There's a small tern on the west shore of Prince Lake 2 (3:30pm, Sun) with black cap that extends down back of neck that looks like a match for Common Tern or Least Tern, but it looks to be about a 1/3 the size of the nearby Ring bill gulls, so possibly Least Tern?

Common Tern at Prince Lake 2

I was able to get another look at the Prince Lake 2 tern (5PM), and was able to see a distinct dark carpal-bar, so I believe that it is a Common Tern.
