Madison, WI – Male hummingbirds are among the first to head south as Wisconsin enters the fall migration season, with peak numbers of the tiny birds typically seen from mid-August through early September. Females and younger hummingbirds usually remain a bit longer before making their way toward Central America.
According to the Wisconsin Department of Natural Resources (DNR), homeowners can play a role in helping the birds refuel for their long journey. The agency recommends filling feeders with homemade nectar by boiling four parts water to one part sugar, skipping dyes or honey, and allowing the mixture to cool before placing it in a brightly colored feeder.
Officials also suggest placing feeders in shaded areas when possible and cleaning them every two to three days in hot weather, or at least once a week as temperatures cool. Planting native flowers such as cardinal flower, wild bergamot and spotted jewelweed provides another natural food source. The DNR further advised residents to avoid pesticides so hummingbirds and other wildlife can access insects and spiders for nourishment.
As for when to remove feeders, the DNR recommends waiting until no sooner than October and at least two weeks after the last sighting of a hummingbird in the area. Feeding does not prevent migration, the agency noted, and can provide critical late-season energy for the birds making the long trip south.
Wildlife experts emphasize that providing food sources into the early fall season is especially helpful for younger birds and late travelers, ensuring they have the strength to complete their migration successfully.
