Your tern in flight is particularly nice. I don't know if your terns act differently than mine...but if yours are like mine, that is a heck of a capture! I can't get those things anywhere near my frame until they land - they dart around at 35MPH and maneuver like butterflies, and are next to impossible to locate through the viewfinder before they're off in another direction. Amazing that two places so far away as yours and mine share much of the same birds!
