The Red-backed flameback, Lesser Sri Lanka flameback, Sri Lanka red-backed woodpecker or Ceylon red-backed woodpecker (Dinopium psarodes) is a species of bird in the family Picidae. It is endemic to Sri Lanka, only absent in the far-north. It is sometimes considered a subspecies of the Black-rumped flameback.
It has been considered an endemic species since the time of Legge. It was first placed in the genus Brachypternus as Brachypternus ceylonus. It was later lumped as subspecies of the Black-rumped flameback (Dinopium benghalense), as Dinopium benghalense psarodes. It was elevated to full species status in a study by Sampath S. Seneviratne, Darren E. Irwin, and Saminda P. Fernando.
In this study, it was found to hybridize with the Black-rumped flameback. The hybridization is concentrated north of a border from Trincomalee to the base of Puttalam lagoon and south of a border from Mullaitivu to Mannar. Hybridization is less out of this border, where the Black-rumped flameback dominates north of the border while the Red-backed flameback dominates south of the border. It is a case of Hybrid inferiority, in which the pure species are more successful than the hybrids... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Lesser Sri Lanka Flameback is recorded against all the birds logged in Colombo [Sri Jayawardenepura Kotte] (2,482 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
