Abstract

Members of the avian subfamily Carduelinae have served as subjects of numerous investigations on adaptations of small birds to cold winters (Salt, 1952; Dawson and Tordoff, 1964; West, 1972; Dawson and Carey, 1976; Carey et al. 1978; Weathers et al. 1980; Marsh et al. 1984; Reinertsen, 1986; Yacoe and Dawson, 1983; and others). These birds, including goldfinches, pine siskins, house finches, grosbeaks, crossbills, and redpolls, are particularly well suited for such study because of their principally northern distribution and small body sizes. Their success in cold climates appears to be linked in part to a type of metabolic acclimatization, involving enhanced capabilities for sustained elevated production of heat for prolonged periods (Dawson and Carey, 1976; Dawson et al. 1983a, b; Dawson and Marsh, 1988).
