<p>Values are Pearson's correlation coefficients between pairs of reproductive parameters per territory per year, with male identity used to represent territory.</p><p>HD = hatching date of first clutch, Clutch size = number of eggs in first clutch, Egg size = mean egg volume per first clutch, Hatched eggs = number of eggs in first clutch that hatched, Chick wing = mean maximum wing chord of chicks per nest, First fledglings = Number of young that fledged from first nesting attempts, Attempts = number of breeding attempts per male per season, Fledglings per season = number of young fledged per male per season.</p><p>Correlation matrix of reproductive parameters investigated in this study.</p
