Jon Wuepper, a member of the Berrien Birding Club, has compiled a list of newspaper accounts
of encounters (predominantly by hunters) with Passenger Pigeons in Berrien County
spanning the period from 1839-1879. According to Wuepper:
The last known Passenger Pigeon recorded in Berrien County, Michigan[,] occurred on 27 May 1894, when a flock of about 20 birds were [sic] observed in the southern part of the county, about three miles from the Indiana state line.
That would put this sighting within 10 miles of the place where I was born some 52 years too late to ever have the opportunity of seeing a real live Passenger Pigeon.
