Marshall's iora (Aegithina nigrolutea), also known as the white-tailed iora, is a songbird in the genus Aegithina found in parts of India and Sri Lanka. The status of the species has been debated, and has only since 2003 returned to widespread acceptance at its original rank as a full species. 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.

Rare
Under 5% of wildlife watchers report a White-tailed Iora sighting in Ranthambore National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 233rd most-seen of the 251 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a White-tailed Iora in Ranthambore National Park on a given day, against under 5% in August to June, the lowest months. That is one of Ranthambore National Park's wettest months, with about 250 mm of rain against 5 mm in February.
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.
3rd of 3
Of the 3 parks where we can rate White-tailed Iora sightings, Ranthambore National Park ranks 3rd at under 5%. The best odds are in Udawalawe National Park (Sri Lanka, about 40%) and Yala National Park (Sri Lanka, about 10%).
GBIF citizen-science records
It is estimated from how often the White-tailed Iora is recorded against all the birds logged in Ranthambore National Park (8 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.
