Repeatability estimates (± standard error) for body mass, body condition, A-egg and B-egg mass for individual females and males.

Repeatabilities for body mass and body condition were calculated for all birds that were recorded at least in two years (“all birds”: N = 241 records of 76 females and N = 222 records of 78 males). Repeatabilities for egg mass were calculated separately for birds that remained with the same partner for at least two years (“same partner”: N = 185 records of 58 females and 64 males) and for birds that paired with different partners for at least two years (“different partner”: N = 70 records for 31 females and N = 41 records for 20 males). P-values in all cases except for the one marked with an asterisk were highly significant (all P < 0.001)
