Table 1 (cont.). Bird species detected on 23 roadside point-count routes in 1998-1999. Total 

 number of point counts was 227 (all routes with 10 points except one with 7 points). 



The problem of overlooking species during counts applies to all species, even relatively 

 common ones such as Brewer's Sparrow, particularly if counts are conducted only once at each 

 point and the time of the count is not optimal Increasing the number of points counted will 

 address this problem for the entire study area, but maximizing species richness at particular 

 points (i.e. approaching 100% accuracy in species detections/point) will require multiple visits to 

 points that are spread across the appropriate times of each breeding season This level of labor- 

 intensive monitoring is probably better applied on a series of plots, where spot-mapping and 

 point counts can be combined with nest searches and nest monitoring (Ralph et al. 1993). 



The route descriptions that follow include a map of each route with all points marked 

 (points 1 and 10 are indicated, with an arrow showing direction the route was run). Route 

 descriptions accompany each map and include a legal description of the start and end points of 

 the route, date and time the route was run, an overview of the dominant vegetation on the route, 

 and a list of species and numbers of individuals counted at each point. These are provided for 

 baseline comparison with future counts conducted on each route, and establish a base for a 

 longer-term monitoring scheme in the study area.
