Jerry, here\'s one addendum to your tern study: the Caspians are quite large, in fact probably about twice the size of the Common ones.
They have very stout bright red bills and black legs. They also fish/dive from much higher altitude. They are not much of a BIF challenge because they resemble larger seagulls in fligh, and they stay clear off the shore.... they clearly prefer open exapanse of water.
I seldom photograph them.
