22 - 26cm (¾-10¼ in). A rather large Scimitar-Babbler:

  • Broadly orange-rufous from forehead and face to flanks and vent
  • Whitish throat and belly
  • Indistinct broad greyish-white streaks from chin to breast
  • Small black malar
  • Long whitish-horn bill
  • Eye pale or red (subspecies dependent) surrounded by dark blue bare skin and white spots

Sexes similar, juveniles paler above with duller rufous parts.

Similar species

Large Scimitar-Babbler has dark eye and grey flanks. Spot-breasted Scimitar-Babbler has blackish spots on breast.

Distribution

Found from northeast Pakistan over the Himalayas to Bhutan and in eastern Burma and northwest Thailand.
Common in parts of its range.

Taxonomy

This is a polytypic species[1] consisting of 5 subspecies.

Both species, Rusty-cheeked and Spot-breasted Scimitar-Babbler are also sometimes regarded conspecific. Further study is required to solve the taxonomy of this complex.

Berryman et al [5] propose this taxon be split into two given many plumage and vocal differences between subspecies groups (the most obvious of which are different eye colours:---red and white respectively). They elevate subspecies celatua and imberbis as "Red-eyed Scimitar Babbler", E. imberbis, leaving subspecies erythrogenys, ferrugilatus and haringtoni as "Rusty-cheeked Scimitar Babbler" (strict sense).

Subspecies

  • E. e. erythrogenys: Himalayas of northeast Pakistan and northern India
  • E. e. ferrugilatus: Montane forests of Kashmir to central Nepal
  • E. e. haringtoni: Himalayas from Sikkim to Bhutan
  • E. e. imberbis: "Red-eyed Scimitar Babbler". Karenni, eastern Myanmar
  • E. e. celatua: "Red-eyed Scimitar Babbler". Shan States, eastern Myanmar, and northwestern Thailand

Other sources [1] include haringtoni in ferrugilatus.

Habitat

Thick scrub and dense undergrowth at forest edge, scrub in open pine forest, secondary growths, thickets and bush-covered hillsides. Found at 300m up to 2400m, sometimes up to 3000m.

Behaviour

Diet

Feeds on insects, larvae, seeds and berries.
Usually seen in pairs in summer and in small groups of up to 12 birds in the rest of the year. Seldom in bird-waves. Mostly seen on the ground.

Breeding

Breeding season February to Jul. The nest is a loose dome with a broad entrance. It's made of coarse grasses, dry fern, bamboo and other leaves and placed on the ground, sheltered by vegetation or rocks or in a thick bush up to 1.2m above the ground. Lays 2 - 4 eggs.

Movements

Resident species.

Vocalisation

Repeated calls given by one bird, morning time, as it moved through a large cactus plant. Background chirping by a group of Oriental White-eyes and group of White-throated Laughingthrushes are heard. One call by Himalayan Bulbul heard in the middle part of the recording.
