Taxonomic note
Elaphrornis palliseri (del Hoyo and Collar 2016) was previously listed as Bradypterus palliseri; appears to be closely related to that genus, but differs in structure (relatively shorter-tailed and longer-billed), plumage (unmarked) and song. Placement in separate genus confirmed by molecular analysis of Alström et al. (2018). Monotypic.

Population justification: The global population size has not been quantified, but the species is described as locally not uncommon (del Hoyo et al. 2006). It is mostly abundant in montane forests. A survey across the Sri Lankan wet and montane zones detected the species approximately 169 times during 2007-2009 (E. Goodale in litt. 2020).

Trend justification: Slight declines are thought likely to be occurring as a result of habitat loss within the lower elevational range of this species.
