July 23, 1946, "Poison Oak" Lake, Linn Co. 1 - 3 p.m. NW wind, clear and hot. Mallard - flushed a female from almost underfoot in the smartweed this p.m. Anthony Green Heron - adult on the nest at 1 p.m. Doc Gordon worked around the lake with camera and tripod, and the bird, although nervous, stayed on the nest with him only 25 feet away. As he approached, the young, which had been standing on the edge of the nest, on each side of the adult, took shelter under the adult bird. Doc took pics, moved closer, and took even a few more. Then I worked up toward the nest to get action out of the bird. It rose from the nest, and stalked along the limb into the center of the tree, and then flew into an adjoining fir tree. The young are quite active in the nest, and perch upon the edges frequently, sometimes almost losing their balance, but somehow regaining it awkwardly. The pin feathers are really coming out fast, and the down is almost a blue-gray now. The skin is tinted yellowish in places, and greenish in others. The legs are a yellow brown green. The iris is a golden-brown. We took movies and stills at the nest, and then I reached for the birds to band them. The older of the two took off the opposite side of the nest, and walked out on a limb about a foot or so from the nest, and wouldn't come back to where I could reach it. The other one hung to the nest sticks tightly, and wouldn't release its hold until I let it cling to my fingers. There were still 3 eggs in the nest. The eggs must be no good, for they certainly would have hatched by now. July 25, 1946 - "Poison Oak" Lake, Linn Co. 8-11 a.m. NW wind, clear and warm. Climbed to the Anthony Green Heron nest again, but both young ran out on limbs away from the nest, where I couldn't reach them. The parent bird circled around close by over the lake, and landed in a nearby oak, uttering its "unk" "unk" notes I gave up and returned to the nest later, and the young were back in the nest, and and adult left the nest again. As I reached for them, they scrambled out onto their limbs, again. The oldest one (the one I didn't get to band the 23rd) went out the very same limb all three times. However, the younger of the two birds, went out different limbs both of the times it retreated. I rocked the limb up and down and each time the limb went down, the young instinctively spread its wing, undeveloped as they are. Finally I took a long stick and got it to perch on it, and then I lifted it in to me. I took it to the ground, banded it, and photographed it. Thewing pinions are coming rapidly, as both the primaries and secondaries have grown considerably. The primaries on the oldest bird are about 2 1/2 inches long now. And when I held it, it tried to pech at me with its long bill. The down is turning darker and darker every day. July 27, 1946 - I watched a Green Heron circling over the campus, and it soon came to rest on the edge of the Commerce building roof. July 29, 1946 - Drift Creek Canyon - Wood Duck, Kingfisher Little Abiqua - two Pileated Woodpeckers, nest in top of 60' snag, opening to the SW. Aug. 1, 1946 - Stewart Lake - Saw 2 Robins chasing a Red-Tail Hawk. It retreated. August 2, 1946, "Poison Oak" Lake, Linn Co, 3 miles east of Corvallis. Saw one adult Green Heron carrying a 5" fish in its bill, as it alit on an oak snag. I visited the nest, and as always happens to any nest I watch, and then go away for a while, it was torn up, and the dud eggs were floating in the water under the nest. Not much of the nesting material was left. No sign of the young. I can hope that they have left the nest before it was torn up by whoever, or whatever did it. All the vegetation below the nest was thoroughly "whitewashed" by the birds, compared to the amount present when last I visited the nest. The adults seem to have special trees that they habit, and through which they move when they work their way around the lake.
