Oriolus Chinensis, the newly observed bird, is about 25 cm long, with a broad black stripe around its head, just like a black band tied to its top, according to He Xin, an assistant researcher of the Shanghai Natural History Museum and a bird expert.
For Shanghai and other parts of eastern China, Oriolus Chinensis is a kind of migratory bird which only passes through the region in the migration seasons of spring and autumn, making it hard for tourists to see it every day, Xinhua news agency quoted the expert as saying.
"Besides, the bird is wary by nature and often hides in dense trees and bushes. It's a big surprise to see them at the Wishing Star Park," He added.
The park, adjacent to Disneyland and the hotels, was built for visitors to get close to nature.
Consisting of a lake as well as coastal wetlands, bushes and woods, it provides a favourable living environment for animals.
Opened in 2016, the resort is the first Disney resort destination on the Chinese mainland and the sixth in the world.
The resort said in June that more than 90 kinds of birds had settled in or flew across the wetland park after three years of operation, compared with around 60 kinds in 2017.
