Need help with Texas Terns (1 Viewer)

[ednamex]

I'd got terns down last year - well, half-down anyway - but now I'm back to square one.
Can anyone help with the ones in the photos? I can't sort them out at all. They're all from the past two days along Bolivar Peninsula.

The large ones with the orange bills are royals. My guess (I'm doing this without my book at the moment) for the smaller black billed terns are foresters. Off hand I don't see Sandwhich but I could be overlooking them and my experience with common is minimal.

Someone will remark on the smaller ones for sure

I could only see Forster's amoung the smaller terns. I wondered if a couple of the larger terns could be Elegant, though most look like Royals

Edit, and at least one Sandwich in pic 4, to be honest it's late and haven't looked all that closely

There is a Sandwich in picture two on the right.
