Inexplicable inefficiency of avian molt? Insights from an opportunistically breeding arid-zone species, Lichenostomus penicillatus.

Efficiency was, however, highly correlated with metabolic intensity (mass-specific basal metabolic rate, BMR m , kJ.g −1 .d −1 ; r 2 = 0.944, P = <0.0001; Figure 2 ) such that: Phylogenetic regression revealed a strong phylogenetic signal in the relationship between BMR m and conversion efficiency during molt ( Table S2 ), yet the relationship between BMR m and efficiency remained highly significant ( r 2 = 0.884).
