River Report: 3/26/2007
We started out the morning at the base of Leo’s Bluff near Waukon Junction, IA. We quickly located two adult falcons. The adult male is un-banded. The adult female is: b/g 66/A, a 2005 HY falcon from St. Louis, MO. Her right leg had what looks to Dave Kester and I to be a plain aluminum band. Last season on 5/17/06 we were shocked to find the shell fragments of three recently hatched eggs and one intact pipped egg. Both adult falcons were missing! I had a strange feeling about this loss and wanted to see who showed up this season. I am now more then ever convinced something killed both adults at or around 5/15/07.
I located an adult falcon on the Lansing, IA power plant cliff. It was perched about 20’ from the new nest box. The next few days will tell us just where the falcons choose to lay their eggs.
I worked my way upstream, spending time at each potential cliff nest site. From Lansing, IA north, we saw no falcons until Great Spirit Bluff near Dresbach, MN. Saw two falcons at Queen’s Bluff. Was disappointed to not find any falcons at the Homer, MN cliff where on 3/20/07 Amy Ries saw two falcons.
Found two adult falcons defending Castle Rock cliff across the river from Winona, MN. I did not see any falcons but have had reports from two people seeing one falcon at the Fountain City cliff nest box. Found two adult falcons defending Maassen’s Bluff. It made my day to find one adult falcon defending Twin Bluffs near Nelson, WI. Found two adult falcons at Maiden Rock. The adult female has a purple band on right leg. Was very pleased to find two adult falcons defending West Bluff! How great to have falcons back at this historical cliff after success in 2005 and no falcons in 2006.
Two adult falcons at the Red Wing Grain stack house nest box. Was able to read the band number on the adult female falcon at Horizon Milling in Lake City, MN. She is the resident falcon 29/A. Could make out the letter K on the adult male indicating he is very probably the resident male K/U. This pair is on their second egg as of this writing.
Over the last week or so only one falcon has been seen at the Lynxville, WI cliff. However, just this evening, Dave Kester reports finding two falcons on site. We now need to keep watch on the lock and dam #9 cliff north of Prairie Du Chene, WI.
We'll keep everyone posted! Let us know if you see falcons along the river between roughly Red Wing and LaCrosse.
