About 6-7 inches long. Can't see any keeling on scales.
Observed RTHA nest from behind Shell gas station on US 183 and McKinney Falls Parkway. While watching nest, adult RTHA flew off nest and perched on nearest transmission line pole. I have observed adult RTHA in this area since September usually perched on utility infrastructure or flying over ag fields or areas adjacent to airport runways. Pictures are of low quality since taken with smart phone from a great distance.
Dark brown, with lighter crossbands.
Walked past my office windows. Incredibly skittish - didn't look domesticated, and lean and long-legged like a wild one, but I can't imagine where it could have come from.
