I realized the American Avocet Pair was moving further and further from me, so focused instead on trying to capture a Tree Swallow. It was a grey, sunless day, so the iridescence of their wings was also dull.

A small flock of them were feeding over a pond, zipping in unpredictable patterns over the water.

I’m sure they were capturing insects, but that action was undetectable.

They often swooped near each other, but never crash.

Last second change of flight plan was pretty common, showing off flight skills.
