Ten-minute point transect surveys were conducted in Denali National Park and Preserve, Alaska, as part of the Central Alaska Network’s Vital Signs monitoring program. Surveys were conducted between 1 and 21 June between 0300 and 0900 hours. All birds detected (seen or heard) at each sampling point were recorded during a 10-minute sampling period in one of four time intervals (0 to 3 min, >3 5 8 150-m). The survey crew sampled 194 points on 8 minigrids in 2006 and detected 1859 birds at 1782 detection events, including 167 to 300 birds per minigrid and 6.7 to 12.0 birds per point. Species richness ranged from 14 to 25 species per minigrid and 3.8 to 6.7 species per point. Seventy-two species were detected on minigrids (54 species during the 10-minute counts and 18 species on the minigrids but not during the 10-minute counts). Most detections (75%) were of members of three families, Emberizidae (Sparrows), Turdidae (Thrushes), and Parulidea (Warblers). Whitecrowned Sparrow (Zonotrichia leucophrys) was the most commonly detected species on the 10-minute counts (n = 413 detections, 22.2% of all detections).
