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...

Possible
About 20% of wildlife watchers report a Gray Treepie sighting in Hangzhou on a given day, based on 252 verified sightings from GBIF citizen-science data. It is the 44th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August–October and December–February
In those months about 20% of wildlife watchers report a Gray Treepie in Hangzhou on a given day, against under 5% in March, the lowest month.
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 15
Of the 15 cities where we can rate Gray Treepie sightings, Hangzhou ranks 9th at about 20%. The best odds are in Kaohsiung (Taiwan, about 70%), Taipei (Taiwan, about 60%) and Tainan (Taiwan, about 60%).
Same family: Corvidae
The closest relatives of the Gray Treepie that you can see in Hangzhou (family Corvidae, Crows, Jays, and Magpies) are Oriental Magpie (about 50%), Red-billed Blue Magpie (about 40%) and Large-billed Crow (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray Treepie is recorded against all the birds logged in Hangzhou (252 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.
