Gull-billed Tern. Facial pattern, bill and width of wing fit well.

Thank you very much HFCheung. So it is a juvenile bird as the top of the head not completely black!
This bird was very active and flew around.

It's a winter-plumaged adult, not a juvenile. Possibly a first-summer bird that will not breed this year.
