Are they Gull-billed Tern (鷗嘴噪鷗)?

Sorry, they are just too far away... :P

Black-winged Stilt (黑翅長腳鷸) are standing next to them.

Looks like Gull-billed terns to me as well.

They are passage migrant that usually come thru' Deep Bay in Apr/May time. Common terns that look similar (but smaller with longer tail feathers) usually come thru' around Aug/Sep.

Would experts pls help verify my guess.

I agree that the two birds standing sideways on and the single bird in the photo are Gull-billed Terns - neat back cap, fairly heavy and relatively short all-black bill, light-mid grey upperparts, pure white underparts and short (for a tern) tail.

I am not sure about the middle bird in the first photo (facing the camera). It is in partial winter plumage (which doesn't help) but is it also a little smaller and the bill a little finer?
