Mayhew 1947 June 7 Great Horned Owl Strawberry Canyon, U.C. campus, Alameda Co., Calif. At 8:33 A.M. one was seen sitting on a dead branch of a [illegible] eucalyptus tree. He flew as soon as he saw us, to another eucalyptus tree about 200' away. He sat on the branch facing east. He sat in an upright position, occasionally turning his head. The branch on which he sat was about 40 feet above the ground. We approached to within 150 feet of the tree in which he was seen, but we didn't seem to disturb it. With binoculars, one could easily see the "horns" of feathers projecting above each side of the head. The breast was noticeably barred, the back mottled. On both the limbs on which it sat, it was rather exposed. However, the day was completely overcast, which may explain its seemingly unusual behavior. Other than turning its head, it made no movements at all that were visible from where we sat. At 8:55 A.M., as we approached the first owl, a second made its appearance, landing in a tree about 50 feet from the tree in which the other owl was sitting. A moment later the first owl flew out of my sight.
