Yesterday I shed three tiers

A correction: Yesterday when observing the huge numbers of grackles and starlings roosting in the trees around the Pulitzer Fountain, I wrote that the fountain had three water-filled tiers where the grackles drank and bathed before roosting. Today I watched the roosting drama from a bench a few feet away from the fountain, rather than from across the street . I could now see that there were six circles of granite, not three. The birds only used the top three, however.
