Table 1.

Recruitment of offspring into the breeding population as a function of offspring hatching date. Offspring were released in four batches corresponding to offspring hatch date. Because the last release included only 27 offspring from seven clutches, we pooled the last two release batches.

release batch	hatch dates	proportion of offspring recruited (%)
1	9 July to 15 July	16.50
2	16 July to 24 July	20.50
3	25 July to 21 Aug	7.60
