The Chestnut-breasted Partridge, Arborophila mandellii, is a bird of remarkable distinction, with a chestnut breast-band and a grey belly. This species is named in honor of the Italian naturalist Louis Mandelli.
Upon encountering this elusive bird, one may note its rufescent crown and head-sides, which set it apart from its kin. A white gorget graces its throat, and the upper breast is entirely chestnut, distinguishing it from the similar Rufous-throated Partridge, Arborophila rufogularis.
This partridge favors the eastern Himalayas' verdant realms, thriving in the dense undergrowth that blankets the forest floor.
Endemic to the eastern Himalayas north of the Brahmaputra, the Chestnut-breasted Partridge is found in the territories of Bhutan, Darjeeling, Sikkim, Arunachal Pradesh, and southeastern Tibet, at altitudes ranging from 350 to 2,500 meters.
The Chestnut-breasted Partridge is a creature of the underbrush, where it skulks and forages, ever elusive to the prying eyes of birdwatchers.
The IUCN Red List categorizes the Chestnut-breasted Partridge as Near Threatened, with an estimated population of fewer than 10,000 individuals. Its existence is imperiled by the twin threats of forest degradation and hunting. However, there is a glimmer of hope, as it is known to inhabit at least three protected areas, including Singalila National Park and Namdapha National Park.
In 2015, a significant milestone was achieved when the first photograph of this species in the wild was captured in Arunachal Pradesh, a testament to its continued, albeit precarious, presence in its natural habitat.
