To add further to the Merlin question concerning frequency of Prairie Merlin in
WI, Ryan's percentage also holds true for northeastern Illinois where the
Illinois Beach State Park Hawk Watch is located. From 2000-2010 we've counted
3966 Merlin of which 4 were deemed to be Prairie/Richardson's with one well
photographed.

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.
