Notice the odd flap over the nostril which is peculiar to this genus. It forages by digging in the ground with its long powerful bill. This species has a limited range in the foothills with isolated populations in SE Asia. HBW and IOC place this bird in the genus Pomatorhinus while H&M places it in Erythrogenys. Some authors lump this species with the Black-necklaced, Spot-breasted, Black-streaked, and Gray-sided Scimitar-Babblers. Others (e.g. H&M) split the Rusty-cheeked, but lump the other four under the name Spot-breasted. The current Clements/eBird classification is based on new genetic evidence (Moyle et al. 2012). The use of the genus Megapomatorhinus is also new with their study. Four or five subspecies recognized. This is the nominate race with a white throat. Gray-throated forms are found farther east.
