Meet Peregrine Falcon Nova at Great Spirit Bluff!

Nova, our new female falcon at Great Spirit Bluff. Isn't she beautiful! Notice that she is not banded.

I loved all of these videos, but I especially loved Mom pulling grass, DM2 stepping on Mom’s tale while presenting his cornhusk arrangement, funny moments at the Valley of the Norths, and Mr. North’s giant stick (Mr. North is Paul Bunyan!). The tribute to Michelle brought tears to my eyes. Thanks for watching, learning, sharing, and especially for caring. Decorah Eagles Egg one is
