Fig. 1. Ranking of the BMR-residuals (based on RMA-regression of log10
mass-dependent BMR on log10 body mass) from 2002 (filled squares;
average of last two measurements) and 2004 (open squares; average of both
measurements) periods for males (A) and females (B) separately. For each
period all individuals are ranked, with 1 indicating the individual with the
highest BMR-residual.

Fig. 2. Residual values (± 1 S.E.M.) of BMR
(from a RMA-regression) in male (open squares) and female (filled squares)
zebra finches, during the short (A; 20 females and 19 males) and the long (B;
18 females and 18 males) measurement periods. For each period all individuals
are ranked after increasing value of residual BMR.
