And there are many unmarked offspring of banded pairs. People can call myself or Donna Compton at Hennepin Parks at 476-4663 to give reports. We would greatly appreciate hearing from people.

We watched them take off and fly north above us. Trumpeters, however, migrate in small family groups and seem to fly lower. Contributed by Madeleine Linck on 18 Mar 1995. Last updated by Marcus Martin on 2 February 1999.
