The documentation form by Barbara L. Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: Tail too long + flight too quick + direct for a Red-tail. Wings rounded - not a falcon. Young accipiter (+ many buteos) would be streaked below. Adult accipiters of other kinds would be barred below, but reddish or brown, not gravy. Marsh Hawk would fly with a more leisurely pace + have longer wings. As I saw it, identifications went clicking through my brains one after another. Red tail? No.. Marsh Hawk! - No ... Coopers Hawk! Yes - no - its gray! I certainly did not expect a Goshawk.
