Birding the Point – Terns and Gulls

This is the second post in a series of posts from my birding adventures at Black Point Marina in southern Miami-Dade County, Florida.  On a recent visit I was able to get a great shot of a lineup of Royal Terns.  I also captured images of a couple of gulls in flight.

Royal Terns lined up at the point.

I’m going to need some help with this one.  What do you think this is?
