closed mark-recapture methods to estimate mean detection probability and evaluate the assumption that the expected value of mean detection probability was similar among study areas. Our objectives were to: (1) evaluate use of an auditory mark-recapture technique to estimate mean detection probability of crowing male pheasants; (2) assess the validity of using replicated roadside surveys by comparing roadside indices to crowing indices (adjusted for detection probability) across the 18 study areas; and (3) evaluate factors that may influence the accuracy of roadside and crowing indices. STUDY AREA This study was conducted on 18 study areas in southern Minnesota. To facilitate pheasant surveys, 9 study areas were selected in each of 2 regions located near Windom and Faribault, Minnesota (Figure 1). Study areas averaged 23 km 2 (9 mi²) in size and varied in the amount and distribution of grassland habitat, winter habitat, roads, and relative pheasant density (Haroldson et al. 2007). METHODS We conducted 10 crowing and 10 roadside surveys on each study area between 20 April and 31 May 2007. Crowing surveys and roadside surveys were scheduled independently (not necessarily on the same days). Trained observers conducted surveys on mornings meeting standardized weather conditions; however, surveys were completed even if weather conditions worsened during the survey. Observers rotated systematically among study areas to reduce the effect of observer bias. Crowing Surveys 44 We located and conducted surveys at 9 stops on each study area. Stops were evenly distributed across each study area, based on an estimated 0.8 km (0.5 mile) auditory radius, to achieve maximum possible coverage of the study area and minimize overlap among stops (Figure 2). Where possible, we located stops on roads to facilitate convenient access. Where roads were not available, we located stops up to 0.4 km (0.25 mile) from roads. Due to road coverage and landscape obstacles (e.g., lakes), 2 study areas had only 8 stops. Crowing surveys began 45 minutes before sunrise and were completed by sunrise on mornings with
following the first listening period. The second and third listening periods identified which birds heard during the first period were heard again, and also birds that had not previously been heard. Roadside Surveys Roadside surveys were conducted at sunrise on mornings with
