February 25, 1947 - Oak-Fir Hills 3 miles west of 12-mile Swamp. 11:5-3 p.m. -North 12-15, warm. Habitat Oak-Fir. Winter Wrens - a pair of them within 8-10 feet of a pair of Seattle Wrens in some brush beside the road. Varied Thrush - a few seen in this mixed forest. In the underbrush till flushed. Sparrow Hawks - hovering over nearby fields. Same, Habitat - Fir W. Redtailed Hawks - flushed what looked like a female from an old oak, rather deep in the fir woods. It flew out over an open field and continued on. As we watched it get farther away, we heard a crescendo roar of air directly over our heads, but couldn't figure it out until about 300 yards off, we saw this "bolt from the blue" diving past the bird we flushed, with folded wings. Hardly had we finished seeing that and we heard another loud roar of air, and a second bird came diving at the area where the flushed bird was. The angle of descent of both these birds was about 60° from the horizontal. All three then chased each other off to another area, flying rather low. Later, when we reached the ridge-top, I spotted a red-tail sailing very high, in a straight line to the west. After about ¼ mile it dropped its angle of flight a little, and gained speed, swooping upward, then, toward another bird that we hadn't seen circling before. After gaining sufficient altitude near this 2nd bird, it folded its wings and plummeted nearly straight down, pulled out, and climbed straight, almost, in a short loop, and from what we could see, it winged clear on over in the loop, folded its wings, and went into another dive, and loop - this was down a total of 8 times, before the distance away was too great for us to see. Mountain Quail - we flushed a covey of 8 or 10 of them at the edge of a wheat field, and fir woods. We could not approach very close to them. One gave a short, soft, call not as they flushed. They were quite noisily in the brush. Great Horned Owl - flushed one twice ahead of us in an oak-fir mixed woods, near the top of the ridge. ??? - Long-eared Owl - ??? - flushed one ? from a fir woods on the south slope of the ridge. This identification is made only by elimination, for we didn't see enough to be sure. We are judging it only by size, as the only possible owl that it could have been. Flickers - seen and calling in the oak and fir now and then. Coast Jay - saw a couple. Gave regular scolding notes, as well as the old "Red-tail Hawk" routine. Oregon Chickadees - working through the fir in company with Chestnut-backed Chickadees, and Red-breasted Nuthatches, and California Creepers. Winter Wrens - seen and heard. Seattle Wrens seen and heard, scolding. Varied Thrush - saw a couple in the fir, and deeper oak woods. Ruby-crowned Kinglets - still seen as individuals. Golden-crowned Kinglets - a small flock working the firs. Hutton's Vireo - seemed to be quite a few in the area today. I learned three different call notes of their's today. One is a buzzing scold note, I believe. The call notes are crystal clear, and seem to carry quite a ways. 2-27-47 "Prison Oak" Lake, Linn Co. - 1:3p.m. -O/NT Killdeer Mourning Doves - on a wire line. Flickers - a few calling Violet-green Swallow - just one flying over the lake. Very few insects present. Long-tailed Jay - scolding Oregon chickadees. Seattle Wren - scolding Robin Ruby-crown Kinglet Towhee Warblers singing Sparrows 15 White-crowned Sparrows Song Sparrows.
