Mayhew 1947 June 7 Western Mourning Dove Woolsey Canyon, Alameda Co., Calif. At 9:50 A.M. we came upon 2 individuals sitting all humped up on branches of a live oak tree that had fallen over. They were only about 4 feet above the ground. We sat within 20 feet of them without disturbing them in the least. They were sitting about 18" apart on separate small branches, one facing north & the other one facing east. Dr. Miller approached & within 8 feet of them, & determined that they were young doves. When he approached a little closer, the nearest one flew about 6 feet to another branch. Then the remaining bird flew into a near-by tree. The nest from which they came was found in a little depression on a horizontal branch of the live oak, about 20 feet above the ground. The nest consisted of many sticks & some grass stems. The droppings of young doves were found in abundance. The branch itself formed the bottom of the nest, with a few branches across the bottom. As Dr. Miller saw the nest being built on May 3 (7 sticks at that time) it was rather surprising to find the young out of the nest already.
