Birds

They usually play around the 3-tiered cascade, but the bottom part where the pump is leaks, so the ones that hold water are the upper cascades where birds bathe and play for days. I usually let the fountain run for a couple of hours before turning it off but for days, the front yard's been uncharacteristically quiet. The birds are gone! It's been completely dewatered that's why, even the green algae has dried and became just a brown stain on concrete. I know just what to do. Now, where's that hose....
