The yellow-browed warbler (Phylloscopus inornatus) is a leaf warbler (family Phylloscopidae) which breeds in the east Palearctic. This warbler is strongly migratory and winters mainly in tropical South Asia and South-east Asia, but also in small numbers in western Europe. Like the rest of Phylloscopidae, it was formerly included in the Old World warbler assemblage.
The two sister species differ slightly but consistently in morphology, bioacoustics, and molecular characters. Before the species was split, the names yellow-browed willow warbler and inornate warbler were used by a few authors.
The yellow-browed warbler was first described by the English zoologist Edward Blyth in 1842 and given the binomial name Regulus inornatus. The current genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific inornatus is Latin for "plain".
This is one of the smaller Old World warblers, at 9.5–11 cm long and weighing... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellow-browed Warbler sighting in Athens on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 119th most-seen of the 145 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow-browed Warbler in Athens on a given day, so our monthly data shows no clear season.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Yellow-browed Warbler sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
63rd of 69
Of the 69 cities where we can rate Yellow-browed Warbler sightings, Athens ranks 63rd at under 5%. The best odds are in Đà Nẵng (Vietnam, about 70%), Hanoi (Vietnam, about 60%) and Xiuying District (China, about 60%).
Same genus: Phylloscopus
The closest relatives of the Yellow-browed Warbler that you can see in Athens (genus Phylloscopus, Leaf Warblers) are Common Chiffchaff (about 40%) and Willow Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-browed Warbler is recorded against all the birds logged in Athens (19 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.
