Paul, the Sandhill Crane subspecies "tabida" (= "Greater"), which occurs in
Wisconsin (as well as MN, MI, and southern Ontario) is the largest of the
subspecies. There is, however, a substantial sexual dimorphism, with males
being noticeably larger and taller than females -- when seen side by side.
More than likely you saw a male flying with two females.

To all -- I just got back from an errand with my daughter. As we
pulled on to our street I saw 3 cranes heading NW and saw 1 of them
was a bit larger than the other 2. To be sure, Rachael concurred with me.
Having checked the book I see we saw Grus canadensis tabida. Has
anyone else seen the "larger more southern species" around here before?
