| Occurrence Remarks |
The documentation form by Ann Johnson and Jim Bangma is the earliest and the one that forms the basis of this record. | Elimination of similar species: The powerful direct flight, the longish tail, and the rounded broad wings identified this bird as an accipter. Bangma's first comment was that the width of the wings reminded him of Hook-billed Kites in So. Texas, a dramatic characteristic that allows experienced hawk watchers to identify Northern Goshawk from a distance - literally a stovepipe with broad wings. Buteos have a much shorter tail that gives them an entirely different look and feel. A gray adult male Northern Harrier would look white below and have longer wings proportionate to the body. Although we were unable to see the bird at an angle to see every characteristic of this species, other accipters would have been rufous or brown from below. Although this is certainly a late date for this species, Northern Goshawk has been seen in the winter in and near this location. In breeding areas it feeds on grouse. We speculated on the reintroduction of Ruffed Grouse in this area and what effect it might have on late migration and even potential breeding. | The original documentation form event lasted from 13:45:00/13:46:00. |

| Event Remarks |
Good light on a bird about 100 yards away. Most of the observation was naked eye but we both got binoculars on it to see the tail barring well. |
