 84 THE CONDOR VOL. X Speotyto cunicularia hypogaa. Burrowing Owl. The small rocky ravines ex- tending halfway up the hillsides from the shore of the northeast coast, seemed to be' the favorite hiding places of the Burrowing Owls during the day. The speci- mens secured differ very slightly, or not at all, from those of the mainland coast district. Resident. Ceryle alcyon. Belted Kingfisher. Several seen. Sphyrapicus varius nuchalis. Red-naped Sapsucker. While hunting among the cherry and holl) bushes in a narrow valley in the high mesa above Mosquito Harbor, October 11, we secured two immature sapsuckers of this species. No others were seen on the Island. Colaptes caret collaris. Red-shafted Flicker. Frequently seen and heard in the canyons near Mosquito Harbor. An adult $ and  secured in October. Aeronautes melanoleucus. White-throated Swifts. Seen on several occasions. March 7, observed entering crevices in the cliffs near Howland's Bay. Selasphorus alleni. Allen Hummingbird. Fairly common in suitable locali- ties. April 1, I found a nest containing two fresh eggs; April 7, another contain- ing one fresh egg, and two unfinished nests. As I left the Island April 7, I only preserved the complete set and nest of April 1. These nests were composed of wool and spiderwebs, partially covered with lichens and placed on low-hanging twigs of holly and cherry bushes in the canyons. Tyrannus verticalis. Arkansas Kingbird. One seen near the spring, Mos- quito Harbor, April 3, and on the 5th I secured an adult 9 in the same locality. Sayornis saya. Say Phoebe. Fairly common over whole Island, excepting the Smugglers' Cove region. Sayornis nigricans. Black Phoebe. Seen only along northeast coast. March 20, an unfinished nest was found fastened to the side of a cave just above high tide mark. One specimen preserved. Empidonax diflicilis. Western Flycatcher. The first pair was observed April 1, in a deep gorge near Mosquito Harbor. April 3 several were seen and secured. Only three or four noted during October. Otocoris alpestris insularis. Island Horned Lark. Very common over the whole Island. Large series secured. Corvus corax sinuatus. Mexican Raven. Abundant resident. Nesting in the cliffs, often on ledges directly over the water. A large series preserved. Among these were several specimens that would easily have passed for the much sought for "Clarion Island Raven." It is my opinion they are Corvus co}ax sinuatus birds-of-the-year. The size and general appearance coincide with the description of the 'Clarion Island Raven. Altho common at present the ravens are being rap- idly exterminated thru the use of poisoned carcasses, by the sheep men who (rightfully) accuse them of killing many young lambs. Sturnella neglecta. Western Meadow Lark. Common on the mesas of the coast, and inland. Icterus bullocki. Bullock Oriole. One adult male secured March 31. Carpodacus clementis. San Clemente Linnet. Abundant resident everywhere. Several nests containing incubated sets were found in the sheds at Howland's, March 1. Others were found near Mosquito Harbor, in the cacti and sage. March 9 to April 7 a large series of skins were preserved. The feathers about the base of the bills of several specimens were stained with the juice of the "cactus apple." This fruit forms the chief food of many island birds during certain seasons. Zonotrichia querula. Harris Sparrow. While watching the House Finches, Song and Gambel Sparrows drink and bathe in the sheep troughs at the windmill,
