Fig. 7. Mapped predicted abundances of Black-throated Green Warbler according to the model of Figure 6. The seven terminal nodes of the CART model and their corresponding estimated mean abundances are shown in the legend. The half-tone screen partially masks areas where little or no data are available (Fig. 3). Note that predictions cover only the boreal and taiga regions as defined in Fig. 3; some regions, such as New Brunswick, where Boreal Avian Modelling Project data exist have therefore been excluded for now.
