So it was really ridiculous to think that the night heron wouldn't come back. After all, birds fly for thousands of miles. They have that whole bird's eye view of the world. While it might be a challenge for a human to find his or her way back to place after a disorienting 10 mile car ride, it is not difficult for a bird.
This is a picture of a "cotillion" of terns. I took it last week at sand's beach. I like how sharp they look in flight -- like someone threw hundreds of pairs of scissors up into the air.
