Beginning from Montrose Harbor and continuing south through the Lincoln Park Sanctuary, Belmont Harbor, past Grant Park and south to Jackson Park and the Paul O. Douglas Nature Sanctuary, lie miles of Lake Michigan waterfront property, much of which is owned or manged by the Chicago Park District and contains copious vegetation. These areas are known as migrant traps because they capture birds flying south or north along Lake Michigan who become famished and need a place to rest. Various groups, too numerous to mention, which include volunteers and government and park distirct officials, have worked to improve the habitat needed for these migratory birds to rest and refuel.
These areas combined provide tremendous benefits to migratory birds.
Shorebirds, landbirds and raptors all make temporary homes along the Chicago lakefront -- and some species even remain to nest here.
More than three-fourths of all bird species seen in Illinois have passed through or paused to rest and feed along the Chicago lakefront. The vegetation along the lakefront provides the rest and shelter birds need as they are migrating along Lake Michigan, which is on the Mississippi Flyway. In April, May, August, and September you can count at least 25 species of warblers here, many in sizeable numbers, along with orioles, grosbeaks, hummingbirds, vireos, flycatchers, sparrows, swallows and martins. Along the lakefront, Peregrine Falcons hunt for shorebirds and other species. Myriad duck species, scoters and loons also fly along the shoreline during migration.
Continued restoration at the lakefront parks will ensure migratory birds will have a place to rest and feed each spring and fall.
This site was chosen as an IBA because it met the criteria for migrants and Black-crowned Night-Herons.
