Hello John. I have been photographing terns at Sai Kung recently. There's been plenty, but not so many White-winged, as far as I can tell. I believe your third photo is of a non-breeding bird, but how does one distinguish between a non-breeding White-winged and a non-breeding Whiskered? Even the photos in the HKBWS Photographic Guide of these two look very similar to my inexperienced eye.
