I also meant to concur that 99% of the Merlins in Wisconsin are
columbarius/taiga Merlins. I've seen hundreds if not thousands of Merlins here
in northern Wisconsin and have only been able to identify two individuals of
the Prairie/Richardson's race. Both individuals are digiscoped at
http://www.pbase.com/rbrady/prairiemerlin
Fall migration is likely the best time to find a Prairie Merlin in Wisconsin,
although they are known to breed just across the border in the Twin Cities.
Hawk Ridge in Duluth tallies a just a few individuals each autumn.
