There were a lot of birds in the back yard this morning, coming down to the bird bath on the edge of our patio. They often fly to the lower branches of the nearest maple tree first, and then fly down to the edge of the bath. The goldfinches often land on a metal pole, even closer. Then there are the catbirds (grey catbirds, to be precise, Dumetella carolinensis). They land in and around the potted plants and often perch on this leaning garden ornament (which doesn’t light up any more, but we haven’t gotten around to removing it). I especially like watching the way birds stand on sloping and moving objects, with a sophisticated auto-balancing system that works wonderfully to keep them upright with little or no effort.
