Explore the extensive marshes and wetlands of the Lake Calumet area with local  expert Walter Marcisz.  We will look for breeding summer  residents like Common Gallinules and Monk Parakeets, early  migrant shorebirds, and wandering waders like Snowy Egrets,  Little Blue Herons, and Yellow-crowned Night Herons. We will meet at O’Brien Lock & Dam at 8:00 am. From there we can visit various wetlands like  Hegewisch Marsh, Indian Ridge, Big Marsh, and Burnham  Prairie.

#BirdThePreserves - Cook County’s Big Year @ Heller Nature Center

In 2016, Cook County Forest Preserves sponsored a #BirdthePreserves initiative that unleashed hundreds of birders on more than 20 of the county’s forest preserve sites to see what they could find. Field Museum conservation ecologist Doug Stotz will discuss new information about birds in the Chicago area yielded by this effort, including new insights into distribution, abundance, migration timing and breeding.
