January 28, 2021: Mr. North fit tests his nest!

We are less than a month away from egg laying at our Decorah North and Xcel Fort St. Vrain nests!

If you want to see bald eagles, don’t miss the eagle icecapades at Great Spirit Bluff. How many eagles can you count? I counted well over twenty on the ice! Thank you so much to

Where are our eaglets? D27, D35, and D36 phone home!

January 12, 2021: D27's map
