The greenish warbler (Phylloscopus trochiloides) is a widespread leaf warbler with a breeding range in northeastern Europe, and temperate to subtropical continental Asia. This warbler is strongly migratory and winters in India. It is not uncommon as a spring or early autumn vagrant in Western Europe and is annually seen in Great Britain. In Central Europe large numbers of vagrant birds are encountered in some years; some of these may stay to breed, as a handful of pairs does each year in Germany.
Like all leaf warblers, it was formerly placed in the "Old World warbler" assemblage, but now belongs to the new leaf-warbler family Phylloscopidae. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific trochiloides is from Ancient Greek trokhalos, "bowed", and -oides "resembling", from the similarity to the willow warbler, P. trochilus. The English name of this species provides a perfect argument in favour of the capitalisation of species names (i.e. treating them as proper nouns), a convention which is generally applied in scientific literature. The decapitalised "greenish warbler" is equally descriptive of many bird species across multiple families, whereas a capitalised "Greenish Warbler" shows unambiguously that Phylloscopus trochiloides is under discussion.

Possible
About 20% of wildlife watchers report a Greenish Warbler sighting in Bhubaneshwar on a given day, based on 276 verified sightings from GBIF citizen-science data. It is the 38th most-seen of the 148 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 50% of wildlife watchers report a Greenish Warbler in Bhubaneshwar on a given day, against under 5% in May to July, the lowest months. That is one of Bhubaneshwar's driest months, with about 10 mm of rain against 340 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Greenish Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 70
Of the 70 cities where we can rate Greenish Warbler sightings, Bhubaneshwar ranks 6th at about 20%. The best odds are in Jabalpur (India, about 40%), Raipur (India, about 30%) and Asansol (India, about 30%).
GBIF citizen-science records
It is estimated from how often the Greenish Warbler is recorded against all the birds logged in Bhubaneshwar (276 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.
