 146 THE CONDOR VoL. XI cactus, and a careful scrutiny reveals an Owl's head projecting above the rim of the nest. February 28, I found two eggs in an old Redtail's nest, 60 feet up in a cotton- wood tree. Both old birds were at home but made no demonstration when I climbed to the home. A Redtail that percht in the top of a neighboring tree did not escape so easily tho, as the male owl savagely attackt him, and drove him off. March 14 another nest was found containing two eggs. This nest was merely a decayed hollow in the forks of a big cottonwood tree, 15 feet from the ground. The nest was discovered by throwing a club into the tree, when the bird flew out. GIANT CACTUS (CEREUS GIGANTEUS); A 'ESTERN HORNED OWL IS TO BE SEEN ABOVE THE EDGE OF THE NEST IN THE FORKS Nothing had been visible, but the tree lookt owlish, and a bombardment brought results. For at least four years a pair of these owls have nested in the pre-historic Casa Grande ruins; see photo by Frank Pinkley, the custodian. Mr. Pinkley told me the birds raised a brood each year in the old building, and had never been molested except once, when one of them developt a decided taste for prize Wyandot chickens. This was his undoing, but his widow secured another mate very soon and went on keeping house as tho nothing had happened.
