ONCA, Neb. (AP) — People are invited to enjoy the wonders of the spring bird migration at Ponca State Park during Marsh Madness.

The park's location adjacent to the Missouri River presents a significant flyway that serves as the feeding, breeding and staging ground for migratory birds. The park is listed as an "Important Bird Area" by the National Audubon Society, with nearly 300 species sighted and more than 70 of those breeding in the area.

Guided sunrise and sunset waterfowl blind viewings are scheduled on Saturday, March 10 and March 17, but space is limited. Call the park at 402-755-2284 for reservations. Go to www.Calendar.outdoornebraska.gov for more details.

A park vehicle entry permit is required. The park sits about a mile north of Ponca in northeast Nebraska's Dixon County.
