The love bug of Valentine’s Day has apparently taken a bite out of a park ranger at central Iowa’s Saylorville Lake. Ranger Kelly Ulrick is hosting a presentation at the visitor’s center tonight called “Love is in the Air.” She says it’ll cover the secrets of wildlife mating habits.Squirrels and owls are mating in our back yards right now, along with eagles, coyote, fox and many other animals that will bear young later in the spring. Ulrick says she’s not embarrassed by the subject. She says reproducing keeps wildlife populations healthy, and she says they have some unique ways of doing that. Ulrick will be joined tonight by another presenter, an astronomer, who will share love stories in the stars — and he’ll even provide telescopes.
