Last night at midnight, while reading evening prayer, I heard a screech owl. It sat for several minutes in the catalpa tree outside my window and called to me until I was finally motivated to get out of bed, grab my slippers and start for the door of my bedroom. By then, though, it had flown off.
In the din that is midnight in my neighborhood, the thrum of traffic from the highway, the sounds of cars on the main road nearby, the crickets and tree frogs, I heard an owl for the first time in my life.
This site has samples of the song. My owl sang both last night.
