|Western Birds solicits papers that contribute significantly to the scientific literature and that are useful and accessible to professional and amateur field ornithologists. The journal welcomes contributions from professional and amateur scientists alike. Appropriate topics include distribution, migration, status, identification, geographic variation, conservation, behavior, ecology, population dynamics, habitat requirements, the effects of pollution, and techniques for censusing, sound recording, and photographing birds in the field. Papers of general interest will be considered regardless of their geographic origin, but particularly desired are reports of studies done in or bearing on the Rocky Mountain and Pacific states and provinces, including Alaska and Hawai'i, western Texas, northwestern Mexico, and the northeastern Pacific Ocean.|

Front cover photo by © Sophie Webb of Felton, California: Northern Gannet (Morus bassanus), Southeast Farallon Island, San Francisco County, California, 25 April 2012. It remained at least through February 2013 and is the first of this Atlantic species recorded in the North Pacific Ocean. Possibly the recent decrease of arctic ice allowed it to traverse the Arctic Ocean and enter the Pacific through the Bering Strait.
Back cover: “Featured Photo” by © Beth Hamel of Morgan Hill, California: Hairy Woodpecker (Picoides villosus), Golden Gate Park, San Francisco County, California, 26 October 2012. The yellow rectrices represent an unusual case of carotenism, affecting both the type and distribution of carotenoid pigment. Yet such carotenistic Hairy Woodpeckers have been noted repeatedly in coastal northern California.

Back cover “Featured Photos” by © Michael A. Schroeder of Bridgeport, Washington: (top) Dusky Grouse (Dendragapus obscurus), male near Turner Valley, Alberta, 14 May 2005. This male has red apteria on the neck, apparently typical of all Dusky Grouse; (bottom) Sooty Grouse (Dendragapus fuliginosus), male south of Terrace, British Columbia, 15 May 2008. Red apteria appear to be the rule in Sooty Grouse from Terrace north through southeastern Alaska, rather than yellow as they are farther south.
