FALL MIGRATION OF CANADA GEESE
To some, the name Horicon Marsh has almost become synonymous with Canada geese. Each fall the largest migratory flock of Canada geese in the world migrates through Horicon Marsh with peak numbers reaching more than 200,000! The geese begin to arrive in mid-September, but for many the most popular time to see this fall spectacle is in mid-October as numbers approach the fall peak, other wildlife is still abundant, and fall colors paint a perfect background.
