| Occurrence Remarks |
The documentation form by Mark Osrag is the only one submitted and forms the basis of this record. Other observers include Sue Mattix. | Elimination of similar species: Dark immature gulls were eliminated by flight pattern, body-to-wing shape profile (as above), and the well seen identical translucent patches on the wings. Other jaeger species were eliminated by the bird's size. It thermalled above a wetland area beyond HNA's 'Westridge' with a group of Ring-billed Gulls. Size comparison was perfect-revealing a noticeably larger, heavier-bodied bird. | The original documentation form event lasted from 14:45:00/14:55:00. |

| Event Remarks |
Viewing Conditions: Distance was maybe a quarter-mile to half a mile, maybe a bit less at one point. Light was good with good color/contrast showing through both "scopes". Sue's is a Bausch and Lomb, my tripod mounted binoculars are the 30x90s detailed at the end of the Ferruginous Hawk documentation. We each viewed the bird through both "scopes". |
