Sikkim wedge-billed babbler
|Sikkim wedge-billed babbler|
Heterorhynchus humei protonym
It is found in the Indian subcontinent and nearby parts of Southeast Asia. Its range includes Bhutan, India, Myanmar, and Nepal. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is becoming rare due to habitat loss.
This species described by Louis Mandelli based on specimens from Sikkim and placed in the genus Heterorhynchus which was however preoccupied leading to it briefly being placed in the genus Stachyrirhynchus by Hume. However the genus Sphenocichla was erected before this by Godwin-Austen and Lord Tweeddale for the Manipur or Cachar wedge-billed babbler and this species was moved to the genus Sphenocichla.
The species was previously known as the wedge-billed babbler and included Sphenocichla humei and the now separated Sphenocichla roberti which was earlier treated as a subspecies.
It inhabits the understorey of broadleaf evergreen forest and bamboo at 900-1,950 m, favouring westward facing slopes in Bhutan. It occupies lower elevations only during the winter. It occurs in small parties and feeds on insects, particularly woodlice and boring beetles.
