Some of my favorite photo subjects are raptors (Eagles, Hawks, Ospreys, Falcons, etc.). This is an Osprey bringing nesting materials to build the nest, from a trip years ago to the Brigantine Division of the Edwin B. Forsythe National Wildlife Refuge in Oceanville NJ. Image shot with a Canon 400mm DO lens.
Osprey often keep bringing sticks to their nests even after they are built and there are young chicks in the nest. I do not know if it is for repairs or just what they do. It is fun to see them swoop them up from the water by the shore.
