The white-tailed nuthatch (Sitta himalayensis) is a species of bird in the family Sittidae. It ranges across the northern and northeastern parts of the Indian subcontinent, existing mainly in the low-to-middle Himalayas, as well as associated mountain ranges. It is found in Bhutan, India, Laos, Myanmar, Nepal, Tibet and Thailand.
It is 12 cm long, slightly smaller than the other related Himalayan nuthatches, and may be identified by the buff underside, smaller beak than in the Kashmir nuthatch (S. cashmirensis), and paler blue-grey mantle than others except for Kashmir nuthatch. The white patch on the centre of the upper tail coverts is difficult to see in the field. It has a small bill and pale orangey underparts with unmarked bright rufous undertail-coverts. The black eyestripe is broader than that of Kashmir nuthatch, and flared wider behind the eye.
It is resident in the sub-Himalayan range from Himachal Pradesh to Arunachal Pradesh and into the South Assam Hills (Lushai Hills). It breeds from March to May in broad-leaved and mixed forest. Its natural habitats are subtropical or tropical moist lowland broadleaf forests and subtropical... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-tailed Nuthatch sighting in Kathmandu on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 276th 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 White-tailed Nuthatch in Kathmandu on a given day, so our monthly data shows no clear season.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most White-tailed Nuthatch sightings with a recorded time, and about half of them come between 6 am and 6 pm: 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 White-tailed Nuthatch sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-tailed Nuthatch is recorded against all the birds logged in Kathmandu (12 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.
