The grey treepie (Dendrocitta formosae), also known as the Himalayan treepie, is an Asian treepie, a medium-sized and long-tailed member of the crow family. The species was first described by Robert Swinhoe in 1863. They are widely distributed along the foothills of the Himalayas in the Indian subcontinent and extending into Indochina, Nepal, southern mainland China and Taiwan. The populations vary in plumage and several are named as subspecies.
Grey treepies are omnivorous birds mostly thriving among dense foliage and in forests. They sometimes take part in mixed species flocks with laughingthrushes, especially the white-throated laughingthrush. They systematically work together through the hill forests, rhododendrons, oaks and other broad-leaved trees, especially in the mornings.
The grey treepie is 36–40 cm (14–16 in) long and weighs 89–121 g (3.1–4.3 oz). It is the same size as other Dendrocitta species and is separated from them by the overall grey colour of the body. The races in the western part of the distribution have a greyish rump and some grey in tail while the eastern forms have a white rump and a black tail. The face and throat are dark and black with...

Rare
Under 5% of wildlife watchers report a Gray Treepie sighting in Chitwan National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 305th most-seen of the 367 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Gray Treepie in Chitwan National Park on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Gray Treepie sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
9th of 9
Of the 9 parks where we can rate Gray Treepie sightings, Chitwan National Park ranks 9th at under 5%. The best odds are in Royal Manas National Park (Bhutan, about 40%), Namdapha National Park (India, about 30%) and Taroko National Park (Taiwan, about 20%).
GBIF citizen-science records
It is estimated from how often the Gray Treepie is recorded against all the birds logged in Chitwan National Park (10 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.
