The second bird was seen near Po Toi last year during a typhoon.
BUT in July 2021 we now appear to have two different Brown Noddys ("Noddies "?)at the same time in HK.
A bird - HK’s third - that has been around for 3-4 weeks in Mirs Bay - presently delighting photographers east of Tap Mun Island.

AND FOURTH, found by people last week tern-watching on the Cheung Chau to Central Ferry, this bird I photographed today, 21st July, also from the back of the public ferry.
Five photos of this very worn and abraded individual, and a couple of shots of one of the ferries (just like ours)
- someone going the other way seems to be looking out for the Noddy, too !
