Mature (4 years old+) Bald Eagle riding a warm air thermal, Fillmore County, Mn. Took a 30 mile drive through the hill and valley country of our area. We saw 13 Bald Eagles, and looked at 6 eagle nests. Only one nest had Bald Eagles sitting on the nest, all the others were not in use yet, but did have adults within a mile or so. The nest with a sitting eagle probably already has eggs. The others will nest fairly soon. We will check the nests on a weekly basis and post what we find.
