Table 3. Between-site initial variance (τ22) and between-site trend variance (τ32) estimates, expressed as coefficients of variation. Target codes are as in Fig. 2. Variance estimates are derived from BBS (Breeding Bird Survey) data collected from the closed boreal forest physiographic region of Alberta, Canada from 1992 to 1998 (τ22) and 1989 to 1998 (τ32).
