Earlier suggestions have been that it was a clinal variant of the common iora Aegithina tiphia.
The diagnostic features of the species are the short wing and tail; white edging to tertials converging broadly at the tip, versus tertial tips black to only narrowly white in A. tiphia and a smaller and shorter bill than A. tiphia from any part of India. The vocalizations are also different. The species is best known from northwestern India, however a few verified specimen records exist from southern India. It is now also known from Sri Lanka.
There are some races of the common iora that may appear similar to this species: Specimens showing nigrolutea characters collected within the range of Aegithina tiphia may be variants of the latter; such specimens have been obtained from southern Bihar, West Bengal, Khandesh, Tamil Nadu and Mysore.

Likely
About 40% of wildlife watchers report a White-tailed Iora sighting in Udawalawe National Park on a given day, based on 197 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 43rd most-seen of the 166 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 60% of wildlife watchers report a White-tailed Iora in Udawalawe National Park on a given day, against about 20% in September, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-tailed Iora sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate White-tailed Iora sightings, Udawalawe National Park has the highest daily chance: about 40%. Next come Yala National Park (Sri Lanka, about 10%) and Ranthambore National Park (India, under 5%).
GBIF citizen-science records
It is estimated from how often the White-tailed Iora is recorded against all the birds logged in Udawalawe National Park (197 verified sightings from 2019 to 2026), 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.
