Striated Bulbul
Alcurus striatus
纵纹绿鹎
Introduction
The white-throated bulbul (Alcurus striatus) is the sole species within genus Alcurus, belonging to family Pycnonotidae. It occurs across the eastern Himalayan foothills and northern Indochina, inhabiting subtropical and tropical moist montane forests at elevations ranging from approximately 1,200 to 2,800 meters. This species forages actively through forest canopy and mid-story layers. Three recognized subspecies exhibit slight geographic variation in plumage. The species has a local and patchy distribution throughout its range.
Distribution & Habitat
The species ranges from the eastern Himalayas through northeastern India, southern China, and western Myanmar southward into northern Indochina, including eastern Myanmar, northern Thailand, Laos, and northern Vietnam. The three subspecies show a sequential geographic arrangement: the nominate subspecies occupies the core range from the eastern Himalayas through northeastern India and western Myanmar into southern China; A. s. arctus is restricted to the Mishmi Hills in northeastern India; and A. s. paulus extends through eastern Myanmar and southern China into northern Indochina. This bulbul exclusively inhabits subtropical or tropical moist montane forests, where it remains year-round without documented migratory movements.
Conservation
The species is currently evaluated as Least Concern by the IUCN Red List, indicating that it does not face immediate significant threats at a population level. However, like many montane forest specialists, it may face ongoing pressure from habitat loss and degradation across its range. The montane forest habitats it occupies are generally more resilient to some forms of disturbance than lowland forests, but continued monitoring remains advisable as development pressures increase in Himalayan and Indochinese mountain regions.
