To bird the Bay Beach Wildlife Sanctuary is to experience a premiere “bird funnel.” The adjacent bay sweeps significant concentrations of landbirds through the property each spring and fall. The site is well known for its diversity and abundance of warblers, for which it was designated a Wisconsin Important Birding Area. Thirty-three species of warblers have been seen, including the state’s first confirmed Swainson’s.
Due to diverse habitats, Bay Beach can add a wide variety of bird species to your list in a relatively short visit in any season. Egrets, herons, pelicans, nesting Bald Eagles, Osprey, owls, and waterfowl are just part of the active wildlife community. The refuge has become one of the most predictable sites in the state for Snowy Egrets.
Birds rare to our area continue to make appearances, adding to the excitement and checklist: Tricolored Heron, Eurasian Wigeon, Gyrfalcon, Laughing Gull, Townsend’s Solitaire, and Western Tanager, to name a few.
Most birds can be observed from the hard-surfaced trails and floating boardwalk in and around the main buildings. More adventurous birders can walk the six miles of trails. — Ty Baumann
