I grew up near St. Maries and return almost every year. As long as I can remember there have been osprey nests on the Benewah bridge. Osprey's are very plentiful on both the St.Joe and CDA Rivers and their drainage. I have never seen an eagle or eagles nest on the Benewah Bridge. There are bald eagles in the area but I have never seen them nesting on the communication poles. There is a website for osprey nests in the area and it lists this particular nest as recently as a few months ago.
