Warbler Migration Cranks Up; Raptors Take Flight Too

The bulk of Wisconsin’s warbler migration occurs over the month of September, many species sporting different plumages than spring that challenge even the most seasoned birders. The magnolia warbler is one such bird. / Photo Credit: Ryan Brady

Warbler Migration Firing On All Cylinders Statewide; Look For Raptors Too

Are you ready, birders?

September is peak migration season for our long distance migrants that feed heavily on insects and winter in the tropics. Every oriole, hummingbird and swallow you see now may be your last until next spring, especially in the north, while grosbeaks, tanagers, catbirds and buntings continue their exodus as well. 

Warbler migration is now firing on all cylinders statewide, with the best numbers and diversity to come around mid-month.
