Very dry here, so someone placed a small bowl to catch overflow from the drinking fountain for benefit of thirsty chickadees. One Echo Azure was taking full advantage.

It was finally a good day for hairstreaks, not in quantity but a nice variety. Three Whites seen in a wooded area may have been Mustard Whites, could not confirm.
