Glaucous Gull, Deep Bay
I had a message today from Brendan that a Gloucous Gull was seen in Deep Bay from Tsim Bei Tsui. As well as TBT, I expect it may also be visible from the Mai Po Boardwalk (although maybe distant, according to the tide).
Good luck to anyone who goes out to look for the bird, and hopefully someone will update here with more details later.
