yellow to dusky pinkish-brown legs
Sexes similar. Juveniles are similar to adults but have uniform buffish-yellow underparts.
- alexandri with olive-brown upperparts but darker olive-buff underparts than nominate and with buffish breast and flanks
- weberi with strong rufescent-brown wash above and below, longer tail and ochre-brown breastband and flanks
- intricata is similar to weberi but paler and less yellow on underparts
- obita is similar to intricata but smaller and with brighter olive upperparts, washed pale yellow underparts and rufous-ochre flanks
 Similar species
Greener (not rufous) upperpart than Yellowish-bellied Bush Warbler without rufous wingpanel and yellowish (not grey) throat and breast. Differs from Brownish-flanked Bush Warbler in yellower supercilium obvious before eye, greener upperparts having the same colour like crown and yellowish underparts tinged olive on breast and flanks.
India and China east to Vietnam and Thailand.
Common to fairly common in parts of its range.
Formerly placed in genus Cettia.
Seven subspecies are recognized:
- North-eastern India (Garo and Khasi hills of Assam)
- Northern and eastern Myanmar and south-western China (southern Shanxi, eastern Sichuan)
intricatus, and oblitus should possibly belong with Sunda Bush-Warbler instead of Aberrant Bush-Warbler, however, that change has so far not been adopted by the major checklists.
Found in bushes, tall grass clumps, ferns, dense bamboo thickets and scrub undergrowth in forest clearings and egdes of forest.
Breeds at 2400-3950 m in the Himalayas, up to 2900m in northeastern Indian hills and between 1200 m and 4900 m in China. At lower elevations in non-breeding season.
A shy and secretive species, often skulking for long periods in thick vegetation.
Has a distinctive habit of continually flicking wings and giving grating call when alarmed. Tail often slightly raised.
Not well known, feeds probably on invertebrates and larvae.
Forages low in dense vegetation.
Poorly known. Breeding season from May to August. The nest is a ball made of dry grass, bamboo leaves and feathers. It's placed on the ground or low down in a clump of tall grass. Lays 3 to 4 eggs.
An altitudinal migrant, moves to lower elevations after breeding.
