As you have perhaps seen in yesterdays post, we have two bird baths in the back yard. The smaller one is on a pedestal at the far end of the yard. There is a larger one nearer to ground level a little closer to the deck.
For their own curious reasons, the robins tend to prefer the smaller, shallower, and farther bath.
I sat poised with camera on the deck, and in a little while, a robin came and splashed around, quite vigorously at times.
My long zoom was fully extended in most cases, but the photos came out relatively clear. I was shooting at 1/400 second, but it still should have been faster to catch the flapping the wings more clearly.
