In 2011, we completed the first field season of long-term bird monitoring associated with the Inventory and Monitoring Program of the Sierra Nevada Network (SIEN). Field work included data collection on the annual panel as well as the first of four alternating panels. Crews conducted 744 point counts at point count survey stations located along 51 transects in Sequoia and Kings Canyon National Parks (SEKI) and Yosemite National Park (YOSE). The average number of points visited per transect was 14.6 (range = 10-22 points per transect). We also completed surveys at the 42 point count stations at Devils Postpile National Monument (DEPO), which are arranged in a grid pattern. We detected 121 bird species in the two large parks, 96 of which were detected during one or more point counts, and the remainder of which were detected by our crew members only at times other than during point counts. For the 72 species that were detected during three or more point counts on annual-panel transects in 2011, we present the total number of detections on annual-panel transects in each park during the 2011 field season. We detected 42 bird species during point counts at DEPO. We present the number of detections, and the number of point counts with detections, for each species detected during point counts at DEPO. These data, along with data collected in future years, will be adjusted for differences in survey effort or detection probability in conjunction with our 4-year trend analyses.
