Out on the catio we've been keeping two plant coasters, a small terra-cotta one and a large plastic one, filled with clean water. Some birds drink and some bathe and some do both. Through the French doors, we've seen several different jays, a couple of titmice, our cardinal pair, and many wrens. Every morning, we find them empty: foxes, opossums, raccoons? During the day, squirrels drink and then stretch out belly-down to cool themselves on the shaded flagstones.
