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...

Likely
About 60% of wildlife watchers report a Gray Treepie sighting in Taipei on a given day, based on 16,856 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 266 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 80% of wildlife watchers report a Gray Treepie in Taipei on a given day, against about 30% in January, the lowest month. That is one of Taipei's wettest months, with about 240 mm of rain against 90 mm in February.
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.
2nd of 15
Of the 15 cities where we can rate Gray Treepie sightings, Taipei ranks 2nd at about 60%. The best odds are in Kaohsiung (Taiwan, about 70%).
Same family: Corvidae
The closest relatives of the Gray Treepie that you can see in Taipei (family Corvidae, Crows, Jays, and Magpies) are Oriental Magpie (about 70%) and Formosan Magpie (about 20%), 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 Taipei (16,856 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.
