The Orange-breasted Trogon (Harpactes oreskios) is a species of bird in the Trogonidae family. It is found in Cambodia, China, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montanes, humid, lower-to-middle elevation evergreen forests, swampy forests, open dry forests, bamboo forests, thin tree jungles, and sometimes among clumps of trees near forests.
Orange-breasted trogons generally have an olive-yellow head with feathers that are bristled and upright, chestnut upperparts, orange breast that changes to bright yellow on upper and lower portions, white bars on wing sections, and a blue bill. Males have a dull olive-yellowish head with a blue ring; rufous (reddish brown) upperparts and upper tail with paler rump (lower part of back); broad white bars on wing sections; and yellow (gray-based) upper breast with some white along the mid-line. Females have additional gray-brown on head and upperparts; pale buffy-brown rump, gray breast; and yellow lower underparts. Juveniles are similar to females, with young males having warmer brown upperparts.
