In more serious contexts in the game (outside events), Jingwei is the name given to the Celestial Phoenix, which includes its bird form as well (post #6640267).
In Honkai: Star Rail, the bird appears as Sushang's Ultimate and on her phone case. It has the same exact design as the first one described above.
Qingque's bird motif also bears a striking resemblance to the Jingwei. (post #6320353, post #6700199)
