Remsen, J.V. 1974 Saw-whet Owl Aegolius acadicus Feb.4 Redwood Regional Park, Alameda Co., Calif.: I found in picnic area at the end of the paved road. I had given imitations for less than a minute when a bird swooped right over my head twice. After disappearing for a minute, it began to answer my calls and then the battle was on. It flew onto an exposed branch of a fruit tree about 40 feet away and we watched it for about 30 seconds in the flashlights with binoculars before it disappeared. Then we moved away to a nearby picnic table, sat down, and I began to whistle. Within 30 seconds, the bird had dive-bombed us twice, coming as close as 4 feet above my head. It then landed in a fruit tree within 7 feet from our heads, and we had fantastic views in the flashlights for 30 seconds or more be- fore it flew. We then left the area but the owl continued to sing without pausing for at least 5 more minutes. Later on, when we were 100 yds away, I gave a couple of Spotted Owl calls but the Saw-whet continued to call. The moonlight really helped in locating the bird - you could see it with the naked eye perched and in flight. McDonald Trail, Chabot Reg.
