Two young male lions born at the Denver Zoo, now kicked out of their group, will be transferred to separate other zoos as part of a species survival plan, officials announced this week. It’s unclear where these two lions – two-year-old Oskar and three-year-old Tatu – will be sent. They’ll be moved early in April to facilities accredited by the Association of Zoos and Aquariums where they’ll be located with females, Denver Zoo officials said in a Facebook posting. In the wild, male lions typically would leave their birth groups around age two, when they’re big enough to compete with dominant males.
