Figure 2. Fledging success of individual pairs.

(A) Fledging success per brood (%) of the nth time a pair had a brood. The dashed line indicates a quadratic regression (y =−2.57x² + 21.95x + 33.18). (B) Fledging success per brood (%) plotted against the total number of times each pair has bred. The dashed line indicates a logarithmic regression (y = 21.75*log(x) + 41.19). Large grey dots in a, b indicate the mean of all fledging successes per brood ± SE, bars indicate number of broods (A) and number of pairs (B), respectively. The small dots represent each brood. Shading intensity increases with overlap with other broods.
