Chicago Audubon Society’s efforts to make Chicago’s buildings safer for birds

Can you pitch in to help us buy some shrubs? Chicago Audubon, the River Park Advisory Council and Chicago Park District plan to create migratory landbird habitat by adding native shrubs and understory trees. This project will expand the capacity of the habitat at Ronan Park and extend a quality riparian ecosystem farther north.

The Chicago Audubon Society Board of Directors is excited to welcome Matt Igleski as our first Executive Director.

Please help protect bird habitat along the Chicago River. Lighting, noise and tree removal are not appropriate for this quiet wildlife corridor.

Prothonotary warbler is one of the rarer nesting birds in our region. It likes swamps - which are wooded wetlands. Confirming its nest is a task for the adventurous. Here are the findings of a few intrepid birders.

The Chicago Audubon Board and the CAS Board Committee working on the name change feel strongly that picking a name in concert with other groups is the most effective way to continue to benefit from a unified brand.

Researchers are doing a much-needed study of Black-crowned Night-herons, and you might be able to help by contributing your sightings of banded birds anywhere in the Chicago area or interactions you observe at Big Marsh.

On the Sauk Trail Blitz, we discovered a lovely site for birding during the nesting season
