Fig. 8. Estimated prediction reliabilities of the seven terminal nodes in the CART model for Black-throated GreenWarbler (Fig. 6). The half-tone screen partially masks areas where little or no data are available. Note that this map covers 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.
