At dawn in the Bear Creek Greenbelt:

Great Horned Owl

A little later in the morning, at a nest a mile or so away, high up in a cottonwood, the sun bright behind:

A Spanish-speaking gentleman was also taking a picture with his phone. “Halcón?” he asked me.   I shook my head.   I didn’t know how to say owl in Spanish, and he didn’t understand the English word.  So I made a hooting noise.  “Ah! ” he said.  “Búho.”
