The blue nuthatch (Sitta azurea) is a bird species in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring 13.5 cm (5.3 in) in length. The species, which shows slight sexual dimorphism, has dramatic plumage pattern unlike any other member of its genus. Its head is black or blackish-blue dark blue upperparts close to purple with azure feathers. The wings are edged with black. The throat and chest are white or a washed buff, contrasting with the upperparts and the belly of a very dark blue; the covert feathers are generally clear, blue-grey or purplish.
The blue nuthatch's ecology is poorly known, but it feeds on small invertebrates found on trees; reproduction takes place from April to June or July. It also forages in mixed-species flocks in larger groups. They can be found in the Malay Peninsula and on the islands of Sumatra and Java in Indonesia, where it inhabits subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest above 900 m (3,000 ft) in altitude.
The species' closest relatives are the velvet-fronted nuthatch (S. frontalis), the yellow-billed nuthatch (S. solangiae) and the sulphur-billed nuthatch (S. oenochlamys). The population of the species has not been determined but the species appears to be at low risk of extinction because of the extent of its distribution. It has been classified as of least concern by the International Union for Conservation of Nature. Wikipedia →

Possible
About 20% of wildlife watchers report a Blue Nuthatch sighting in Kerinci Seblat National Park on a given day, based on 146 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 43rd most-seen of the 203 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.
May, July and September
In those months about 30% of wildlife watchers report a Blue Nuthatch in Kerinci Seblat National Park on a given day, against about 10% in March–April, June and November, the lowest months. January has too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Blue 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 Kerinci Seblat National Park, in our data
Kerinci Seblat National Park is the only park on Wallace's Line with enough records to rate Blue Nuthatch sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Passeriformes
The closest relatives of the Blue Nuthatch that you can see in Kerinci Seblat National Park (order Passeriformes, Perching Birds) are Grey-headed Canary-Flycatcher (about 70%), Gray-throated Babbler (about 60%) and Golden Babbler (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue Nuthatch is recorded against all the birds logged in Kerinci Seblat National Park (146 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.
