Gull-Billed or Whiskered Terns?
Taken at Sai Kung 30th May.
Can someone please help me to decide if these are both Whiskered or Gull-billed terns.
Thanks in advance.

Both Whiskered Terns. The first one is only partly in breeding plumage. Notice the dark underparts and dark red bill characteristic of breeding-plumage Whiskered.
