June 23, 1948, Cottage Grove Reservoir, LaneCo. 0800-1600, clear, warm N3-15 Gordon Gullion, Ben Pruitt, and I Pied-billed Grebe - I heard my old "coot calls" today, but on tracing them down I saw nothing but these grebes, so I will have to change my previous records entered under the "coot", calls, nest and all !!!! Saw them in 2 different areas. Watched one raise its tail and head and slip under water in a "V" without making so much as a ripple. Blue Heron - just one seen Green Heron - I flew up and down the river area above the reservoir. Mallards - a flight of 10, also a pair with eggs or young, but we couldn't find them. Wood Ducks - a flight of 7, and then 1 full male in pond-lily slough in woods. Turkey Vulture - just a couple or 3 seen over the water, others over hills Cooper Hawk - saw a couple of them, perhaps the same one twice. Reatail Hawk - one seen Osprey - heard a "hawk" screaming weakly - finally located an adult osprey at a height of about 2000-2500 feet. It was sailing SW, soon after this another adult came over lower, in the same direct, and then an immature bird, in brown plumage, and later, on the lake, we saw another adult. Sparrow Hawk Mountain Quail - a few along brush in fir area on north slope. Mourning Doves - a few Barn-tai-ied Pigeon - a flight of 5 went over Vaux Swift - two over river area. Rufous Hummingbirds - many seen in woods edge and elsewhere. Flicker - nest at 25' in broken, rotten, but living fir, in partly cleared area. Opening to NE side. Birds went in an out, feeding young while I watched. NW Red-breasted Sapsucker - one in fir forest area. Little Flycatcher - must have seen and heard over 50 or 75 of them. Found nest just completed, but containing no eggs. On north side of clump of Doughias and white fir, in tall bracken fern growth at 4 feet above the ground, on a northeast slope, near where we located the Wren-tit! The nest had outside measurements of 3-4" deep and 31/2" diameter. Inside diameter 1 3/4" and inside depth was 11/2". Nest of grass with pieces of green moss. Fine grass and hair lined the nest. Nest in crotch of the fern. Horned Lark singing in field area. Violet-green Swallow Tree Swallows Rough-winged Swallow - nest burrow in 3' bank along the Willamette river above the reservoir -NNW bank. Burrow 2" above water, flat on the bottom, and oval arched. About 8" deep, into larger chamber, but we couldn't see for grassy sides of nest blocked view. Adult in burrow at 1215. Barn Swallows Cliff Swallows Stellar Jays - in the timber Raven - several seen Crow - a few Chestnut-backed Chickadee in fir forest Bush-tita - a few in brush at edge of fir forest. Red-breasted nuthatch - calling off and on from fir forest areas. California Creeper - singing and calling in fir forest Coast Wren-Tit !! Gordon Gullion first heard and saw it in a dense thicket on a northeast slope in the fir forest. We all got to view it for a considerable time. It was easily "decoyed", and I imitated its call easily, bringint it within arms reach of me several times. It was quite a rich brown color, so I assume it was this subspecies. It sang with us within 5 feet of it, and talking. I thought I noted a grayish, short arch of color over the eye. It flitted or ran along the brush limbs. The astonishing thing to me was not just to find the bird, but to note the habitat of the small area in which we found it, and in which it stayed, and circling around us while we watched it. The area was a thick tangle of vegetation, heavily shaded, moist, and cool. Douglas Fir, Hemlock,Chinquapin, and dogwood. Various shrubs including thick growth of salal to heights of 4 feet. Heavy, damp moss layers covered the ground in this area. We saw only the one bird.
