||31-35 cm. Medium-sized, forest-dwelling bird. Generally dark purple with wings, rump and belly deeper blue and conspicuous silvery-blue circle on primaries. Bright red bill, legs and bare orbital ring. Similar spp. Common Dollarbird E. orientalis is smaller with brownish head and mantle, greenish-blue wings and underparts. Voice Undocumented, but probably a staccato chattering like other members of the genus.

This species is classified as Near Threatened because it has a small population which is suspected to be suffering continuing declines as a result of habitat loss and degradation in its moderately small range. Its status is very poorly known, but it has previously been downlisted from Vulnerable owing to a lack of quantitative data to confirm the suspected decline in its population.
|Previously published Red List assessments:|
- 2016 – Near Threatened (NT)
- 2012 – Near Threatened (NT)
- 2008 – Near Threatened (NT)
- 2007 – Near Threatened (NT)
- 2004 – Vulnerable (VU)
- 2000 – Vulnerable (VU)
- 1994 – Lower Risk/least concern (LR/lc)
- 1988 – Lower Risk/least concern (LR/lc)
|Population:||The population is estimated to number 2,500-9,999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.|
Trend Justification: Moderate declines are suspected to be occurring, owing to on-going and rapid rates of habitat loss in the lowlands throughout the species's range.
