English: The silver-breasted broadbill (Serilophus lunatus), a member of the Eurylaimidae family of broadbills, inhabits various regions across Southeast Asia, including China, Myanmar, Thailand, Vietnam, Laos, Malaysia, and Indonesia. While these captivating birds are vagrant visitors to India and Bangladesh, they display a polytypic nature, exhibiting variations across different subspecies.

This medium-sized avian species, measuring 16-17 cm in length and weighing between 25 to 35 grams, boasts distinct physical characteristics. The male silver-breasted broadbill features a pale rusty-colored head with ashy gray forehead, complemented by dark rusty lores and a broad black supercilium over the eye. Its rump and upper wing coverts exhibit a rich reddish-brown hue, while the flight feathers display striking blue and black patterns. The underparts of this bird are predominantly white, with a silvery breast region, and its tail, black with graduated whitish undertail feathers. The bill, adorned in silvery blue, is encircled by orange feathers at its base, while dark brown irises and grayish-yellow feet complete its striking appearance.

In contrast, the female silver-breasted broadbill sports a thin silvery band across the breast, while juveniles resemble adults with darker plumage, albeit possessing shorter tails and wings. Their distinct call, a soft "ki-uu" or "pee-uu" sound, adds to their allure amidst the forest's chorus.
