These hedgehogs have caused serious declines in internationally important ground-nesting shorebirds, and population control is now being attempted. Sexual behaviour commenced in late April, a few days after the main emergence from hibernation. It peaked in mid- May and again in late June/early July, and ceased by mid-August. Females were promiscuous and were estimated to have sexual encounters (although not necessarily matings) with at least five males during the main mating period. Twothirds of females attempted to breed for the first time in their second calendar year (i.e. as sub-adults), and the rest in their third calendar year (i.e. as adults). At least 96{%} (n=27) of adult females attempted to breed in the early part of the season (litters born in June). The vast majority (81{%</p>
