Table 3. Estimates of phenotypic mean, phenotypic s.d., additive genetic variance (V A), residual variance (V R; here including permanent environmental variance), heritability (h 2) and its s.e., coefficient of additive genetic variance (CVA) and of residual variance (CVR) from our study, and for comparison, the estimates from the Rønning et al. (2007) study on a captive zebra finch population from Norway.

Abbreviation: BMR, basal metabolic rate.
Courtship rate is measured in square-root transformed seconds, BMR in ml O2 consumption per min, mass in g and tarsus and wing length in mm.
