At about 7:40 this morning (Thursday) I saw that all the birds were agitated out my office window. Well, a Peregrine Falcon was perched on top of the closest office building I see from my office! A passing Ring-billed Gull took a swoop toward the falcon. The falcon soon took off and flew just over rooftop level and then out of sight, still stirring up pigeons, crows, and starlings. In the low morning sun, without binoculars, I wasn't sure about the color of the hawk's back. A great way to start the morning. Rob
