In Wind Cave National Park, the mean percentage of adult females that weaned a litter each year was 47% ± 14%. Reproductive success and survival may be greater in young colonies that have space for expansion. In a young colony (five years) with space for expansion, in Wind Cave National Park, 88% females were pregnant and 81% of young weaned, compared to an old colony (30 years) with no room for expansion, where 90% of females were pregnant and 41% of young were weaned.
