Birds

Winnebago County’s four rivers, prairies, wetlands, and woodlands are magnets for migrating and nesting birds. Over 320 species of birds have been documented here. See the printable Birding Checklist for Winnebago County for a comprehensive listing of all the species that have been documented here and how common they are.

One of the great things about birding is you don’t need piles of expensive equipment to get started. In fact, you’ve got some very important and useful equipment: your eyes and ears. Spring and fall migrations are best times to bird, but nearly any time of year can be rewarding. Some of the most spectacular sightings occur when the trees are bare in winter.
The 10,300 acres of woodlands, prairies, rivers, and marshes protected and managed by the Winnebago County Forest Preserve District provide convenient, safe and fascinating opportunities for year-round birding adventures.
