| Occurrence Remarks |
The documentation form by David J. Conrads is the earliest and the one that forms the basis of this record. Other observers include Keith Franzen and Nixon Wilson. | Elimination of similar species: Due to its significantly smaller size than a Cooper's Hawk, we concluded that it was a HY male Sharp-shinned Hawk. We also listened to "A Field Guide to Bird Songs" and although the Sharp-shinned recording was that of 175 "kek-kek-kek" warning/alarm call, the Cooper's Hawk recording was that of a food begging call which was very similar but of a significantly lower pitch than that of the bird we observed. | The original documentation form event lasted from 14:30:00/14:31:00. |

| Event Remarks |
The viewing conditions were fair, the forest was quite shaded. We did not have any optical equipment but observed the bird from 20'-35' without aid. |
