Mom, behind, with fledgling daughter, front. Easy to see one way to tell the young from the old, the adults have yellow eyes where the young have red-orange.

Here is another way to tell young from old which is a little easier as this difference can be seen at greater distances. The older osprey have mostly all dark upper wings and backs as seen here:

By comparison, the fledglings have silvery tips on the feathers of their wings and backs:

The juveniles will loose these feathers in their next molt, which won't be until next year. As they won't return from their migration for another 18 months (chicks hatched this summer will stay south all next year and return to the area of their birth in 2022) they will look like adults when they return though they won't be quite ready for breeding for another year beyond that.
