The Des Moines Water Works Park Foundation wants you to explore Water Works Park as spring valiantly jostles for position in a winter that doesn’t want to end. So naturally foundation leaders spread colorful eggs all across the 1,500-acre park — which is bigger than Central Park in New York City. While you and the kids and grandchildren look for the eggs, the hope is you’ll notice the trees and the 200 bird species that call them home. Warblers, woodpeckers, kingfishers, wood ducks, herons, raptors and owls like to pass through or live there in spring, as well as nesting wood ducks, kingfishers and many others.
