These data document observations of birds, mostly in canyons and a small proportion in intervening valleys, throughout four mountain ranges in the central Great Basin (Lander, Nye, and Eureka counties, Nevada): the Shoshone Mountains, Toiyabe Range, Toquima Range, and Monitor Range. Data were collected from 2002 through 2012, inclusive. These data complement those in Fleishman (2015b), which included detections of breeding birds during fixed-radius point counts within 100 meters of the observer. The data in this data publication allow more-complete documentation of the composition and distribution of the local and regional avifauna than would be possible with the fixed-radius point-count data alone. Some birds documented in these data were detected during fixed-radius point counts but were outside the radius of the sample point (e.g., >100 meters from the observer) or flying over the point rather than apparently using resources within the point. Others were detected opportunistically while traveling to sampling locations. The records also include juveniles, which are not included in published analyses. Data include species detected, date of detection, and, in most cases, method of detection and either coordinates or an approximate location.
