The black-collared starling (Gracupica nigricollis) is a species of starling with black and white plumage and a black collar. It is found in southern China and most of mainland Southeast Asia, and has been introduced to Taiwan, Malaysia and Singapore. Its habitats include grassland, dry forest and human settlements. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.
This species was described as Gracula nigricollis by Gustaf von Paykull in 1807. Formerly placed in the genus Sturnus, it and the Siamese pied myna (Gracupica floweri) were separated to the genus Gracupica when Sturnus was split, following phylogenetic studies in 2008. In the past it had also been placed in Sturnopastor, Acridotheres and Graculipica.
The black-collared starling is 26–30 cm (10–12 in) long. The head is white, with a yellow patch of bare skin around the eye, and a black collar around the neck. The mantle, back and wings are dark brown, appearing almost black. The underparts are white, often with a grey-brown tinge. The tail and most of the covert and flight feathers are tipped white, with the primary coverts completely white... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-collared Starling sighting in Chengdu on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 129th most-seen of the 156 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.
June and July
In those months about 10% of wildlife watchers report a Black-collared Starling in Chengdu on a given day, against under 5% in August to May, the lowest months. Those are among Chengdu's wettest months, with about 200 mm of rain a month against 10 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black-collared Starling 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.
25th of 26
Of the 26 cities where we can rate Black-collared Starling sightings, Chengdu ranks 25th at under 5%. The best odds are in Tuen Mun (China, about 70%), Taipei (Taiwan, about 70%) and Hong Kong (China, about 70%).
Same family: Sturnidae
The closest relatives of the Black-collared Starling that you can see in Chengdu (family Sturnidae, Starlings) are Red-billed Starling (about 30%), Crested Myna (about 30%) and White-cheeked Starling (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-collared Starling is recorded against all the birds logged in Chengdu (9 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.
