Biologist Lynn Rogers says Lily gave birth just after 11:30 a.m. Central Time Friday in her den, which is equipped with a video camera.

Rogers and his North American Bear Center put a camera in Lily's den outside Ely (EE'-lee), Minn., that streams her activity live over the Internet.
Rogers says he doesn't know if the cub is male or female. He says a bear's first litter is typically one or two cubs, so the 3-year-old Lily might go into labor and deliver a second cub
