While walking at first light a couple of weeks ago I heard distinctively different (and very loud) crowing coming from the alley where Walnut curves south around Kansas Street … so I decided to investigate. There I found three crowers — a red, a black and a white rooster who I’ve named Luciano Pavarotti, Plácido Domingo and José Carreras. Cocks whose volume was all the louder because they’d climbed into the bare branches of a redbud tree to broadcast.
