Heard this bird, then saw it sitting on a neighbors telephone pole. It was still dark out, so I had to use a few enhancing techniques to get this good an image. My first thought was Caracara, but the color seems wrong.
Quoting:...it sitting on a neighbors telephone pole.
Your neighbors sure must have an unusual high voltage telephone! Because, large heavy duty insulators like the ones in the picture are only used on high voltage electric lines. Telephones are normally low voltage.
