The Black-breasted Parrotbill, known scientifically as Paradoxornis flavirostris, is a distinctive bird with a robust stature, measuring 19 cm in length. It is characterized by its large, thick bill and the striking black patches adorning the sides of its head and throat.
Upon observing this bird, one will note the overall brown plumage, contrasted by an extensive black area on the upper breast. The underparts are a uniform rufous-buff, providing a warm tone to the bird's appearance.
This species is known to inhabit the plains and foothills, finding solace in the lush landscapes of the Brahmaputra valley.
Endemic to the Indian subcontinent, the Black-breasted Parrotbill is primarily found within the territories of Arunachal Pradesh and Assam in India. Historical records suggest its presence in Bangladesh and possibly eastern Nepal, though such sightings are now rare.
The Black-breasted Parrotbill is a bird that once enjoyed a fairly widespread and locally common status. However, recent observations have been limited to three disjunct locations, indicating a change in its prevalence and possibly its behavior.
The vocal repertoire of this bird includes a gruff 'howh', 'jeehw', or 'jahw'. Its song is a rhythmic series of 'aw jahw jahw jahw' and 'uhwi uhwi uhwi uhwi'. In moments of heightened expression, it may deliver a higher-pitched 'wi chi'chi'chi'chi'chi', 'wi yi'yi'yi'yi'yi', and 'wi'uwi-uwi-uwi wi chu-chu-chu'.
The Spot-breasted Parrotbill is a close relative and can be distinguished by its arrow-shaped spotting on the breast and pale buff underparts, in contrast to the uniform rufous-buff of the Black-breasted Parrotbill.
The IUCN Red List has classified the Black-breasted Parrotbill as Vulnerable, indicating that this species faces a high risk of endangerment in the wild.
