The Orange-bellied Flowerpecker, known scientifically as Dicaeum trigonostigma, is a small, vibrant bird belonging to the Dicaeidae family. The male of the species is particularly striking with its slaty-blue upperparts, including the crown, nape, wings, and tail. This is contrasted by a large, triangular orange patch on the mantle. Its bill is fairly thin and short, with a slight downward curve at the tip. The upper-breast and throat are a lighter greyish blue, while the lower breast to the vent displays a gradient from fiery orange to yellow.
To identify the male Orange-bellied Flowerpecker, look for the distinctive orange patch on its back and the gradient of orange to yellow on its underside. The female, however, is more subdued in coloration, being mostly drab olive brown with a pale orange rump and yellow belly.
This species thrives in a variety of forested environments, including subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, and subtropical or tropical moist montane forest.
The Orange-bellied Flowerpecker graces a wide range of locations across Asia. Its presence has been recorded in Bangladesh, Brunei, India, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, and Thailand.
The IUCN Red List has classified the Orange-bellied Flowerpecker as Least Concern, indicating that, at present, there are no immediate threats to its population numbers that would warrant a higher level of concern.
