Here's John's description of the sightings. "We were out on a Critter Cruise, which was the first cruise of the day. At about 1:45pm, after already having stopped to observe two other bald eagles, I spotted the immature eagle flying across the river to a tree. It joined what we can safely say is its parent/adult. As I was shooting a photo of these eagles, a pileated woodpecker flew directly over the boat."
According to Dever, it did not appear that the younger eagle was being fed even though the picture gives the impression that it was begging for some food.
While we can't guarantee sightings like this, winter is a great time to spot bald eagles in the Tennessee River Gorge.
