To be even more specific, this is the newly described bohaii sub species of Black-tailed Godwit. https://bou.org.uk/blog-zhu-black-tailed-godwit-bohai-bay-subspecies-china/

The bohaii sub species is our common winter visitor, while our spring passage migrant are sub species melanurodies, which usually come pass Deep Bay in nice colourful breeding plumage.

Cheers,
