The white-browed shrike-babbler (Pteruthius aeralatus) is a bird species found in the eastern Himalayas and Southeast Asia from northern Burma to southern Cambodia. Like others in the genus it is found in montane forests. Males and females have different plumages and variations occur through its range with several populations being treated as subspecies. It is part of a cryptic species complex and was earlier lumped as a subspecies of the white-browed shrike-babbler. Clements lumps this bird into the white-browed shrike-babbler.
The white-browed shrike-babbler is sexually dimorphic. There are many variations between the populations and some are more distinctive than others but they may not be easy to diagnose in the field. In general appearance it is very similar to the Himalayan shrike-babbler but all subspecies with the exception of validirostris have the tertials of males partly coloured rufous and partly fulvous.
The common name commemorates Edward Blyth (1810–1873), who published the description and notes based on Samuel Tickell's specimen. It was earlier called Tickell's shrike-Tit. The species Pteruthius aeralatus was described by Edward Blyth... Wikipedia →

Rare
Under 5% of wildlife watchers report a Blyth's Shrike-Babbler sighting in Kathmandu on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 265th most-seen of the 312 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 Blyth's Shrike-Babbler in Kathmandu on a given day, so our monthly data shows no clear season.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Blyth's Shrike-Babbler sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Kathmandu, in our data
Kathmandu is the only city on Wallace's Line with enough records to rate Blyth's Shrike-Babbler sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Blyth's Shrike-Babbler is recorded against all the birds logged in Kathmandu (13 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.
