Event Remarks |
Viewing Conditions: The light was fading but adequate. The owl was first observed from 20 feet for approximately three minutes. It then flew to another fence post and we observed it from about 40 feet for about 10 minutes. It then flew again unnoticed. We found that it had flown across the road to another fence post the same distance away. We observed it for approximately seven minutes. We had it possitively [sic] identified by this time and in attempting to agitate it to observe its behavior, it flew and its flight was noted. We lost sight of it in the corn field. As we left the area heading south we observed what we feel was the same owl sitting on a post between a quarter to a half mile away from the first sighting. It had been approximately five minutes since we lost tract [sic] of it. We used Bushnell Spotting Scope and binoculars 7-15 X 35 zoom. Distances were approximated by visual observation and land marks, i.e. road ditch widths. |
