Number observed: 2
Details: Two dark morph adults seen well for 10-15 minutes. Very similar in size to Ring-billed and California Gulls they were harassing. Distinctly falcon-like in flight, as opposed to somewhat tern-like flight in LTJA and powerful and bulky flight as in POJA. Very twisty and agile flight when harassing gulls.
Conspicuous single white patch on underside of primaries. Medium-length wedge-shaped tail.
They were observed resting on the water and harassing gulls together as a pair most of the time. Then one flew west towards the dam out of sight and the other one followed behind very shortly thereafter.
Here is a link to a poor video of one of the birds:
